WebI'm planning to tackle these over the next few weeks and months (in Python, naturally) but to ensure that I follow through with this turkey-curry-and-port-induced bravado, I was wondering whether others would be interested in joining me. WebGreat answer. I personally would go with Python: it just makes things easier and you can focus on the cryptanalysis concepts. As for how things are implemented, that's a huge separate exercise in itself. Ruby should be fine too, but honestly, investing a little bit of effort in learning python is well worth the effort! fixturing services https://dooley-company.com
