Function Documentation

◆ 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.

◆ mbedtls_pkcs5_pbkdf2_hmac()

int mbedtls_pkcs5_pbkdf2_hmac	(	mbedtls_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.
