I'm looking for a light, fast hash/checksum calculator (eg. MD5, SHA1, etc.). I've been using HashCalc and it works fine enough, but I was wondering if there was something better.
When downloading .ISOs from MS BizSpark, I've found that it's essential to check the SHA1, and I'm sure that other people have found the same. So what's the defacto, light, fast, simple app that does the job?
