Mahlzeit!
Normal nehme ich Truecrypt (alte Gewohnheit durch die frühere Benutzung von E4M), aber für PDAs mit Windows CE bleibt nur Freeotfe4PDA welches aber sehr gut ist (kenne nur die PC Version welche praktisch identisch ist).

FreeOTFE v2.00 and FreeOTFE4PDA v2.00
FreeOTFE: A free "on-the-fly" transparent disk encryption program for PCs
(MS Windows 2000/XP/Vista) and PDAs (Windows Mobile 2003/2005)
Using this software, you can create one or more "virtual disks" on your computer - anything written to these disks is automatically, and securely, encrypted before being stored on your computers hard drive.
History:
PC Version
* v2.00.00 (18th March 2007)
* Implemented support for Windows Vista (although previous versions would work under Vista, they had a few minor issues)
* Added option to allow mounted volumes to be visible to all logged on users, or just the current user
* Added option to associate ".vol" files with FreeOTFE, in line with the PDA version, and defaulted open/save dialog filters. (Note that you are still free to use any filename with any filename extension).
* Added ability to store FreeOTFE settings in different places, or not at all if required
* Updated to automatically prompt user if they want to start portable mode if the main FreeOTFE driver isn't installed/running
* Added indicator to show portable mode activating
* Added ability to combine random number generators (RNGs) when generating random data for new volumes/changing passwords
* Added option to start FreeOTFE in portable mode without prompting if no installed drivers are found
* Added option to suppress prompting for volume type when volume files are drag 'n' dropped onto FreeOTFE
* Added additional prompt when creating new volumes to make it clearer when the minimum amount of information required had been entered
* Added option to allow user to specify where their settings should be stored (if they are to be saved)
* Added extra support for "odd" LUKS volumes which don't use the same cypher keylength for IV generation as encrypting data (e.g. volumes which use Blowfish-448 for data encryption, and cbc-essiv:sha256 actually use Blowfish-256 for their ESSIV IVs - this is now supported)
* Added detection of (nonstandard) Tiger and Whirlpool hashes when using LUKS volumes
* Removed redundant warning about drivers not being started in portable mode when they had been manually installed
* Corrected minor cosmetic issue with status bar display
* Added OS version ID to human readable CDB dumps
* Moved weaker drivers (FreeOTFE4PDAHashNull.dll, FreeOTFE4PDACypherNull.dll and FreeOTFE4PDACypherXOR.dll) into a "weak drivers" directory; most users shouldn't use these drivers, but they're still included in the release if needed
