Method Detail

NESSIEinit

public void NESSIEinit()

Initialize the hashing state.

NESSIEadd

public void NESSIEadd(byte[] source,
                      long sourceBits)

Delivers input data to the hashing algorithm.

Parameters:

source - plaintext data to hash.

sourceBits - how many bits of plaintext to process. This method maintains the invariant: bufferBits < 512

NESSIEfinalize

public void NESSIEfinalize(byte[] digest)

Get the hash value from the hashing state. This method uses the invariant: bufferBits < 512

NESSIEadd

public void NESSIEadd(java.lang.String source)

Delivers string input data to the hashing algorithm.

Parameters:

source - plaintext data to hash (ASCII text string). This method maintains the invariant: bufferBits < 512

getHash

public java.lang.String getHash(java.lang.String password,
                                java.lang.String salt,
                                java.lang.String name)
                         throws java.security.NoSuchAlgorithmException

Specified by:

getHash in interface EncryptionMethod

salt - (can be an other data like playerName;salt , playerName, etc... for customs methods)

Returns:

Hashing password

Throws:

java.security.NoSuchAlgorithmException

comparePassword

public boolean comparePassword(java.lang.String hash,
                               java.lang.String password,
                               java.lang.String playerName)
                        throws java.security.NoSuchAlgorithmException

Specified by:

comparePassword in interface EncryptionMethod

Returns:

true if password match, false else

Throws:

java.security.NoSuchAlgorithmException
