in reply to Encryption/hashing algorithm.

This looks to me like a CRC algorithm.

If it is (and I haven't analysed it extensively) it is not very well implemented.

Crypto-wise the algorithm is linear and hence trivially insecure. It may be a reasonable hashing algorithm for a certain class of problem, but it certainly isn't a good encryption algorithm.

Here is a guide to CRCs "everything you ever wanted to know but were afraid to ask..."

And here is my favourite reference for crypto design
