Have you tried to generate a SHA256 checksum for a file in the browser, no matter what crypto lib or api is available to you ?
Have you tried to generate it using Python standard lib ?
I did, and doing it in the browser was so bad that it was unusable. I suspect that it's not the crypto that's slow but the file reading. But anyway...
> SHA256 in pure Python would be unusably slow
None would do that because:
> Python's SHA256 is written in C
Hence why comparing "pure python" to "pure javascript" is mostly irrelevant for most day to day tasks, like most benchmarks.
> Javascript is fast. Browsers are fast.
Well, no they were not for my use case. Browsers are really slow at generating file checksums.
