IKE Preshared Key from Aggressive Mode VPNs
1. Any thought to implementing "ikescan/psk-crack" functionality in hashcat?

2. Anyone know of a better solution to recovering PSKs than using psk-crack? I'm looking for a GPU or clustered solution.

Rainbow table use is not possible due to HMAC hashing of SHA1/MD5 value as I under it....

As a professional pentester of 10 years a GPU based cracking implementation for PSK aggressive mode seems like an obvious thing to do. I assume that I'm not aware of a GPU solution already implemented? Hope so anyway. We see over 90% of our clients allowing aggressive mode and I'm tried of saying it's 'possible' to break that key; I'd rather show them.

Thanks in advance.
