Rose::Combinatorics::HasherGcrypt< hashAlgorithmId > Class Template Reference

Description

template<int hashAlgorithmId>
class Rose::Combinatorics::HasherGcrypt< hashAlgorithmId >

Hasher for any libgcrypt hash algorithm.

The hashAlgorithmId template parameter is one of the libgcrypt algorithm constants (type int) with a name starting with "GCRY_MD_". You can find a list here.

clear()

template<int hashAlgorithmId>

void Rose::Combinatorics::HasherGcrypt< hashAlgorithmId >::clear ( )

Reset the hasher to its initial state.

digest()

template<int hashAlgorithmId>

const Digest & Rose::Combinatorics::HasherGcrypt< hashAlgorithmId >::digest ( )

inlinevirtual

Return the digest.

Finalizes the hash function and returns the digest for all the input. Additional input should not be inserted after this function is called since some hash functions don't support this.

Reimplemented from Rose::Combinatorics::Hasher.

Definition at line 414 of file Combinatorics.h.

References Rose::Combinatorics::Hasher::digest().

append()

template<int hashAlgorithmId>

void Rose::Combinatorics::HasherGcrypt< hashAlgorithmId >::append ( const uint8_t *  message, size_t  messageSize  )

inlinevirtual

Insert data into the digest.

This is the lowest level method of inserting new message content into the digest. This can be called as often as desired, building a digest incrementally.

Implements Rose::Combinatorics::Hasher.
