SilcBool silc_pkcs_public_key_alloc(SilcPKCSType type,
                                        unsigned char *key,
                                        SilcUInt32 key_len
                                        SilcPublicKey *ret_public_key);

    Allocates SilcPublicKey of the type of `type' from the key data
    `key' of length of `key_len' bytes.  Returns FALSE if the `key'
    is malformed or unsupported public key type.  This function can be
    used to create public key from any kind of PKCS public keys that
    the implementation supports.
