# goaes

`goaes` is a very simple tool for encrypting files with AES-256 GCM.

## about

I wanted to write some Go and encryption fascinates me, so I wrote `goaes`.

### what it is

- it's a fun project
- it uses [key wrapping](https://en.wikipedia.org/wiki/Key_wrap)
- it's fast
- it's simple

### what it isn't

- it's not meant for production
- it's not meant for sensitive data
- it's not secure

## getting started

1. Generate a new passphrase.
2. Generate a new salt.

```bash
goaes generate
```

Don't use these. These are mine.

```bash
XGfpiNUvKJy8k7KeUEyhev4jkTIajb1s9CMJP9xH/7A=
tjrXXdH+0/NXSsaDOYuGtEM2zXxWFNPXSPXoli5++iE=
```

3. Set `GOAES_PASSPHRASE` to the passphrase.
4. Set `GOAES_SALT` to the salt.
5. Run the `goaes` command.

```bash
export GOAES_PASSPHRASE=XGfpiNUvKJy8k7KeUEyhev4jkTIajb1s9CMJP9xH/7A=
export GOAES_SALT=tjrXXdH+0/NXSsaDOYuGtEM2zXxWFNPXSPXoli5++iE=

goaes encrypt -s ./input.txt -d ./output.enc
```
