Day36:Calculate sha1 with crypto and sha1 crate - 100DayOfRust

Posted on February 23, 2020
There are 2 crates you can use to calculate the sha1 value: crypto and sha1:
Cargo.toml:
[dependencies]
rust-crypto = "0.2.36"
sha1 = "0.6.0"
Example code:
use crypto;
use crypto::digest::Digest;
use sha1;
fn main() {
// use crypto crate to get sha1 hexdigest
let s = "hello world";
let mut hasher1 = crypto::sha1::Sha1::new();
hasher1.input_str(s);
let hex1 = hasher1.result_str();
println!("digest: {}", hex1);
// use sha1 crate to get sha1 hexdigest, simpler
let hex2 = sha1::Sha1::from(s).digest();
println!("digest: {}", hex2);
}
Cargo run:
digest: 2aae6c35c94fcfb415dbe95f408b9ce91ee846ed
digest: 2aae6c35c94fcfb415dbe95f408b9ce91ee846ed
To calculate other digest like md5, sha256 or hmac, you can check my previous post here.
