I am currently trying to crack a Traditional DES [128/128 BS SSE2] enryption using John the Ripper with c/s: 3379K.

I wanted to know the maximum time in which the encryption can be cracked.

Are you talking about DES encryption, or the DES bases crypt hashing scheme? – CodesInChaos Jul 15 '12 at 18:00

By my calculations, you have a 50% chance of cracking the key in 8,100 years. – David Schwartz Jul 15 '12 at 23:58

Is there a reason you're not using oclHashcat? It supports cracking DES crypt on a GPU, which will be much faster than a CPU-only approach. The benchmarks they provide suggest that a modern graphics card should give you at least ~10x your current rate, and a dedicated cracking machine (multiple GPUs) could reach 500,000 c/s. Still, it's gonna be 168 years before you hit the 50% confidence mark. – Polynomial Jul 16 '12 at 8:01
@Cracker: Something entirely different from what you're doing. Like either forget trying to crack things with real security or investing in the hardware needed to do something like that. – David Schwartz Jul 16 '12 at 9:27
