Function Documentation

int pbkdf2_hmac	(	md_context_t *	ctx,
		const unsigned char *	password,
		size_t	plen,
		const unsigned char *	salt,
		size_t	slen,
		unsigned int	iteration_count,
		uint32_t	key_length,
		unsigned char *	output
	)

PKCS#5 PBKDF2 using HMAC.

Deprecated:

Use pkcs5_pbkdf2_hmac() instead

Parameters

ctx	Generic HMAC context
password	Password to use when generating key
plen	Length of password
salt	Salt to use when generating key
slen	Length of salt
iteration_count	Iteration count
key_length	Length of generated key
output	Generated key. Must be at least as big as key_length

Returns

0 on success, or a POLARSSL_ERR_xxx code if verification fails.

int pbkdf2_self_test

(

int

verbose

)

Checkup routine.

Deprecated:

Use pkcs5_self_test() instead

Returns

0 if successful, or 1 if the test failed
