Fluent Hash

fluent-hash is a wrapper on top of the ring cryptography library which provides a fluent interface for generating SHA-1 and SHA-2 hashes.

It provides convenience methods for generating hashes from the following types:

• &[u8]
• Vec<u8>
• &str
• std::fs::File

It also supports formatting hashes as bytes or hexadecimal.

Supported Hash Algorithms

The following SHA-1 and SHA-2 algorithms are supported:

• SHA-1
• SHA-256
• SHA-384
• SHA-512
• SHA-512_256

Documentation

See the documentation at: https://docs.rs/fluent-hash/

Examples

Import the fluent_hash types.

use fluent_hash::Hashing::Sha1;
use fluent_hash::Hashing::Sha256;
use fluent_hash::Hashing::Sha384;
use fluent_hash::Hashing::Sha512;
use fluent_hash::Hashing::Sha512_256;
use fluent_hash::Hashing;
use fluent_hash::HashContext;
use fluent_hash::Hash;

Hash a byte array.

let result: Hash = Sha256.hash(b"hello, world");

Hash a byte vector.

let result: Hash = Sha256.hash_vec(b"hello, world".to_vec());

Hash a string.

let result: Hash = Sha256.hash_str("hello, world");

Hash a file.

let result: Hash = Sha256.hash_file("file.txt")?;

Format the hash.

let bytes: &[u8] = result.as_bytes();
let bytes_vec: Vec<u8> = result.to_vec();
let hex: String = result.to_hex();
