Member Function Documentation

Retval TSecureHash512::generate	(	const IByteArray &	rInput,
		IByteArray &	rOutput
	)		[protected, virtual]

Generates the secure hash out a input char-array

See also:

TAbstractHash::generate

Implements zeus::TAbstractHash.

void TSecureHash512::getHMAC	(	const IByteArray &	rKey,
		const IByteArray &	rInput,
		IByteArray &	rOutput
	)

returns the hash-based Message authenication code for SHA512-based hash algorithms

Parameters:

rKey	: secret key
rInput	: message to hash
rOutput	: out put of the generated authenication code

Return values:

RET_NOERROR	: authenication code generated
RET_INTERNAL_ERROR	: internal error (block size unknown)
