Function Documentation

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.

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 in bytes
output	Generated key. Must be at least as big as key_length

Returns

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