mbedtls_pkcs12_derivation()

int mbedtls_pkcs12_derivation	(	unsigned char *	data,
		size_t	datalen,
		const unsigned char *	pwd,
		size_t	pwdlen,
		const unsigned char *	salt,
		size_t	saltlen,
		mbedtls_md_type_t	mbedtls_md,
		int	id,
		int	iterations
	)

The PKCS#12 derivation function uses a password and a salt to produce pseudo-random bits for a particular "purpose".

Depending on the given id, this function can produce an encryption/decryption key, an nitialization vector or an integrity key.

Parameters

data	buffer to store the derived data in
datalen	length to fill
pwd	password to use (may be NULL if no password is used)
pwdlen	length of the password (may be 0)
salt	salt buffer to use
saltlen	length of the salt
mbedtls_md	mbedtls_md type to use during the derivation
id	id that describes the purpose (can be MBEDTLS_PKCS12_DERIVE_KEY, MBEDTLS_PKCS12_DERIVE_IV or MBEDTLS_PKCS12_DERIVE_MAC_KEY)
iterations	number of iterations

Returns

0 if successful, or a MD, BIGNUM type error.

		unsigned char *	output
	)

PKCS12 Password Based function (encryption / decryption) for cipher-based and mbedtls_md-based PBE's.

Parameters

pbe_params	an ASN1 buffer containing the pkcs-12PbeParams structure
mode	either MBEDTLS_PKCS12_PBE_ENCRYPT or MBEDTLS_PKCS12_PBE_DECRYPT
cipher_type	the cipher used
md_type	the mbedtls_md used
pwd	the password used (may be NULL if no password is used)
pwdlen	length of the password (may be 0)
input	the input data
len	data length
output	the output buffer

Returns

0 if successful, or a MBEDTLS_ERR_XXX code
