bash script to encrypt data using a users ssh public key.
@@ -6,35 +6,35 @@ bash script to encrypt data using a users ssh public key.
> decrypt it with your ssh private key using the following command:
```
./sshencdec.sh -s ~/.ssh/id_rsa < file-containing-the-encrypted-text.txt
./sshenc.sh -s ~/.ssh/id_rsa < file-containing-the-encrypted-text.txt
```
## install
```
wget https://git.e.tern.al/s2/sshencdec/raw/branch/master/sshencdec.sh
chmod +x sshencdec.sh
wget wget https://sshenc.sh/sshenc.sh
chmod +x sshenc.sh
```
## examples
### encrypt a file using your own ssh public key
```
./sshencdec.sh -p ~/.ssh/id_rsa.pub < plain-text-file.txt > encrypted.txt
./sshenc.sh -p ~/.ssh/id_rsa.pub < plain-text-file.txt > encrypted.txt
```
### encrypt a file using multiple recipients (broadcast encryption)
```
./sshencdec.sh -p ~/.ssh/id_rsa.pub -p id_rsa-alice.pub -p id_rsa-bob.pub < plain-text-file.txt > encrypted.txt
./sshenc.sh -p ~/.ssh/id_rsa.pub -p id_rsa-alice.pub -p id_rsa-bob.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" | grep ssh-rsa | tail -n1) < plain-text-file.txt
./sshenc.sh -p <(curl -sf "https://github.com/S2-.keys" | grep ssh-rsa | tail -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
./sshenc.sh -s ~/.ssh/id_rsa < encrypted.txt
```
