How exactly would you decrypt a 3DES ciphertext "with little effort"?
- 1970-01-01 10mo agoIt's supported in hashcat
- some_furry 10mo agoIs this a bit?
- 1970-01-01 10mo agoHave you tried it?
- some_furry 10mo agoWe're talking about symmetric ciphers and you're talking about password cracking software. Triple-DES has 168 bit keys. Even if you use a meet-in-the-middle attack, your attack cost has an exponent of 112 (with an associated memory cost with an exponent of 88). That's not practically exploitable today. If you think I'm wrong, here's a single block message encrypted with 3DES, then hex-encoded. Have fun: 924db449f52ea976 But really, the bigger problem is Sweet32.
