Detailed Description

Pyjamask block cipher.

Function Documentation

void pyjamask_128_decrypt	(	const pyjamask_128_key_schedule_t *	ks,
		unsigned char *	output,
		const unsigned char *	input
	)

Decrypts a 128-bit block with Pyjamask-128.

Parameters

ks	Points to the key schedule.
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 decryption.
