Member Function Documentation

hash()

PasswordHash dev.rafex.ether.crypto.password.PasswordHasherPBKDF2.hash	(	final char[]	password,
		final byte[]	salt,
		final int	iterations )

Hashes a password using PBKDF2-HMAC-SHA256.

Parameters

password	The password to hash.
salt	The random salt bytes.
iterations	The number of PBKDF2 iterations.

Returns

The resulting PasswordHash.

Exceptions

IllegalArgumentException

if password is null, salt is null or empty, or iterations is not positive.

		final int	iterations,
		final byte[]	expectedHash )

Verifies a password against an expected hash using PBKDF2-HMAC-SHA256.

Parameters

password	The password to verify.
salt	The random salt bytes.
iterations	The number of PBKDF2 iterations.
expectedHash	The expected hash bytes.
