How strong is WW2 encryption compared to today's computers?

Bump for interest

>WW2 encryption
You mean stuff like Enigma? All solved, man. Your mobile phone could probably decode the message with the right app.

Pretty much, the bombe could run trough one rotor order in 20 minutes. And they only had mechanical wheels going at 120 rpm

So, impossibility aside, any random guy that happens to time travel back to WW2 times could wreck some serious shit just by decoding army transmissions?

Wait, but what if you didn't know what algorithm they were using? What if you had to start from scratch?

>>57694202
You still need Turing's genius

Cryptography techniques are also quite advanced compared to those years.

Hell the father of modern computing (no offense to von Neumann) was instrumental to figuring that shit out, with the amounts of processing power we have now it'd be way easier.

The NSA can break RSA and AES, repent!!! Jk not rlly.

Enigma is super weak today.

Any random cryptography expert for sure, or any random guy with enough preparation.

Do you know them?

Not really, but "impossible differential cryptanalysis" is my favorite.
