Member Function Documentation

size_t SHA3_256::blockSize ( ) const

virtual

Size of the internal block used by the hash algorithm.

See Also

update(), hashSize()

Implements Hash.

Definition at line 55 of file SHA3.cpp.

void SHA3_256::clear ( )

virtual

Clears the hash state, removing all sensitive data, and then resets the hash ready for a new hashing process.

See Also

reset()

Implements Hash.

Definition at line 77 of file SHA3.cpp.

void SHA3_256::finalize ( void *  hash, size_t  len  )

virtual

Finalizes the hashing process and returns the hash.

Parameters

hash	The buffer to return the hash value in.
len	The length of the hash buffer, normally hashSize().

If len is less than hashSize(), then the hash value will be truncated to the first len bytes. If len is greater than hashSize(), then the remaining bytes will left unchanged.

If finalize() is called again, then the returned hash value is undefined. Call reset() first to start a new hashing process.

reset(), update()

Implements Hash.

Definition at line 70 of file SHA3.cpp.

size_t SHA3_256::hashSize ( ) const

virtual

Size of the hash result from finalize().

See Also

finalize(), blockSize()

Implements Hash.

Definition at line 50 of file SHA3.cpp.

void SHA3_256::reset ( )

virtual

Resets the hash ready for a new hashing process.

See Also

update(), finalize()

Implements Hash.

Definition at line 60 of file SHA3.cpp.

void SHA3_256::update ( const void *  data, size_t  len  )

virtual

Updates the hash with more data.

Parameters

data	Data to be hashed.
len	Number of bytes of data to be hashed.

If finalize() has already been called, then the behavior of update() will be undefined. Call reset() first to start a new hashing process.

reset(), finalize()
