Since the "Checksum Calculators" area lacks a program that can handle unicode, this should be a good addition. It calculates MD5, SHA1, and CRC32.

A lot has changed about this program since the last time I tested it including more SHA hashes and VirusTotal submission, bringing it line with other similar programs here on the site. I like it. Program entry and screenshot have been updated.

Wouldn't it be time to implement Blake2b? It's faster e more secure:

While I agree on principle, let it be noted that the same applies to most hashers posted at TPFC.

Yes, you're right.

I'm impressed that it's faster than MD5, but I wonder how it performs with something other than modern processors. As BLAKE was written specifically for those toolsets, older machines (especially 32-bit), cell phones, and anything with an ARM processor will likely not have that kind of speed.

Regardless, if I was going to run de-duplication on a large file collection, it seems like Blake would be the way to go. Also, if services like Virustotal start using it for file reputation, I think it would take off rapidly. However, for my own local file verification, I'll probably stick with CRC32 checks.

SHA1 Cracked?
SHA-1 has been subject to more attacks since then: https://en.wikipedia.org/wiki/SHA-1#The_SHAppening
Wikipedia wrote: The authors estimated that the cost of renting enough of EC2 CPU/GPU time to generate a full collision for SHA-1 at the time of publication was between US$75K–120K, and noted that was well within the budget of criminal organizations, not to mention national intelligence agencies. As such, the authors recommended that SHA-1 be deprecated as quickly as possible.
Of cource, no one is going to spend a hundred grand to compromise a random freeware program, so how much these attacks matter depend on what exactly SHA-1 is used for.
