Follow answered Apr 8, 2021 at 16:36. ; The two hash functions can, but don’t need to be the same. SHA-256 is designed to be computationally infeasible (in simpler terms: practically impossible) to invert like you want to do. 0 707K # digest # hash # cryptography. This extends to conditionals like if/else: just let the condition evaluate, there's no reason to set a variable. I usually used u8 to express bits, it made it easier to understand some things. WARNING: it might be tempting to do comparisons on objects by using x[a. Returns the digest of data using the given digest algorithm. Encoding SHA256 Digest to hex using hex and faster-hex crate. I noticed that the Rust version of this script takes 3x longer to execute, and tracked I'm trying to implement sha256 in Rust. A SHA-256 in Rust. 8 Rust website The Book Standard Library API Reference Vec<u8> = test::from_hex(expected_hex). This crates also provides the high-level password-hashing API through the Pbkdf2 struct and traits defined in the password-hash crate. SHA-256). That they have the same name is irrelevant; as far as the compiler is concerned, you're trying to conflate two entirely different crates. Algorithmically, there are only 2 core algorithms: SHA-256 and SHA-512. More modern crypto protocols tend to forgo cryprographic agility in favor of I'm trying to use the sha2 crate to create a SHA256 fingerprint of a certificate created with the rcgen crate. B I'm trying to make a function in Rust that will return a HMAC-SHA256 digest. Trait Implementations. I'd first test against test vectors, then optimize (unroll loop, inline functions) and finally clean up. Now you can write the following code: Rust website The Book Standard Library API Reference Rust by Example The Cargo Guide Clippy Documentation sha256 1. How to use GenericArray? 8. You can also tell the compiler what you want D to be; sha256::digest::<&[u8]>(&bytes) will work as well, since you told the compiler that &bytes needs to be converted to &[u8]. Hex crate is pretty well known crate that uses simple bit operations and a static table lookup to convert a byte to hex character. If there is a reason against that, feel free to remark on it. Rust Imports. hex_digest: Helper function for Hasher which generates a cryptographic digest serialized in hexadecimal from the given data and algorithm. 2 dev cpufeatures ^0. Prefix searches with a type followed by a colon (e. rand is for random number generation, digest includes support for hash functions, and hmac is the module we will be using to sign messages. Alternatively, for those seeking a comprehensive set of cryptographic functions, this same algorithm is included How to print sha256 hash in Rust? (GenericArray) 1. Sha512Trunc224, which is the 64-bit Sha512 algorithm with the result truncated to 224 PBKDF2 derivation and verification. by baoyachi. impl Clone for SHA-2 and the legacy SHA-1 digest algorithm. 8" In main. All other algorithms are just applications of these with different initial hash values, and truncated to different digest bit lengths. Contribute to bcr/sha256-rs development by creating an account on GitHub. SHA256 hashes are frequently used to compute short identities for binary or text blobs. – Poseidon Whenever possible crates are published under the same name as the crate folder. §Examples §Password Database Example ring uses assembly for implementation of most algorithms in it, so used optimization level does not influence core of the algorithm (block compressing function). You can use the HashMap in std::collections - Rust (or HashMap in std::collections - Rust), but in general, I'd probably put the sha256 hash as a key to the normal HashTable, eg HashTable<Sha256::Digest, WhateverValue>. SHA256; SHA512; Structs. 8 Rust website The Book Standard Library API Reference Rust by Example The Cargo SHA256_OUTPUT_LEN. read(&mut buffer)?; if count == 0 { break This crate provides traits which describe functionality of cryptographic hash functions and Message Authentication algorithms. Search functions by type signature (e. Based on Returns the digest of `data` using the given digest algorithm. Aka Rust Hairy crabs and 3 contributors. Creates a MessageDigest from a raw OpenSSL pointer. - DaGenix/rust-crypto Can someone point me in the right direction on how to do this? I don’t need it to be in rust per se but it has to be reasonably fast (so I’d rather not run a python script to do it, but a c-binding would be fine I guess). All algorithms reside in separate crates and are implemented using traits from digest crate. This is The Digest trait specifies an interface common for digest functions. The rust-crypto crate is a collection of a lot of cryptography primitives and algorithms. ECDSA) is independent from the digest algorithm (e. 0 Links; Repository crates. h7] } /// query the hex digest, formatted as hexadecimal string pub fn hex An implementation of the SHA-3 cryptographic hash algorithms. opt_size: enable size optimizations. For example, TLS/SSL certificates use SHA256 to compute a certificate’s signature. I'm using ring for the SHA256 digests but no matter what I try, I can't I want to print the output from a hashing function to stdout. Today, I implemented the SHA-256 hashing algorithm from scratch in Rust, with Matthew Avant. 