Function Documentation

void cham128_128_encrypt	(	const unsigned char *	key,
		unsigned char *	output,
		const unsigned char *	input
	)

Encrypts a 128-bit block with CHAM-128-128.

Parameters

key	Points to the 16 bytes of the key.
output	Output buffer which must be at least 16 bytes in length.
input	Input buffer which must be at least 16 bytes in length.

The input and output buffers can be the same buffer for in-place encryption.

void cham64_128_encrypt	(	const unsigned char *	key,
		unsigned char *	output,
		const unsigned char *	input
	)

Encrypts a 64-bit block with CHAM-64-128.

Parameters

key	Points to the 16 bytes of the key.
output	Output buffer which must be at least 8 bytes in length.
input	Input buffer which must be at least 8 bytes in length.

The input and output buffers can be the same buffer for in-place encryption.
