public interface WSPasswordDigest

getPasswordDigest

byte[] getPasswordDigest(String username,
                         byte[] nonce,
                         String created)
                         throws DigestNotAvailableException

This method returns a digest based on the nonce, created date string and the corresponding password for the specified user. If the provider can not calculate the digest for a user because the provider has no knowledge of the user and/or the password for this user, then the provider should throw the DigestNotAvailableException exception

Parameters:

username - String containing the user name

nonce - Byte array to be used as a seed

created - String used to create the digest

Returns:

byte[] the digest created based on the users's password, nonce and the created string.

Throws:

DigestNotAvailableException - if the password digest could not be created

getDerivedKey

byte[] getDerivedKey(String username,
                     byte[] salt,
                     int iteration)
                     throws DigestNotAvailableException

Returns the derived key. The derived key is generated based on the user's password and the salt. The iteration count decides how many times the derived key value is successively encrypted to generate the final derived key value.

Parameters:

username - String containing the user name.

salt - Byte array to be used as a seed

iteration - int number of times the derived key value is successively encrypted to generate the final derived key value.

Returns:

byte[] the final derived key value based on the password and salt

Throws:

DigestNotAvailableException
