sneakText

it uses a custom built alphanumeric text cipher to secure just about any text-related operations you can think of.

Enter a message in the interface, followed by a codeword, select 'sneak' or 'unsneak', and hit 'do it'. The app will then either securely encrypt the message, or decrypt it. Maybe good for those couples who both use WinMo

Tech note: Requires .NET CF 2.0 or later

HideIt!

This program provides encryption facilities for Windows Powered Devices, allowing the user to encrypt/decrypt files from within the device itself.

ideIt! Pro for Windows Powered Devices supports the popular and proven for its efficiency RSA algorithm. An additional algorithm - DES - is also supported, which can be used on top of RSA.
The HideIt! Professional version for Windows Powered Devices is fully compatible with the HideIt! Professional for Windows NT, 2000 and XP


Prerequisites
- Windows Powered device using Windows CE 2.11 or newer.
- 31-580 kB storage memory, depending on the platform and available user options.
- Connection between the handheld and host PC, via Microsoft ActiveSync 3.x.


Installation
- Establish an ActiveSync connection between the handheld and the host PC.
- Execute the installation executable and follow the installation instructions provided.
- When the CE Application Manager window appears, you can either install the program in the default location or on a storage card. The default location corresponds to the internal storage memory of your handheld.


Installation Package
Installation Executable: HideItProCE

Supported platforms:
Palm-size PC (MIPS/SH3, Windows CE 2.11): Casio E-10x, Compaq Aero 15xx, HP Jornada 4xx, Philips Nino 3xx/5xx, Everex, Trogon C2000 Plus.
Pocket PC (MIPS/SH3/StrongARM, Windows CE 3.0 or later): Casio E-115/E-125/EM-500/EG-800/E-200, Compaq Aero 21xx, Compaq iPAQ H31xx/H36xx/H37xx/H38xx, HP Jornada 5xx, Palmax PD-131/PD-600c(@migo).

Bulambod

It is a cipher algorithm created and develop by Mitchelle V. de la Cruz.

It is not base on other cipher algorithm. It was not invented or design today but it was started on 199xs. Yes it is not the same in structure when it was first design but the main goal was to make an unbreakable cipher algorithm. The strength of Bulambod is in the secrecy of password, even programmers, hackers, geniuses or even aliens know the source code it doesn't matter. Bulambod can be design to used infinite password length. You can brute force it but its like your counting stars in the universe or counting grains of sand in all the beaches. You can use even any number systems even number systems that was not invented. Bulambod is a formula, its not difficult as you may think, its simple, its small, it has lots of good usage but beware, and a plea, warning from the author his asking and will condemn anybody who will used this code in any malicious software especially to harm the masses. All rights reserved 19xx to infinite. Anybody has no right to used this algorithm without the approval of the author.

Message encrypter

Suggest usage
--------------------
Information storage: Store your stuff as you already do in your Outlook Note, Contacts, etc securely with encrypted message instead. You may decrypt the information within Blender or some other web pages that use the same algorithm XXTea (i.e. http://www.farfarfar.com/scripts/encrypt/) NOTE: I'm not in any way associate with this site. We are just using the same algorithm. I also have my own Java applet almost ready to be deployed (if anyone is interested) to be hosted on your own webpage, which you will know be always online and secure.

With Blender available in webpages, desktop PC (my Java applet runs as a standalone application too), and Pocket PC, you may actually, encrypt your message and have it written on a piece of paper, to be decrypted anywhere (with or without your Pocket PC)

Message exchange: Send secret message to anyone via SMS. The encrypted message is nearly as long as the original message (approx 25% longer, on block of 4 characters), you can send secret SMS to anyone, with or without a Pocket PC (using webpage decryptor and desktop standand alone application).

Limitation
-----------------
- Does not encrypt message with 4 or less characters
- As with standard XXTea implementation, effective password length of 16 chars
- UNICODE currently not supported

nombCrypt

nombCrypt is an encryption program I originally made for the desktop but then decide to port it over. It uses a password you provide and encrypts either a block of text or files using 256bit Rijndael (AES). This level of encryption was given the ok to encrypt Top Secret documents. It can of course decrypt as well. This is for Windows Mobile 6. Please enjoy and every developer of course likes to get back feedback.
