NAME

       kcapi_akcipher_setkey - set the private key for the cipher handle

SYNOPSIS

       int kcapi_akcipher_setkey(struct kcapi_handle * handle, const uint8_t * key,
                                 uint32_t keylen);

ARGUMENTS

       handle
           [in] cipher handle

       key
           [in] key buffer in DER format

       keylen
           [in] length of key buffer

DESCRIPTION

       With this function, the caller sets the key for subsequent cipher operations.

       The key must be in DER format as follows

       SEQUENCE { version INTEGER, n INTEGER ({ rsa_get_n }), e INTEGER ({ rsa_get_e }), d
       INTEGER ({ rsa_get_d }), prime1 INTEGER, prime2 INTEGER, exponent1 INTEGER, exponent2
       INTEGER, coefficient INTEGER }

       After the caller provided the key, the caller may securely destroy the key as it is now
       maintained by the kernel.

       return upon success the value of the maximum size for the asymmetric operation is returned
       (e.g. the modulus size); a negative errno-style error code if an error occurred
