Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	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.
