void update(byte b) Function

Updates the hash being computed with a single byte.

void update(byte[]buf, int offset, int length) Function

Update the hash being computed with length of the bytes in buf starting at offset. The programmer should ensure that buf is at least offset + length bytes long.

byte [] digest () Function

Finishes the computation of the hash and returns the result as a byte array. The input read thusfar may be padded first (depending on the algorithm), and the instance is reset.

java.lang.String name() Function

Returns the canonical name of this message digest.

int hashSize() Function

Returns the size of the final hash (the byte array returned by digest()) in bytes.

int blockSize() Function

Returns the algorithm's internal block size, in bytes.

void reset() Function

Resets the internal state of the hash, making its state equivalent to that of a newly-created instance.

boolean selfTest() Function

Performs a simple conformance test of the underlying implementation, to guard against implementation or environment errors. Returns true if the test succeeds, false if it fails.

java.lang.Object clone() Function

Copies the state of this instance into a new instance, returning the copy. This copy can then be used in the same way as the original instance.
