Member Function Documentation

void Tiger::TruncatedFinal ( byte *  digest,
size_t  digestSize 
)
virtual

Computes the hash of the current message.

Parameters
digesta pointer to the buffer to receive the hash
digestSizethe size of the truncated digest, in bytes

TruncatedFinal() call Final() and then copies digestSize bytes to digest

TruncatedFinal() restarts the hash for the next message.

Precondition
COUNTOF(digest) == DigestSize() or COUNTOF(digest) == HASH::DIGESTSIZE ensures the output byte buffer is large enough for the digest.

Implements HashTransformation.
