Have a go, Theres actually only 1.1 BTC in the wallet, Im positive the first word of the password is 'Hello' with a capital H , the last charachter is a 1, everything in between I havent a clue, one or two words I reckon. If anyone gets it I'd love to know what the password was and if your feeling exceptionally generous you could give me some of my money...  Anyway enjoy , ask any questions you want re: password

The number of characters between the "Hello" and the "1"?  Are you certain that there is more than one character?  Can you say with certainty that there are more than 3?  How about 5?

Same question on the high side.  Definitely less than 100 characters?  Less than 25 characters? Less than 10?

Specifically what I'm asking is what is the smallest range of quantity of characters that you can say there are with certainty between the "Hello" and the "1"? (Positively more than 1, and less than 100, but can we narrow it down a bit more than that?)

Question 2.

Can you say with any certainty what type of characters definitely exist between the "Hello" and the "1"?

Upper case?
Lower case?
Numeric?
Symbols?
Spaces?

Can you say with any certainty what types of characters definitely do NOT exist between the "Hello" and the "1"?

Upper case?
Lower case?
Numeric?
Symbols?
Spaces?

Do you have a set of words that you think you'd be likely to use?

Is there any type of word you are likely to use or to avoid?

Peoples names?
Animals?
Technical concepts?
Hobbies?
Colors?
Verbs?
Objects?
Adjectives?
Vulgar words?
Stuff from your every day life?
Medical words?
Something Cherished?
Etc.

1. I reckon its between 4 and 8, again I cant remember if im remembering failed password attempts or the original, I can guarantee its less than 15 though , i would never use a password that long,

2. Everything is lower case after the first capital, there may be a slight chance there is a #  before the 1 but I doubt it

3. Regards to words: chronic, number , everyone, everybody, one (I was really high when I did this so its something stupid and easy I think)
I reckon if you were going to try you would be better off using a dictionary attack if these words dont help you

I'll take a stab at it. Can't make any promises.
I'll let you know.

if you are unable to brute force it now consider that you may be able to at some point in the future. write down everything you can remember somewhere safe and save the encrypted wallet somewhere safe. Then someday if your 2 bitcoins are worth 200,000 dollars you can rent some serious computer power in an attempt to crack it.

If one can not confer upon another a right which he does not himself first possess, by what means does the state derive the right to engage in behaviors from which the public is prohibited?

Error: wallet.dat corrupt, salvage failed

Are you sure you sent us the right file? I'm not sure what's up with it.

Definitely, I was just trying to reduce the number of words in the "dictionary" that would need to be used.  Also, if you were "really high", then there's a pretty good chance that you misspelled the words you used.
