title: Decrypting files with a program different from what it was encrypted with
body: <p>as the title says, I just have the very basic question of whether or not a file (let's say a txt file in this case) can be decrypted using a program that it wasn't encrypted with?</p>
  
  <p>For instance if I encrypted a txt files with GPG, could I decrypt it with AES Crypt or openssl?</p>
  
  <p>Thanks for the insight.</p>
