Octavo

Highly modular & configurable hash & crypto library written in pure Rust.

Installation

[dependencies]
octavo = { git = "https://github.com/libOctavo/octavo" }

WARNING!!! Octavo is in very early stage of development. There is a hell lot of issues and vulnerabilities to enormous kind of attacks! Do not use it in production code (yet)!

Cryptographic hash functions primitives

Via Wikipedia:

The ideal cryptographic hash function has four main properties:

• it is easy to compute the hash value for any given message
• it is infeasible to generate a message from its hash
• it is infeasible to modify a message without changing the hash
• it is infeasible to find two different messages with the same hash.

Example

Calculate SHA-512 sum:

use octavo_digest::Digest;
use octavo_digest::sha2::Sha512;

let mut result = vec![0; Sha512::output_bytes()];
let mut sha = Sha512::default();

sha.update(data);
sha.result(&mut result);

for byte in result {
    print!("{:2x}", byte);
}
println!(" {}", data);
