Method Details

hash

public static Optional<String> hash(String password,
 byte[] saltBytes)

Hashes a password using the Argon2 algorithm with the provided salt and default parameters.

Parameters:

password - The password to hash.

saltBytes - The salt to use for hashing.

Returns:

An Optional containing the encoded hash if successful, or an empty Optional if an error occurs.

hash

public static Optional<String> hash(String password,
 byte[] saltBytes,
 int nIterations,
 int kibMemoryCost)

Hashes a password using the Argon2 algorithm with the provided parameters.

Parameters:

password - The password to hash.

saltBytes - The salt to use for hashing.

nIterations - The number of iterations to perform.

kibMemoryCost - The memory cost in KiB.

Returns:

An Optional containing the encoded hash if successful, or an empty Optional if an error occurs.

verify

public static boolean verify(String password,
 String encodedHash)

Verifies a password against an encoded hash.

Parameters:

password - The password to verify.

encodedHash - The encoded hash to compare against.

Returns:

True if the password matches the hash, false otherwise.
