PWDTK.NET
DESCRIPTION
This API uses the PBKDF2 specification with HMACSHA512 as the underlying pseudo random function (PRF) to perform the salted hashing over a specified number of instances to eliminate the feasibility of rainbow table attacks & drive up the computing cost of generating said tables, this is known as key stretching.This API also provides the capability to create BIG crypto random salt strings, because the BIGGER & more RANDOM your salt, the better! (anti-rainbow tables)
I was going to use Microsofts Rfc2898DeriveBytes(cb) implementation but after learning that it is using HMACSHA1 as the underlying PRF, I decided to modernise this & implement PBKDF2 with HMACSHA512 instead (Stronger against GPUs)

Features
- Crypto Randomly Generate Salt
- Password Policy Integration
- PBKDF2 implementation using HMACSHA512 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