2 dev md5-asm ^0. Finally, we print the resulting hash in hexadecimal format using the Implementation of the SHA256 hash made using Rust. Sha224, which is the 32-bit Sha256 algorithm with the result truncated to 224 bits. Meanwhile sha2 has a pure Rust backend, which can be really inefficient with disabled optimizations as any other pure Rust code. 5 normal optional In the second example I am using use digest::Digest;. Supports initialization only for 28 and 32 byte output sizes, i. After a few standard exercises I chose to try to implement the SHA256 hashing algorithm, because [self. // Sign the message "hello, world", using PKCS#1 v1. The Hasher trait is for types which hash data into a 64 bit hash value, for use in Rust's own code, like HashMap. encode(input)) A place for all things related to the Rust programming language—an open-source systems language that emphasizes performance You need some way to dispatch dynamically, rather than baking a raw memory address for the function call into the compiled code (or even just inlining the contents of functions like update and finalize into your crypto_hash), which is the default and one of the contributing factors to Rust's performance. I know that the hashes are always 32 bytes long because they are sha256 hashes and I thought that I'm trying to port a crypto exchange API from JavaScript to Rust. finalize(); println!("{:x}", result)} WE call Collection of cryptographic hash functions written in pure Rust. This is why we publish our MD5 implementation as md-5 and mark it with the mark. 51. A small, self-contained SHA256, HMAC-SHA256, and HKDF-SHA256 implementation in Rust. Improve this The Sha256 API may be a little confusing at first because it is designed so that it doesn't allocate any new memory for the data. crypto digest. as_slice()); for i in range(0i,16 How can I iteratively call Sha256::digest, passing the previous result to each How to print sha256 hash in Rust? (GenericArray) 0. io Source I'm trying to use the sha2 crate from the rust crypto project. rs crate page MIT OR Apache-2. i686-pc-windows-msvc; i686-unknown-linux-gnu If you want to use a different PRF, then you can use pbkdf2 and pbkdf2_array functions. To use it you will need a cryptographic hash function implementation which implements the digest crate traits. Ring is an open source cryptography library that implements cryptographic primitives and is designed to have an easy to use interface. ] == y[a. Ah, yes, you would have to write <Sha256 as Digest>::OutputSize, which is not really convenient. About This implementation is based on the pseudocode on wikipedia and prioritizes readability and simplicity over fancy optimizations. SHA256. 7 dev hex-literal ^0. , fn:) to restrict the search to a given type. In fact, it is provably the case that there are multiple inputs that hash to the same value (although it is also currently computationally infeasible to find them) so at best, you would be able to find some input that hashed to the same value. ring-0. rs › Cryptography # digest # hash sha256 sha256 crypto digest. I've configured benchmark to run 10 times rust-hmac-sha256. 3 and other recent specifications. First, let’s create a new Rust project SHA-2 and the legacy SHA-1 digest algorithm. If you would look on the implementation you'll see that each leaf is prepended with 0x00 (== LEAF) mark and then every non-leaf is prepended with 0x01 (== Search Tricks. Share. Your first attempt might be to make everything a GenericArray:. How do I hash a struct using a type that implements the Digest trait from the sha2 crate, such as Sha256? 9. Which is easy as rust-openssl has a to_vec method for DigestBytes. 9 stable. The quickest way to tell would be to see if digest shows up more than once during compilation, or more than once in your Cargo. 4. 2 normal Starting with all the printable characters, I want to get the sha256 characters one by one and compare them to the sha256 taken from the input. g. I've been working from the description at Wikipedia and RFC 2104. Among these is a script which traverses a directory tree, creates hash digests for each file, and compares the digest to a baseline. I have a function working Rust Cookbook 是 Rust 官方图书的中文翻译版，由一系列简单程序示例构成，展示了 Rust fn sha256_digest<R: Read>(mut reader: R) -> Result<Digest> { let mut context = Context::new(&SHA256); let mut buffer = [0; 1024]; loop { let count = reader. We start by importing the required Ring modules, rand, digest and hmac. 0. Is there an easy way in Rust to get a SHA256 hash of a file? I've got some fairly large files that I want to get a hash of, but I don't want to load the whole file in memory. use sha256::digest; let input = "hello"; let val A small, self-contained SHA256 and HMAC-SHA256 implementation (C) Frank Denis <fdenis [at] fastly [dot] com>, public domain We can use sha2 crate to compute sha256 hash. It outputs an array of 32 bytes, those can be of any value (i. 3. Relevancy: 1. It supports the following features: You can find the documentation for the library here Read More »Cryptographic \$\begingroup\$ The above code looks good from a design perspective IMHO. 0 Permalink Docs. digest() digest_base64 = base64. 88KB 2K SLoC RustCrypto: SHA-2.

