Detailed Description

SPECK-64 block cipher.

Function Documentation

void speck64_128_encrypt	(	const unsigned char *	key,
		unsigned char *	output,
		const unsigned char *	input
	)

Encrypts a 64-bit block with SPECK-64-128 in COMET byte order.

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.

Note

This version expects the key, input, and output to be in little-endian byte order, as expected by the COMET specification.
