chksum-hash-sha2
An implementation of SHA-2 hash algorithms for batch and stream computation.
Setup
To use this crate, add the following entry to your Cargo.toml
file in the dependencies
section:
[dependencies]
chksum-hash-sha2 = "0.0.1"
Alternatively, you can use the cargo add
subcommand:
cargo add chksum-hash-sha2
Usage
Use the hash
function for batch digest calculation.
use chksum_hash_sha2::sha2_256;
let digest = sha2_256::hash(b"example data");
assert_eq!(
digest.to_hex_lowercase(),
"44752f37272e944fd2c913a35342eaccdd1aaf189bae50676b301ab213fc5061"
);
Use the default
function to create a hash instance for stream digest calculation.
use chksum_hash_sha2::sha2_512;
let digest = sha2_512::default()
.update("example")
.update(b"data")
.update([0, 1, 2, 3])
.digest();
assert_eq!(
digest.to_hex_lowercase(),
"57f35477757af6734892604de3846a97d2cc17cd37068373075e56a4843b3e9c83f9b435beae9fcf1da590e73e62fe20468f52ff13b095241fec77884086b090"
);

Features
Cargo features are used to enable or disable specific algorithm functions.
224
enables SHA-2 224, accessible via thesha2_224
module,256
enables SHA-2 256, accessible via thesha2_256
module,384
enables SHA-2 384, accessible via thesha2_384
module,512
enables SHA-2 512, accessible via thesha2_512
module.
By default all of them are enabled.
To customize your setup, turn off the default features and enable only those that you want in your Cargo.toml
file:
[dependencies]
chksum-hash-sha2 = { version = "0.0.1", default-features = no, features = ["256", "512"] }
Alternatively, you can use the cargo add
subcommand:
cargo add chksum-hash-sha2 --no-default-features --features 256,512
