[−][src]Crate evpkdf
Rust implementation of OpenSSL EVP_bytesToKey function.
evpkdf
derives key from the given password and salt.
Notice that this approach is too weak for modern standard now. Newer applications should choice a more modern algorithm like bcrypt, pbkdf2 or scrypt.
Basic Usage
use evpkdf::evpkdf; use hex_literal::hex; use md5::Md5; // from md-5 crate use sha1::Sha1; // from sha-1 crate let mut output = []; evpkdf::<Md5>(b"password", b"saltsalt", 1000, &mut output); assert_eq!(output, []); let mut output = [0; 128 / 8]; evpkdf::<Md5>(b"password", b"saltsalt", 1000, &mut output); assert_eq!(output, hex!("8006de5d2a5d15f9bbdb8f40196d5af1")); let mut output = [0; 128 / 8]; evpkdf::<Sha1>(b"password", b"saltsalt", 1000, &mut output); assert_eq!(output, hex!("f8833429b112582447bc66f433497f75"));
Compatible with crypto-js
Below sinppet generates the same result as
CryptoJS.kdf.OpenSSL.execute('password', 256 / 32, 128 / 32, 'saltsalt')
.
use evpkdf::evpkdf; use hex_literal::hex; use md5::Md5; // from md-5 crate const KEY_SIZE: usize = 256; const IV_SIZE: usize = 128; let mut output = [0; (KEY_SIZE + IV_SIZE) / 8]; evpkdf::<Md5>(b"password", b"saltsalt", 1, &mut output); let (key, iv) = output.split_at(KEY_SIZE / 8); assert_eq!( key, hex!("fdbdf3419fff98bdb0241390f62a9db35f4aba29d77566377997314ebfc709f2") ); assert_eq!( iv, hex!("0b5ca7b1081f94b1ac12e3c8ba87d05a") );
