Method Details

getSaltedHash

public String getSaltedHash(String password)
                     throws SaltedHashException

Description copied from interface: SaltedHashService

Computes a salted hash of given plaintext password suitable for storing in a database.

Specified by:

getSaltedHash in interface SaltedHashService

Throws:

SaltedHashException

validate

public boolean validate(String password,
 String encodedSaltedHash)
                 throws SaltedHashException

Description copied from interface: SaltedHashService

Checks whether given plaintext password corresponds to the given saltedHash.

Specified by:

validate in interface SaltedHashService

Parameters:

password -

encodedSaltedHash -

Returns:

true if the given password matches the given saltedHash; false otherwise.

Throws:
