# 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](https://github.com/lucas-clemente/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=.
|
||
|
|
```
|
||
|
|
|
||
|
|
The output (on my machine):
