Function dryoc::classic::crypto_pwhash::crypto_pwhash

pub fn crypto_pwhash(
    output: &mut [u8],
    password: &[u8],
    salt: &[u8],
    opslimit: u64,
    memlimit: usize,
    algorithm: PasswordHashAlgorithm
) -> Result<(), Error>

Hashes password with salt, placing the resulting hash into output.

• opslimit specifies the number of iterations to use in the underlying algorithm
• memlimit specifies the maximum amount of memory to use, in bytes

Generally speaking, you want to set opslimit and memlimit sufficiently large such that it’s hard for someone to brute-force a password.

For your convenience, the following constants are defined which can be used with opslimit and memlimit:

• CRYPTO_PWHASH_OPSLIMIT_INTERACTIVE and CRYPTO_PWHASH_MEMLIMIT_INTERACTIVE for interactive operations
• CRYPTO_PWHASH_OPSLIMIT_MODERATE and CRYPTO_PWHASH_MEMLIMIT_MODERATE for typical operations, such as server-side password hashing
• CRYPTO_PWHASH_OPSLIMIT_SENSITIVE and CRYPTO_PWHASH_MEMLIMIT_SENSITIVE for sensitive operations

Compatible with libsodium’s crypto_pwhash.
