Method Detail

hexDigest

public static final String hexDigest(String id,
                                     String secret,
                                     String alg)
                              throws NoSuchAlgorithmException

This method encodes data using digest algorithm described in JEP-0078 documentation. As a result you have String containing digest data which can be compared with data sent by the user to authenticate him.

Parameters:

id - a String value of some ID value like session ID to concatenate with secret word.

secret - a String value of a secret word shared between entites.

alg - a String value of algorithm name to use for generating diffest message.

Returns:

a String value digest message as defined.

Throws:

NoSuchAlgorithmException - if an error occurs during encoding digest message.

digest

public static final byte[] digest(String id,
                                  String secret,
                                  String alg)
                           throws NoSuchAlgorithmException

Throws:

NoSuchAlgorithmException

bytesToHex

public static final String bytesToHex(byte[] buff)

$main

public static void $main(String[] args)
                  throws Exception

Describe main method here.

Parameters:

args - a String[] value

Throws:

Exception
