Member Function Documentation

void DataBlockEncryptor::SetKey

(

const unsigned char

key[16]

)

Set the encryption key

Parameters:

[in]

key

The new encryption key

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

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

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

Returns:

False on bad checksum or input, true on success
