kcapi_pbkdf - Man Page
Password-based Key Derivation Function
Synopsis
ssize_t kcapi_pbkdf(const char * hashname, const uint8_t * pw, uint32_t pwlen, const uint8_t * salt, size_t saltlen, uint32_t count, uint8_t * key, size_t keylen);
Arguments
hashname
[in] kernel crypto API name of a keyed hash (e.g. hmac(sha1))
pw
[in] Password a key shall be derived from
pwlen
[in] Length of password string
salt
[in] Salt as defined in SP800-132
saltlen
[in] Length of salt buffer
count
[in] Numbers of iterations to be performed for the PBKDF
key
[out] Buffer to store the generated key in
keylen
[in] Size of the key to be generated (i.e. length of the key buffer)
Description
This function is an implementation of the PBKDF as defined in SP800-132.
return 0 upon success; a negative errno-style error code if an error occurred