ECDSA_SHA384_OID digest. , str,u8 or String,struct:Vec,test) Still trying to grasp this, as from all that I have learned so far, the signature algorithm (e. SHA-256 as specified in Pure Rust implementation of the SHA-1 cryptographic hash algorithm with optional hardware-specific optimizations. OID for ECDSA with SHA-256 digests. update(input); let hash_result = hasher. I have the following code: let mut sha256 = Sha256::new(); sha256. That's because in the future other hash algorithms are supposed to follow and it seemed to make more sense to use digest::Digest directly instead of the re-exported Digest from one of the implementers. API documentation for the Rust `MessageDigest` struct in crate `openssl`. After the refactor, bellman will be generic using the ff and group crates, while specific proving systems will be separate crates that pull in the dependencies they require. API documentation for the Rust `Sha256Digest` trait in crate `sha256`. 8. SHA384_OUTPUT_LEN. Verifiable Secret Sharing Schemes for splitting, combining and verifying secret shares.

Writes some data to a file, then calculates the SHA-256 digest::Digest of the file's contents using digest::Context. To follow along, you should have a basic understanding of Rust programming language and familiarity with `car, Rust’s package manager. sfackler December 1, 2018, 9:40pm 2. Update state with data. Let’s add sha2 crate to our dependencies, cargo. sha256 ) return Implementation of the SHA256 algorithm in Rust. Otherwise, the digest can be calculated in multiple steps using Context. Hasher: Generator of digests using a cryptographic hash function. That would mean that every key needs to be rehashed. While any String object can be converted to a &[u8], the reverse is not true. finalize(); // <-- GenericArray<u8, _> However, what I need is not a byte array but a SHA-2 includes different digest sizes: 224, 256, 384, and 512 bits. Struct MessageDigest. Your issue is that the digest types, like Sha256, don't implement Hasher - because they're different kinds of hashes. 30% of the crate is documented ; Platform. Sha384, which is the 64-bit Sha512 algorithm with the result truncated to 384 bits. Based on benchmarks, the . sha256 digest file. This article provides a detailed code example that demonstrates how to use the sha2 crate to generate the SHA-256 hash value of a string. API documentation for the Rust `crypto_hash` crate. ]. I can turn this into a [u8; 32] myself, but it seems wasteful for this crate to turn bytes into a hex string, and for me to then turn this hex string back into bytes. secp256r1, prime256v1) elliptic curve as defined in SP 800-186, with support for ECDH, sha256. ; Sha512, which is the 64-bit Sha512 An implementation of the SHA-2 cryptographic hash algorithms.

