IMessageDigestA basic test. Ensures that the digest of a pre-determined message is equal to a known pre-computed value.
selfTest in interface IMessageDigestselfTest in class BaseHashprotected byte[] padBuffer()
Generates an array of padding bytes. The padding is defined as
i bytes of value i, where i is the
number of bytes to fill the last block of the message to
BLOCK_LENGTH bytes (or BLOCK_LENGTH bytes when
the last block was completely full).
