If you can remember, developer maxthebest has released the Cypher-Me IRShell plugin a few months back. The homebrew application lets you encrypt or decrypt any file you have highlighted in your IR Shell's file browser. Today, the homebrew dev maxthebest has upgraded Cypher-ME IRShell plugin version 0.2 again.

Encryption for the uninitiated is a process where you make files unreadable for other people, except for those with the key. Decryption reverses this. Now, what are the new changes for Cypher-Me IRShell plugin version 0.2 (05/11/008)? Well, you can now encrypt or decrypt any file directly.

If you do this procedure before, you would have to create a new file. With Cypher-Me IRShell plugin version 0.2, you can also know whether a file is encrypted or not. That is just one of the many features for the new build. We have the complete changelog for version 0.2 (05/11/08):

• You can now encrypt/decrypt the file directly, so it does not create a new file.
• Now, if there is not enough room on the memory stick, it will display a message telling you you can't encrypt the file (it used to crash if file was too big)
• Now it displays "encrypting" when encrypting, and "decrypting" when decrypting, it used to display encrypting, even when you were decrypting.
• Added a way to know if file is encrypted or not (see above)
• Added a menu

Note that you need the latest version of dev Ahman's IRshell to make Cypher-Me version 0.2 work. Not to worry, you can download IRshell here. With that settled, here is a guide on how to install Cypher-Me version 0.2 from dev maxthebest. Take note of the installation instructions:

1. Put the Eboot.PBP to IRSHELL/EXTAPP/APP19/
2. Configure the plugin through the irshell configurator, put Encrypt as name and 19 for the address.
3. Now when you want to encrypt a file just press start highlighting it and press the Encrypt button!
