bool DataBlockEncryptor::Decrypt	(	unsigned char *	input,
		unsigned int	inputLength,
		unsigned char *	output,
		unsigned int *	outputLength
	)

Decryption removes bytes, as few as 6.

Output should be large enough to hold this. Output can be the same memory block as input

Parameters:

`[in]`	input	the input buffer to decrypt
`[in]`	inputLength	the size of the input buffer
`[in]`	output	the output buffer to store decrypted data
`[in]`	outputLength	the size of the output buffer

void DataBlockEncryptor::Encrypt	(	unsigned char *	input,
		unsigned int	inputLength,
		unsigned char *	output,

Encryption adds 6 data bytes and then pads the number of bytes to be a multiple of 16.

Output should be large enough to hold this. Output can be the same memory block as input

Parameters:

`[in]`	input	the input buffer to encrypt
`[in]`	inputLength	the size of the input buffer
`[in]`	output	the output buffer to store encrypted data
`[in]`	outputLength	the size of the output buffer
