PRL Software's DES Encryption extension is a SatForms plugin that provides Triple DES encryption and hexadecimal data conversion functions.

The DES Encryption extension provides full encryption for Satellite Forms developers on the Palm Pilot. The encryption provided is the "Triple Data Encryption Standard" or 3DES. It is also known as "Data Encryption Algorithm" or DEA.

Up until now there has been no real method of safe guarding data on a palm. Tables can easily be retrieved from the palm or "beamed" to a PC or other device. If the data is encrypted then any malicious or devious person attempting to read or change data will be effectively blocked. This is invaluable for customer lists/details or personal/private memos.

This extension lets you encrypt and decrypt and ASCII (text) data within Satellite Forms, including:

• Variables
• Text enclosed in quotation marks, e.g. "Text to be Encrypted/Decrypted"
• Database Fields
• Control data, e.g. EditboxCustomer_Name.Data

The results can also be placed into a variable, database field or control. This means that data can be stored in a database in an encrypted format, to be decrypted on the PC. An ActiveX DLL - PalmDES.DLL - is provided with the same methods as the extension, meaning that code can be transferable between Palm and PC for encryption/decryption tasks.

Included with this extension is the ability to store and send any standard ASCII character from the PC to the Palm and from the Palm to the PC. This resolves the international character problem of various Satellite Forms versions that inhibits the Palm sending the PC extended ASCII codes.
