Function Documentation

aes128_enc()

void aes128_enc	(	void *	buffer,
		aes128_ctx_t *	ctx
	)

encrypt with 128 bit key.

This function encrypts one block with the AES algorithm under control of a keyschedule produced from a 128 bit key.

Parameters

buffer	pointer to the block to encrypt
ctx	pointer to the key schedule

Definition at line 126 of file aes_enc.c.

aes192_enc()

void aes192_enc	(	void *	buffer,
		aes192_ctx_t *	ctx
	)

encrypt with 192 bit key.

This function encrypts one block with the AES algorithm under control of a keyschedule produced from a 192 bit key.

Parameters

buffer	pointer to the block to encrypt
ctx	pointer to the key schedule

Definition at line 131 of file aes_enc.c.

aes256_enc()

void aes256_enc	(	void *	buffer,
		aes256_ctx_t *	ctx
	)

encrypt with 256 bit key.

This function encrypts one block with the AES algorithm under control of a keyschedule produced from a 256 bit key.

Parameters

buffer	pointer to the block to encrypt
ctx	pointer to the key schedule