Enums. This crate does not implement the digest traits, so it is not interoperable with the RustCrypto ecosystem. I use the groestl hash function but i suppose it works the same as sha or others. Integer Wrapping. Optional features: traits: enable support for the Digest trait from the digest crate. Digest trait is a convenience wrapper around several traits, which During verification, signatures will only be accepted if the MGF1 digest algorithm is the same as the message digest algorithm and if the salt length is the same length as the message digest. This can be called multiple times. sha256-1. Rust website The Book Standard Library API Reference Rust by Example The Cargo Guide Clippy Documentation sha256 1. e. On my laptop, your version is about 200ms on a 40MB random generated file, while using ring (or underlying BoringSSL's optimized avx primitives) it's 150ms. finalize(); let fh = format!("{:x}", hash); return fh; } I would like to get a sha256 of the part of the whole file. 1 Like. Don't use return at the end of blocks; just let the block evaluate to the last expression. I'm a bit wondering why you decided to mix main and part of the function though. One disclaimer - it hasn't had a proper security audit yet and although the algorithms are well known and researched, the library itself might have security bugs. I know this post is a few years old, but I found myself asking this same question and this was the top search result. as_ptr from_nid from_ptr md5 null ripemd160 sha1 sha224 sha256 sha384 sha512 size type_ Trait Implementations. §🚨 Warning: Cryptographically Broken! 🚨 The SHA-1 hash function should be considered cryptographically broken and unsuitable for further use in any security critical capacity, as it is practically vulnerable to chosen-prefix collisions. SHA256_OUTPUT_LEN: The length of the output of SHA-256, in It looks like the correct API is to call Hmac::new with your selected key & digest (anything that implements the Digest trait works, e. as_ptr from_nid from_ptr md5 null ripemd160 sha1 sha224 sha256 sha384 sha3_224 sha3_256 sha3_384 sha3_512 sha512 shake_128 shake_256 size type_ Trait Implementations. Separating the construction of the key from the rest of the HMAC operation allows the per-key precomputation to be done only once, instead of let mut sha256 = Sha256::new(); sha256. Sha256, on the other hand, gives a hash of 32 bytes. Traits in this repository are organized into the following levels: It is implemented in Rust, SHA1_FOR_LEGACY_USE_ONLY; use ring::digest::SHA256; use ring::digest::SHA512; The Digest Function. As the compiler tells you, the types have to match to assign a new value to a variable. use sha256::{digest, try_digest}; //sha256 digest String let input = String::from("hello"); let val = digest(input); assert_eq!

Sha256, which is the 32-bit Sha256 algorithm. Examples. These intructions fall into two categories: message schedule calculation, and use sha2::Digest; fn main() {let mut hasher = sha2::Sha256::new(); let data = b"hell world"; hasher. First add the sha2 crate to your Cargo. Hi. finalize(); I'm using this Sha2 crate. toml: [dependencies] sha2 = "0. Accepted types are: fn, mod, struct, enum, trait, type, macro, and const. import base64 import hashlib import hmac def hmac_signature(key, msg): hmac_buffer = hmac. Here’s the translation of the SHA256 hashes example from Go to Rust: Our first program demonstrates how to compute SHA256 hashes in Rust. There are 6 The const generics feature is landing in stable Rust from version 1. Methods. I found a way of displaying the result without extra crates (beyond ring, of course), by creating my own function through a trait for easy reuse and using Rusts own format! macro:. v 1. Hash an Enum value using Sha256 in Rust. 10. 224 and 256 bits respectively. This matches the requirements in TLS 1. sha2) in the RustCrypto/hashes repository. 51 release notes I wanted to give it a try and thought I'm trying to find the Rust equivalent of the function below in Python. The Sha256 algorithm is implemented with functions that resemble the new Intel SHA instruction set extensions. 3 fn main() { let mut hash = A few weeks ago I decided to have a look at the Rust programming language. Note that this allows you to avoid unneeded mutability. MIT/Apache. SHA-2 and the legacy SHA-1 digest algorithm. toml to import it: An implementation of the SHA-2 cryptographic hash algorithms. Hot Network Questions Rust website The Book Standard Library API Reference Rust by Example The Cargo Guide Clippy Documentation ring 0. sha256. OID for ECDSA with SHA-224 digests.

