mbedtls_pkcs5_pbes2()

int mbedtls_pkcs5_pbes2	(	const mbedtls_asn1_buf *	pbe_params,
		int	mode,
		const unsigned char *	pwd,
		size_t	pwdlen,
		const unsigned char *	data,
		size_t	datalen,
		unsigned char *	output
	)

PKCS#5 PBES2 function.

Parameters

pbe_params	the ASN.1 algorithm parameters
mode	either MBEDTLS_PKCS5_DECRYPT or MBEDTLS_PKCS5_ENCRYPT
pwd	password to use when generating key
pwdlen	length of password
data	data to process
datalen	length of data
output	output buffer

Returns

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

slen	Length of salt
iteration_count	Iteration count
key_length	Length of generated key in bytes
output	Generated key. Must be at least as big as key_length
