Method Detail

parseResponse

public static HashMap<String,byte[]> parseResponse(byte[] challenge,
                                                         Charset charset,
                                                         boolean multiRealm,
                                                         ElytronMessages log)
                                                  throws AuthenticationMechanismException

Client side method to parse challenge sent by server.

Parameters:

challenge - the byte array representing the authentication challenge to be parsed.

charset - the charset to decide which whitespace separator is used.

multiRealm - true if there are multiple realms in the challenge, false otherwise

log - the logger to use.

Returns:

A new HashMap representing response for the parsed challenge

Throws:

AuthenticationMechanismException - if there is an error parsing the challenge

userRealmPasswordDigest

public static byte[] userRealmPasswordDigest(MessageDigest messageDigest,
                                             String username,
                                             String realm,
                                             char[] password)

Digests the concatenated username, realm and password.

Parameters:

messageDigest - the message digest algorithm to use when computing the digest.

username - the username to use when concatenating.

realm - the realm to use when concatenating.

password - the password in the form of a char array to use when concatenating.

Returns:

byte array of the digested password.

getTwoWayPasswordChars

public static char[] getTwoWayPasswordChars(TwoWayPassword password,
                                            Supplier<Provider[]> providers,
                                            ElytronMessages log)
                                     throws AuthenticationMechanismException

Get array of password chars from TwoWayPassword.

Parameters:

password - the TwoWayPassword that needs to be processed.

providers - the supplier for the providers to be used for processing.

log - the logger to use.

Returns:

encoded password in the form of a char array.

Throws:

AuthenticationMechanismException - if there is an error retrieving the encoded password.
