I have been looking for an encryption/decryption utility for a long time... Of course I found some interesting applications (freeware and commercial) but there was no one that was really good and free/convenient. I also found commercial encrypting software but that one Ive found has caused some problems (very often I had to do a soft-reset in order to turn on my Pocket PC).

With CodeStore you can manage all your passwords on your PocketPC.
The data is encrypted with a single master password.Update

FreeOTFE4PDA is a free, open source, "on-the-fly" (OTFE) transparent disk encryption program.
Using this software, you can create one or more "virtual memory cards" on your PDA - anything written to which will be automatically, and securely, encrypted before being stored.
Features include:
- Source code freely available.
- Easy to use; full wizard included for creating new volumes.
- Powerful: Supports numerous hash/encryption algorithms, and provides a greater level of flexibility than a number of other (including commercial!) OTFE systems.

When you are using a Pocket PC, all your browsing history is stored in hidden files. Even though most people are unaware of that, Internet Explorer (IE) keeps these records and does not delete them when you empty your browser cache or delete temporary files by using third party cleaning software. The location of these files and system behavior greatly depend on the version of Windows on your device. Use this free Index.dat Viewer to analyze the contents of these hidden files at your Pocket PC.
