 *jrnl* is a simple journal application for your command line. Journals are stored as human readable plain text files - you can put them into a Dropbox folder for instant syncinc and you can be assured that your journal will still be readable in 2050, when all your fancy iPad journal applications will long be forgotten.
 
+Optionally, your journal can be encrypted using AES encryption

+### Encryption
+
+Should you ever want to decrypt your journal manually, you can do so with any program that supports the AES algorithm and the passwords you entered when running _jrnl_ for the first time. Since AES requires keys to be a multiple of 16 characters, passwords will be padded with trailing white spaces before using it to encrypt or decrypt your journal. Sow, if your password is `rosebud` (which I hope it isn't), the key with which to decrypt your journal is `rosebud_________` (the underscores represent whitespaces).
