Any particular algorithms you think would be useful here?

selurvedu commented 10 months ago

Definitely CRC32 for me. Here are some other popular options:

Generally I'm more interested in algorithms that produce shorter checksums (e.g. Adler-32 and other CRCs) as I see them being used more often in things I'm reverse engineering.

Merged to master.
