aes12
This package modifies the AES-GCM implementation from Go's standard library to use 12 byte tag sizes. It is not intended for a general audience, and used in quic-go.
To make use of the in-place encryption / decryption feature, the dst parameter to Seal and Open should be 16 bytes longer than plaintext, not 12.
Command for testing:
go test . --bench=. && GOARCH=386 go test . --bench=.
