Method Summary

Methods

Modifier and Type	Method and Description
String	getDigestAlgorithmName()
int	getDigestSize()
Digest	getInstance()
Digest	getInstance(byte[] encoded) Create a new initialized digest from serialized encoding.
Digest	getInstance(DigestParameters parameters) This is a very usual need, since most digest does not take parameters, but this will allow digest that take parameters to be implemented as well.

Method Detail

getDigestAlgorithmName

String getDigestAlgorithmName()

Returns:

the algorithm name of created ciphers (ie: AES, CAST5, ...)

getDigestSize

int getDigestSize()

Returns:

the block size of created ciphers (in bytes).

getInstance

Digest getInstance()

Returns:

an initialized digest ready to process data.

getInstance

Digest getInstance(DigestParameters parameters)

This is a very usual need, since most digest does not take parameters, but this will allow digest that take parameters to be implemented as well.

Parameters:

parameters - digest parameters to initialize the digest.

Returns:

an initialized digest ready to process data based on given parameters.

getInstance

Digest getInstance(byte[] encoded)

Create a new initialized digest from serialized encoding.

Parameters:

encoded - encoded parameters to initialize this digest.

Returns:

an initialized digest ready to process data based on encoded data.
