- detaro 7y agoBut the OP clearly didn't ask about doing it as a challenge or to understand how it works (which is what cryptopals is about), but actual usage.

But the parent of the comment I was replying to clearly had the former in mind, as a subsequent comment showed.[0] [0] https://news.ycombinator.com/item?id=21240429 https://news.ycombinator.com/item?id=21240429
- dahart 7y agoTo be fair, the main thing you learn doing the cryptopals challenge is to not write your own crypto. I had a lesson in writing crypto once, when I made what I thought was a good enough secret mixing procedure to encode some data I wanted to email outside of a company that didn’t allow web access. (Long time ago, circa 2000). It all looked undecipherable and I sent most of the data before I discovered that strings of binary zero were leaking my secret key. Oops, pretty stupid.
