http://www.unreadable.de/ takes a plaintext message + password input and encrypts the plaintext. I want to do this locally on Linux. Is there a one-line command that will compute an encrypted version of my message that I can then email?
My goal is for the receiver to be able to decode the message with nothing but the password.
To be clear, I have no idea what various encryption schemes are (AES, openSSL, RSA, GPG, salt, base64, DES, CBC, reentrant) and not really interested in a research project. I just want a one-line command like
encrypt message.txt -password=secret.txt
which would be decoded like
decrypt message.txt -password=secret.txt
(Yes, I did use google first. https://encrypted.google.com/search?q=encrypt+plain+text+files+with+password+linux is not showing me anything I understand / think I can use.)
