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
