Detailed Description

template<class B = LittleEndian>
class Weak::PanamaHash< B >

Panama Hash

Definition at line 38 of file panama.h.

Member Function Documentation

template<class B = LittleEndian>
unsigned int Weak::PanamaHash< B >::DigestSize ( ) const
inlinevirtual

Provides the digest size of the hash.

Returns
the digest size of the hash.

Implements HashTransformation.

Definition at line 43 of file panama.h.

template<class B >
void Weak::PanamaHash< B >::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.
