Detailed Description

Tiger message digest.

Crypto++ provides the original Tiger hash that was submitted to the NESSIE project. The implementation is different from the revised Tiger2 hash.

Member Function Documentation

◆ InitState()

void Tiger::InitState ( HashWordType *  state)
static

Initialize state array.

Parameters
statethe state of the hash

Definition at line 30 of file tiger.cpp.

◆ Transform()

void Tiger::Transform ( word64 digest,
const word64 data 
)
static

Operate the hash.

Parameters
digestthe state of the hash
datathe data to be digested

Definition at line 54 of file tiger.cpp.

◆ TruncatedFinal()

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

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() calls Final() and then copies digestSize bytes to digest. The hash is restarted the hash for the next message.
