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 decrypt it with your ssh private key using the following command:

./sshencdec.sh -s ~/.ssh/id_rsa < file-containing-the-encrypted-text.txt

install

wget https://git.e.tern.al/s2/sshencdec/raw/master/sshencdec.sh
chmod +x sshencdec.sh

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 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

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
