Good choice for a lightweight checksum algorithm?

Question

I find myself needing to generate a checksum for a string of data, for consistency purposes. The broad idea is that the client can regenerate the checksum based on the payl

Answer 1

Are aware that both TCP and UDP (and IP, and Ethernet, and...) already provide checksum protection to data in transit?

Unless you're doing something really weird, if you're seeing corruption, something is very wrong. I suggest starting with a memory tester.

Also, you receive strong data integrity protection if you use SSL/TLS.
