# ![sshenc.sh](logo.png) **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 decrypt it with your ssh private key using the following command without installing anything: ``` bash <(curl -s https://sshenc.sh/sshenc.sh) -s ~/.ssh/id_rsa < file-containing-the-encrypted-text.txt ``` sshenc.sh uses openssl under the hood, so you need to have that installed in your path to make it work. ## Install ``` curl -O https://sshenc.sh/sshenc.sh chmod +x sshenc.sh ``` ## Examples ### encrypt a file using your own ssh public key ``` sshenc.sh -p ~/.ssh/id_rsa.pub < plain-text-file.txt > encrypted.txt ``` ### encrypt a file using multiple recipients (broadcast encryption) ``` 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 ``` 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 ``` sshenc.sh -s ~/.ssh/id_rsa < encrypted.txt ``` ## License [MIT](https://opensource.org/licenses/MIT)
