## Message

```
Be more conservative in the description of Aegis256Mac (#16452)

It is assumed that generating a collision requires more than 2^156
ciphertext modifications. This is plenty enough for any practical
purposes, but it hasn't been proven to be >= 2^256.

Be consistent and conservative here; just claim the same security
as the other variants.
```
