Method Detail

load

static HashingStrategy load()

Factory method to load the algorithms from the system

Returns:

a Hashing Strategy capable of hashing using the available algorithms

hash

String hash(String id,
            Map<String,String> params,
            String salt,
            String password)

Hashes a password.

Parameters:

id - the algorithm id

params - the algorithm specific parameters

salt - the given salt

password - the given password

Returns:

the hashed string

verify

boolean verify(String hash,
               String password)

Time constant password check. Regardless of the check, this algorithm executes the same number of checks regardless of the correctly number of characters

Parameters:

hash - the hash to verify

password - the password to test against

Returns:

boolean

get

HashingAlgorithm get(String id)

Get an algorithm interface by its Id

Parameters:

id - the algorithm id

Returns:

the algorithm

put

HashingStrategy put(String id,
                    HashingAlgorithm algorithm)

Put or replace an algorithm into the list of system loaded algorithms.

Parameters:

id - the algorithm id

algorithm - the implementation

Returns:
