Once launched, here is the very first screen it will show you. Just like a text editor, it has a menu bar on the top and you can perform all operations from there.
First of all, lets generate a key and passphrase which we will use for all future encryption/decryption tasks. Click Encryption > Generate Key option from top menu and here is the window displayed. Select the path where you want to store this file and also specify new file name, you can also use "Key in repository" option which means EncryptPad will store the key in your home directory.
Enter passphrase for the key file on next step, confirm passphrase as well and you should be good to go then.
Now lets perform an encryption operation using the keyfile and passphrase we generate, open any text file in this editor and click the encryption icon as shown encircled in the following screenshot.
The following window will be displayed, under "Parameters" option choose "Encryption", under "Format" option choose from either EPD or GPG (these two are encryption formats supported by this utility) , browse input file and specify the output file, enter passphrase and browse and provide the path to the key file. Click "Start" once done.
Hurrah! Your file has been encrypted now.
In order to decrypt files, you just need to choose "Decrypt" option under parameters. Specify Input, Output file ; browse and provide key file.
Click "Start" and it will ask you for passphrase.
Congratulations, your file has been decrypted now.
That's it, isn't it a pretty easy utility ? :)
