AES-GCM encryption.

Parameters

[out]	ct	Ciphertext.
[out]	tag	Authentication tag.
	tag_len	Authentication tag length, 0 < tag_len <= 16.
	pt	Plaintext.
	pt_len	Plaintext length, 0 < ct_len < 2^36-32 bytes.
	key	AES key.
	size	Key size (16, 24, or 32 bytes).
	iv	Initial vector.
	aa	Additional authentication data.
	aa_len	Additional authentication data length, 0 < aa_len < 2^61 bytes.

Remarks

ct may be same as pt.
