Method Detail

createHash

public java.lang.String createHash(byte[] secret,
                          java.lang.Object salt)
                            throws HashingException

Description copied from interface: HashingService

Create a hash of the given data

Specified by:

createHash in interface HashingService

Parameters:

secret - The data

salt - A salt to use for hashing

Throws:

HashingException

checkPassword

public boolean checkPassword(byte[] secret,
                    java.lang.String hash)
                      throws HashingException

Description copied from interface: HashingService

Compares data to a previously created hash

Specified by:

checkPassword in interface HashingService

Parameters:

secret - The data

hash - The hash

Returns:

true if the data equals the data for which the hash was created

Throws:

HashingException

generateSalt

public java.lang.Object generateSalt()
                              throws HashingException

Description copied from interface: HashingService

Generates a salt to be used with the HashingService.createHash(byte[], Object) method. This is callable independently, so a functionality may use the same salt for multiple password hashings and then may test hash equality

Specified by:

generateSalt in interface HashingService

Throws:

HashingException

getName

public java.lang.String getName()

Description copied from interface: HashingService

Returns the name of this hashing scheme

Specified by:

getName in interface HashingService