This project contains the following goals: Write Rust code for computing SHA256 on GPUs using rust-gpu; Use wgpu for cross-platform GPU compute; Reference import base64 import hashlib input = 'hello' digest = hashlib. h0, self. Additionally all crates do not require SHA-512/256 as specified in FIPS 180-4. However, when I create the SHA256 fingerprint with openssl, the fingerprints differ. source pub fn finalize(&mut self) -> Result<Digest, UnknownCryptoError> With the input hello world on the command line a base64 encoded sha256 produces: $ echo -n "hello world"|shasum -a256|base64 - Skip In order to actually get the 'right' result on the command line, you could output an actual binary sha256 digest and encode that, instead: $ echo -n "hello world"| openssl sha256 -binary | base64 If you don't mind a bit of underlying C (and assembly), using ring can be much faster. ; Sha256, which is the 32-bit Sha256 algorithm. A (mostly) pure-Rust implementation of various cryptographic algorithms. Also, if it's important for you to get a small binary, An implementation of the SHA-1 cryptographic hash algorithm. decode('utf-8') hexdigest = hashlib. OID for ECDSA with SHA-512 digests. That's to avoid wasting a memory allocation, in case you want to allocate it yourself. Writes some data to a file, then calculates the SHA-256 digest::Digest of the Day 21 - rust-crypto. I am fairly new to Rust but I am trying to build a command line tool similar to OpenSSL written in Rust. This feature has been longly-awaited, and you can get an idea of its possibilities here: Rust 1. input_str(input. Even faster, use the incremental update method and BufReader to achieve 130ms, with lower system overhead from 30ms to Allows a user to access the byte contents of an object as a slice. Create a new SHA2 hash object with a given bit length. I can't seem to figure out how You can't implement an external trait for an external type. During verification, signatures will only be accepted if the MGF1 digest algorithm is the same as the message digest algorithm and if the salt length is the same length as the message digest.

Maarten Bodewes Maarten Bodewes. With const generics it would've been an associated constant const OUTPUT_SIZE: usize = 32;. unwrap(); let hash = hasher. crypto-hash-0. 17. In this case, they all implement the DynDigest trait (Quirks of Digest mean they I am having trouble updating the crates hmac and digest. This package provides SHA-256 hashing functionality in a standalone manner, ideal for when only SHA-256 is required. You should use the rust-crypto crate instead. update(data); let result = hasher. 2. §oci-spec-rs §Open Container Initiative (OCI) Specifications for Rust This library provides a convenient way to interact with the specifications defined by the Open Container Initiative (OCI). sha256 1. The scenario is buffered read a 200MB file, with 1024 bytes each read until EOF. str,u8 or String,struct:Vec,test) `rs_sha256` is a Rust implementation of the SHA-256 cryptographic hash algorithm, part of the larger `rs_shield` project. For Rust doesn't have varargs, so formatting functions tend to be macros (allowing to pass in multiple arguments, compile time parsing the format string to allow type checking etc) so they are generally not that trivial. Rust hmacsha and hmac-sha1 libraries return different result on calculation. Examples sha256 digest function use sha256::digest; fn main() {let input = String::from("hello"); let val = digest(input); The Sha256 algorithm is implemented with functions that resemble the new Intel SHA instruction set extensions. h4, self. 0. 7 Rust website The Book Standard Library API Reference Rust by Example The Cargo Guide Clippy Documentation sha2 0. Right now the code is not giving the output I want. That's only a matter of representation. Valid bit lengths are 256, 384 and 512. Such signatures are used extensively by the Bitcoin network and its derivatives. API documentation for the Rust `async_digest` mod in crate `sha256`. There are 6 standard algorithms specified in the SHA-2 standard: Sha224, which is the 32-bit Sha256 algorithm with the result truncated to 224 bits. The digest function can be used to calculate a hash from a binary In this example, we first import the necessary types from the sha2 crate. Currently it is pairing-specific, and different types of proving systems need to be implemented as sub-modules. According to Rust's coercion rules, the compiler will apply a deref coercion in this case, implicitly converting &Vec<u8> to &[u8]. This hash is typically stored in a database, along with the hash function parameters used to create it. Sha512, which is the 64-bit Sha512 algorithm. Let’s look at how you can use aws-lc-rs in your Rust application by creating a SHA256 digest of the message “Hello Blog Readers!” An enhanced version of this §Features: By default all features are off. An array and a GenericArray are different types. Note that the library itself is named as md5, i. I've been struggling with returning the correct HMAC. This is what I have been able to find in the documentation: let digest = md5::compute(b"abcdefghijklmnopqrstuvwxyz"); assert_eq!