AES KWP unwrapping.

Parameters

[out]	pt	Plaintext. Buffer length >= ct_len - 8.
[out]	pt_len	Plaintext length, ct_len - 16 < pt_len <= ct_len - 8.
	ct	Ciphertext.
	ct_len	Ciphertext length, ct_len = n * 8, n >= 2.
	key	AES key.
	size	Key size (16, 24, or 32).

Return values

0	If ct is valid.
-1	Otherwise.
