Authenticated AES Wrap Algorithm (RFC 3394:2002)

Description

Interface to authenticated AES wrap algorithm (RFC 3394:2002)

Functions
void	MODA_AES_WRAP_Encrypt (const struct aes_ctxt *aes, uint8_t *out, const uint8_t *in, uint16_t inSize, const uint8_t *iv)
	Wrap input. More...
bool	MODA_AES_WRAP_Decrypt (const struct aes_ctxt *aes, uint8_t *out, const uint8_t *in, uint16_t inSize, const uint8_t *iv)
	Unwrap input. More...

Function Documentation

bool MODA_AES_WRAP_Decrypt	(	const struct aes_ctxt *	aes,
		uint8_t *	out,
		const uint8_t *	in,
		uint16_t	inSize,
		const uint8_t *	iv
	)

Unwrap input.

Note

this process is able to validate correctness of out

inSize must be a multiple 8 and be equal to or greater than 16

out must be large enough to accomodate (inSize - 8) bytes

if in == out the process will be performed in place

the internal default IV shall be used if iv is set to NULL

Parameters

aes	block cipher expanded key
out	output buffer
in	input buffer
inSize	byte size of in
iv	8 byte IV field (NULL for default)

Returns

true if in unwrapped successfully

Examples:

test_aes_wrap.c.

void MODA_AES_WRAP_Encrypt	(	const struct aes_ctxt *	aes,
		uint8_t *	out,
		const uint8_t *	in,
		uint16_t	inSize,
		const uint8_t *	iv
	)

Wrap input.

Note

inSize must be a multiple 8 and be equal to or greater than 8

out must be large enough to accomodate inSize + 8 bytes

if in == out the process will be performed in place

the internal default IV shall be used if iv is set to NULL

Parameters

aes	block cipher expanded key
out	output buffer
in	input buffer
inSize	byte size of in
iv	8 byte IV field (NULL for default)

Examples:

test_aes_wrap.c.
