Similar to my project PWDTK.NET (http://sourceforge.net/projects/pwdtknet/), I have decided to port this over to the mobile environment for use in the Windows Phone OS.

This is essentially the same as PWDTK.NET however it is using HMACSHA256 as the underlying PRF of the PBKDF2 spec as opposed to HMACSHA512. This is due to Microsoft not including HMACSHA512 in the Windows Phone SDK.

Usage is essentially the same as with PWDTK.NET so you may also like to look at the PWDTK.NET project for more documentation etc.

I will put binaries here, but please get source code from my GitHub repo: https://github.com/Thashiznets/PWDTK.NET-Mobile.git

Features

  • Windows Phone Implementation of PWDTK.NET
  • Crypto Randomly Generate Salt
  • Password Policy Integration
  • PBKDF2 implementation using HMACSHA256 as the underlying PRF
  • Control resource usage vs key stretching by supplying iteration count as per PBKDF2 spec
  • Code open source and available for peer review by security experts\cryptographers
  • Uses UTF-8 encoding to support non English characters, better than implementations using ASCII
  • Created using instructions for PBKDF2 standard here: http://www.ietf.org/rfc/rfc2898.txt
  • Ability to call Rfc2898.PBKDF2(P,S,c,dkLen) to derive encryption keys of your specific size
  • Source code includes sample GUI with common usage implemented
