# sshencdec.sh

bash script to encrypt data using a users ssh public key.

> If you received a message from someone that was encrypted with this script, you can
> just use openssl to decrypt it, without the need to download this script:

```
(openssl base64 -d | openssl rsautl -decrypt -inkey ~/.ssh/id_rsa) < file-containing-the-encrypted-text.txt
```

## examples

### encrypt a file using your own ssh public key
```
./sshencdec.sh -p ~/.ssh/id_rsa.pub < plain-text-file.txt > encrypted.txt
```

### encrypt a file using the public key of a github user
```
./sshencdec.sh -p <(curl -sf "https://github.com/S2-.keys" | head -n1) < plain-text-file.txt
```

this line fetches the first public key for the github user `S2-` and encrypts the file `plain-text-file.txt` using this key.

### decrypt a file
```
./sshencdec.sh -s ~/.ssh/id_rsa < encrypted.txt
```
