Is it possible to recover the last few lost digits (10) of my Litecoin wallet private key? Are there any recovery tools available? Or will I have to try and roll my own? Crucially, what crypto function will I be working against?
I understand that a upper/lower alphanumeric 10char keyspace is effectively uncrackable, but this key was in wallet import format, which I understand incorporates some redundancy/error detection à la MOD10 credit card number verification. I'm wondering if 10 characters of lost private key is therefore recoverable in a reasonable time frame.
Back story: When I hurriedly 'saved' my liteaddress.org keypair as a PDF using Chrome, 10 chars of the private key were clipped. It actually appeared to be 15 or so missing characters that were clipped, but a PDF recovery tool revealed some of the hidden characters. I did not notice this at the time, and paid into the wallet.
My lost wallet contains the proceeds of most of my mining to date. It's not a huge amount of money, but it would be a shame to waste it.
I'm aware that this all sounds extremely dodgy. As a testament to the fact I am seeking to recover my own key and not someone else's, I am happy to use my real name / main Stack Exchange profile to ask this question.
