Specifies the functionality common to all Digest algorithms.
A digest algorithm is a function which converts an arbitrarily long input
data value to a fixed sized hash.

getAlgorithm()
Returns the name of this digest, for example "SHA1".
int
getBlockLength()
Returns the block length of the digest in bytes.
byte[]
getDigest()
Returns a byte array containing the digest of all the input data since
the last reset.
byte[]
getDigest(boolean resetDigest)
Returns a byte array containing the digest of all the input data since
the last reset.
int
getDigest(byte[] buffer,
int offset)
Inserts the digest of all the input data since the last reset
into the specified buffer at the given offset.
int
getDigest(byte[] buffer,
int offset,
boolean resetDigest)
Inserts the digest of all the input data since the last reset
into the specified buffer at the given offset.
int
getDigestLength()
Returns the length of the digest in bytes.
Returns the name of this digest, for example "SHA1".
Returns:
A String representing the name of the digest.

getBlockLength
public int getBlockLength()
Returns the block length of the digest in bytes.
Most digest algorithms are iterated hash functions, and thus process the input data in blocks.
Some primitives, like HMAC are sensitive to this block length.
Returns:
An integer representing the block length.

getDigest
public byte[] getDigest()
Returns a byte array containing the digest of all the input data since
the last reset. The digest is then reset.
Returns:
A byte array containing the digest.

getDigest
public byte[] getDigest(boolean resetDigest)
Returns a byte array containing the digest of all the input data since
the last reset.
Parameters:
resetDigest - if true, then the digest is reset.
Returns:
A byte array containing the digest.

getDigest
public int getDigest(byte[] buffer,
int offset)
Inserts the digest of all the input data since the last reset
into the specified buffer at the given offset.
The digest is then reset.
Parameters:
buffer - The byte array to hold the digest data.
offset - The offset, or initial bit position, to store the data at within the array.
Returns:
An integer representing the number of bytes written to the buffer.

into the specified buffer at the given offset.
Parameters:
buffer - The byte array to hold the digest data.
offset - The offset, or initial bit position, to store the data at within the array.
