# AES/GCM min sample
This is an attempt of producing a sane and well-explained tiny code to show how to use (minimally)
``AES-256/GCM`` into ``Linux kernel crypto api``. Instead of wasting hours grasping into code that
does not matter directly to your task.
I have waste some time on it and I hope you waste less of your time from now on.

Have you found issues? Please, let me [know](https://github.com/rafael-santiago/linux-crypto-api-aes-gcm-min-sample/issues) and
thank you!
## How can I clone it?
```
_ git clone https://github.com/rafael-santiago/linux-crypto-api-aes-gcm-min-sample
```
All code is within ``src`` subdirectory.
## How can I build?
```
cd src
make
```
If the build has succeeded you will got ``aes-gcm-min-sample.ko`` module.
## How can I test it?
It is just about inserting the produced ``LKM``. Supposing your ``cwd`` is the ``src`` subdirectory:
```
_ insmod ./aes-gcm-min-sample.ko
```
Watch the results by executing ``dmesg``.
If the encryption and decryption was done, the kernel module has inserted, so you need to remove it:
```
_ rmmod aes-gcm-min-sample
```
So folks, that's all!
I hope it be useful and saves your time ;)
