NAME

       kcapi_pbkdf - 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
