Member Function Documentation

virtual Retval zeus::TAbstractCrypter::encode	(	const IByteArray &	rInput,
		IByteArray &	rOutput
	)			[pure virtual]

encodes a clear text into a cipher text. This method takes an input array of size from getBlockSizeForEncoding(). Each crypting algorithm might need a different input size (8bit or 64bit blocks, ...). The output array contains the cipher text (size of getBlockSizeForDecoding() bytes.

Parameters:

	rInput	: Clear text input
	rOutput,:	Cipher text output

Return values:

	RET_NOERROR	: Text encoded
	RET_REQUEST_FAILED	: Could not encode the text. The block size of the clear text might be wrong

Implemented in zeus::TBlockCipherXTEA, zeus::TSimpleDES, and TStandardZipEncryption.

virtual Retval zeus::TAbstractCrypter::decode	(	const IByteArray &	rInput,
		IByteArray &	rOutput
	)			[pure virtual]

encodes a cypher text into a clear text. This method takes an input array of size from getBlockSizeForDecoding().

Parameters:

	rInput	: Cipher text input
	rOutput,:	Clear text output

Return values:

	RET_NOERROR	: Text encoded
	RET_REQUEST_FAILED	: Could not encode the text. The block size of the cipher text might be wrong

Implemented in zeus::TBlockCipherXTEA, zeus::TSimpleDES, and TStandardZipEncryption.
