Function Documentation

void saturnin_decrypt_block	(	const saturnin_key_schedule_t *	ks,
		unsigned char *	output,
		const unsigned char *	input,
		unsigned	domain
	)

Decrypts a 256-bit block with Saturnin.

Parameters

ks	Points to the Saturnin key schedule.
output	Output buffer which must be at least 32 bytes in length.
input	Input buffer which must be at least 32 bytes in length.
domain	Domain separator and round count indicator.

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

void saturnin_encrypt_block	(	const saturnin_key_schedule_t *	ks,
		unsigned char *	output,
		const unsigned char *	input,
		unsigned	domain
	)

Encrypts a 256-bit block with Saturnin.

Parameters

ks	Points to the Saturnin key schedule.
output	Output buffer which must be at least 32 bytes in length.
input	Input buffer which must be at least 32 bytes in length.
domain	Domain separator and round count indicator.

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

void saturnin_setup_key	(	saturnin_key_schedule_t *	ks,
		const unsigned char *	key
	)

Sets up a key schedule for Saturnin.

Parameters

ks	Points to the key schedule to initialize.
key	Points to the 32 bytes of the key data.
