type Salt a = SizedByteArray CRYPTO_PWHASH_SALTBYTES a

Salt used for password hashing.

This type is parametrised by the actual data type that contains bytes. This can be, for example, a ByteString.

pwhash

Arguments

:: forall passwd salt n hash. (ByteArrayAccess passwd, ByteArrayAccess salt, ByteArrayN n hash, CRYPTO_PWHASH_BYTES_MIN <= n, n <= CRYPTO_PWHASH_BYTES_MAX)

=> Algorithm

Hashing algorithm.

-> Params

Hashing parameters.

-> passwd

Password to hash.

-> Salt salt

Hashing salt.

-> IO (Maybe hash)

Securely hash a password.

This is crypto_pwhash, it can be used for key derivation.
