Class Tiger
- Cloneable, IMessageDigest
The Tiger message digest. Tiger was designed by Ross Anderson and Eli
Biham, with the goal of producing a secure, fast hash function that
performs especially well on next-generation 64-bit architectures, but
is still efficient on 32- and 16-bit architectures.
Tiger processes data in 512-bit blocks and produces a 192-bit
digest.

Tiger
public Tiger()
Trivial 0-arguments constructor.
getResult
protected byte[] getResult()
Constructs the result from the contents of the current context.
- getResult in interface BaseHash
- the output of the completed hash operation.
padBuffer
protected byte[] padBuffer()
Returns the byte array to use as padding before completing a hash
operation.
- padBuffer in interface BaseHash
- the bytes to pad the remaining bytes in the buffer before
completing a hash operation.
selfTest
public boolean selfTest()
A basic test. Ensures that the digest of a pre-determined message is equal
to a known pre-computed value.
- selfTest in interface IMessageDigest
- selfTest in interface BaseHash
true if the implementation passes a basic self-test.
Returns false otherwise.
transform
protected void transform(byte[] in,
int offset) The block digest transformation per se.
- transform in interface BaseHash
in - the blockSize long block, as an array of bytes to digest.offset - the index where the data to digest is located within the
input buffer.
