title: Encrypt and decrypt files with password
body: <p>I'm using linux and I basically want to encrypt a file using a password.</p>
  
  <p>I've tried using <code>gpg -c myfile</code> for encryption, and that works fine, it asks me for a password and encrypts it. But it only asks for a password when encrypting.</p>
  
  <p>I want a way to encrypt a file and if you want to decrypt it you have to give the same password that it was encrypted with.</p>
  
  <hr>
  
  <p>If there's a python library that would work too since I can put that on a script.</p>
