Hi guys I lost my passphrase like an idiot. Good news is I remember part of it for certain. If anyone here can help me I'd love to tip that person, first off my password is either 1 of two things. It's either a set word with numbers and I fat fingered it when I was setting it and am off by a tad, or used an all number password that I forgot the middle of, I for certain know the first 4 digits and last 3 digits but don't remember how long the password is (most likely 12 characters total) If there is anyone here that can help please I would appreciate it greatly.

Doing a similar service for someone else right now. Cracking takes time. You need to do the following:
1) write down everything about the password you know
2) limit the search space by excluding possibilities
3) find someone to run the search (PM me if you can't find another trusted person)

if you know 7 characters for certain, that leaves you with a 5-dim search space. That's about a trillion possibilities, takes about 1 day on a 400-core cluster with 150 trials /sec/core.

I can say this for certain at this point. It's all numbers, no zero's though. I know 7 digits for certain. It's between 11 and 17 characters at most long. I know the first 4 and last 3.

With only 11 characters, if you remember 7 of them, it leaves 6,561 characters to try. Absolutely doable within a few minutes, if not seconds.
If it was 17 characters, and you remember 7 of them, it leaves 3,486,784,401 combinations possible.

Better be 11 characters.
