The only problem with this is, assuming the OP's password is reasonably strong, it'll probably take a couple of million years to crack the password using a dictionary attack on an average PC, and I'm assuming the OP wants access to the wallet before the sun burns out.

True, but if you know what your password was supposed to be then it is trivial to make a dictionary that covers any transposed or double keys or missed characters. I have in the past made the same typo on a password and the confirmation window. It took me hours trying different typos to get it.

If you set up a dictionary based cracker you could feed every password you have ever used into a password fuzzer.

Your encrypted data is available in your page source.

This means you can copy it to your computer and run a dictionary attack on it offline.

This will allow unlimited guesses at a fast rate. I do not know of any software already made to do this, nor have I checked what method they use for encryption but I imagine it is just AES-256.

I could write it for the right bounty.

Did you set any password hints? Try writing the password in plaintext exactly how you think it should appear and copying and pasting it.

Are you sure the identifier is correct? When was the last time you logged in and did you change the password recently? If you open a ticket at https://blockchain.zendesk.com/ I can send you the last 50 wallet backups but it won't do any good if the password is indeed incorrect.

can you give me the wallet backups?

You are by yourself now, try to remember your password, even piuk can't help you.

The most likely reason is that you are mistaken about what the password is. This can happen for a few reasons such as:

Caps lock (or num lock) was on when you created your password
Caps lock (or num lock) are on when you are now trying to access the account
You made a typing error when creating your password and didn't realize it
You are repeatedly making a typing error now
You are mistaken about the chosen password, and it is actually a completely different password

Of course, although it is unlikely, it certainly is possible that the encrypted data is somehow damaged and therefore your password will no longer work.
