Hi everyone.

Has anyone here worked with aes-gcm? As far as I understand, when using encrypt_in_place / decrypt_in_place, I’m required to implement the Buffer trait only because the library can’t tell in advance whether there’s enough space for the authentication tag during encryption.

Isn’t that just bad design? It forces me to inject a buffer pool into the object implementing Buffer, just to avoid unnecessary allocations - instead of simply allowing me to pass a &mut [u8] with enough capacity upfront.
