PRL Software's Hash SFX for PalmOS
Sample application
Sample application

Version 2.0 Released May 9, 2001

PRL Software's Hash Encryption extension is a SatForms plugin that provides MD5 and MD4 one way cryptographic hash functions.

This extension is about providing security to applications by utilising the power of Hash. This security is comprised of three main features:

  1. Password Match Verification without needing to store Passwords on the Palm.
  2. Registration Match Verification without needing to store the Registration key on the palm.
  3. Message and Message Origin Verification using "digital signatures".
Although this is not a full-blown security application unto itself, this extension can be used to create one. Extensive details are given of how to set up your own registration program as well as tricks that the Hackers can perform. The MD5 hash functions are utilised as part of Philip Leitch's Registration Security Extension.

All of the informaiton required to set up a secure program is provided with this extension. The documentation explains these concepts in the easiest manner possible so as not to complicate the issue. Example code is given throughout.

There is also a MD5 Hash ActiveX DLL that comes with this extension so as to provide complete PC/Palm security.

This extension is manufactured by PRL Software and is marketed by NOTE: This extension is no longer supported by PRL Software, is not supported by PalmDataPro, and is available on an AS IS basis only.
