Using SSH public key to encrypt a file or string
# Recently I had to send a password to someone over Skype. Since that's obviously not a good idea, I asked for
# the person's public SSH RSA key, and used it to encrypt the password itself.
# Convert the public key into PEM format
ssh-keygen -f path/to/id_rsa.pub -e -m pem > ~/id_rsa.pub.pem
# Using the public pem file to encrypt a string
echo "sometext" | openssl rsautl -encrypt -pubin -inkey ~/id_rsa.pub.pem > ~/encrypted.txt
