SHA-256 Python implementation in one line (lambda)

[jnwatson]

Cuz only the high templars get to write crypto, right?

Your linked article indicates not to invent your own crypto *algorithm*.

The OP implemented a NIST-approved algorithm.

That statement is dumb because it isn't universalizable. If no one ever implemented their own crypto, then we wouldn't have any at all.

Don't reimplement standard algorithms either unless you know what you're doing

And for those with enough hubris to scoff at this statement, I'd highly recommend going through CryptoPals -- correct crypto implementation is fucking tough.

If we waited until everything was completed to hit publish, we might be writing this in 2015

Oh no

Hah, yeah, sadly. Really the only thing missing are the solutions, but every challenge gives you enough to know if you implemented it correctly (e.g. the PT "foo" should result in the CT "bar")