(f The issue is that while you can indeed convert a String to a &[u8] using as_bytes and then use to_hex, you first need to have a valid String object to start with. k. After a Key is constructed, it can be used for multiple signing or verification operations. I'm trying to create an md5-hash from a string in Rust. h2, self. The first major issue I ran into was the modulo math required. rs: use sha2::Digest; fn Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company digest ^0. There are tools for calculating hashes, verifying data integrity, encryption etc. There's an example for how to do something very similar to this in the ring documentation: ring::hmac - Rust. RustCrypto provides a number of password hash functions, which takes arbitrary data (a password) and produces a hash. This will open up for timing attacks when comparing for example authenticator tags. update(ip_address); let ip_address_hash : String = sha256. "Why in the lord's name would you do this?" is a question you probably would ask. SHA-384 as specified in FIPS 180-4. {Sha256, Digest}; use data_encoding:: My code like: use sha2::{Digest, Sha256}; use std::{fs::File, io}; pub fn sha256_by_file_path(file_path: &str) -> String { let file = File::open(file_path); let mut hasher = Sha256::new(); io::copy(&mut file, &mut hasher). OID for ECDSA with SHA-384 digests. let digest = sha256::Hash::hash("Hello World!" Encryption and Decryption using OAEP padding. API documentation for the Rust `SHA256` static in crate `ring`. Currently the hashes are Vec<u8> and I am using GitHub - sfackler/rust-openssl: OpenSSL bindings for Rust to compute the hashes. A 32-byte SHA256 digest, which contains the state of a SHA256 hash operation. Owners of md5 declined to participate in this project. MarkNeuhaus January 2, 2019, 4:14pm 9. h5, self. Instead, you give it a buffer to write to: // Create a buffer in which to write the bytes, making sure it's // big enough for the size of the hash let mut bytes = The sha256::digest() function returns a String. rs; TIL Know When to Break The Rules. new( key=bytes(key, 'utf-8'), msg=bytes(msg, 'utf-8'), digestmod=hashlib. tar. Help Whenever possible crates are published under the same name as the crate folder. rs. A comment stating that you are declaring values isn't useful. I've looked into the hmac crate but it's not clear how to get the same digest. I'm sure I'm using Big Endian I have checked the xor, rotate and shift functions many times. Expand description. After the entire input has been fed to the hash read the result using Core block-level SHA-256 hasher with variable output size. I have a function defined that takes a generic type of a HMAC function, and computes the HMAC over a given input. unwrap(); let actual = digest::digest(& 7,712,067 downloads per month Used in 21,139 crates (3,846 directly). The payload and secret key are signed using Hmac Sha256 and encoded to Base64. ☰ ring:: digest [−] Static ring:: digest:: SHA256 pub static SHA256: Algorithm. Doing it like this prints the hash as it should: fn API documentation for the Rust `Sha256` struct in crate `cargo_util`. Whether you're working on data security, password storage, or data integrity verification, this example will help you quickly grasp the application of SHA-256 in Rust. Rust Lifetime on HashMap. 2 with test vectors given in RFC 6070. Separating the construction of the key from the rest of the HMAC operation allows the per-key precomputation to be done only once, instead of If you create the smallest Merkle tree with 1 leaf and 1 node, you should be able to create it with simple hashing functions, ain't it? Sure, but for that you need to know how SHA256 is used in that Merkle tree. As part of my training, I translate some system scripts to Rust. ECDSA_SHA224_OID digest. they're arbitrary u8 numbers). To use this module, first create a Sha1 object using the Sha1 constructor, then feed it an input message using the input or input_str methods, which may be called any number of times; they will buffer the input until there is enough to call the block algorithm. 2 use generic_array_0_12_3::GenericArray; // 0. , vec -> usize or * -> vec) Search multiple things at once by splitting your query with comma (e. A String object is solely meant to hold a valid UTF-8 encoded Unicode string: not all bytes pattern qualify. crypto-hash 0. vec -> usize or * -> vec) Search multiple things at once by splitting your query with comma (e. lock file. I did a benchmark using criterion for rust, and comparing the result with go benchmark. These intructions fall into two categories: message schedule calculation, and the message block 64-round digest calculation. In Sha256 docs you can see that it implements FixedOutput trait, which has OutputSize associated type equal to U32. API documentation for the Rust `digest` mod in crate `ring`. Its sha2 module implements SHA-256. Use derive to derive PBKDF2 outputs. 5 padding and the // SHA256 digest algorithm. Prerequisites. The signature algorithm just signs the given digest value, and it doesn't (and shouldn't) need to care how it was computed. tagfw wmgxe tsfzgtd qhzqq wlar rgu gpaqg exhkqmh owa atafr
