Ripe MD Implementation in Powershell.

RIPMEMD160 hashing in Powershell.

• [WIKI - http://en.wikipedia.org/wiki/RIPEMD]
• [MSDN - http://msdn.microsoft.com/en-us/library/system.security.cryptography.ripemd160(v=vs.110).aspx]

RipeMD supports avalanche effect, whereas a small change in the original input results in a significant change in the hash. Also a zero-length string has a hash. (But it was difficult for me to implement a zero-bytes input, around the Get-Bytes class.)

• [Avalance Effect - http://en.wikipedia.org/wiki/Avalanche_effect]

The MSDN page suggests that RIPEMD160 class is supported in .Net 2.0 Framework. This gives me a nice little hashing mechanism which is not MD5. (This is a feature request)

Here is an interesting discussion on which hashing algorithim should you choose. http://stackoverflow.com/questions/800685/which-cryptographic-hash-function-should-i-choose

Here is the code.
