Hi,

I wrote my private key on the paper, and i tried to retrieve the btc from the address recently, but found my private key only contain 50 characters! It is my mistake when record down the private key!!

The private key format is WIF without any compressed, base58, start with "5".
I've 50 characters on hand, is there any brute force tools to calculate the key in quick way?

Thank you.

If you're sure that you are only missing 1 character, and that you got ALL the other characters correct, then you have less than 3,000 possibilities to try. A computer program could probably try all the possibilities in less than a second.

Do not give your private key to anybody else to try for you (unless you are VERY CERTAIN that they are trustworthy). And be VERY careful about any programs anybody else gives you (since they could be trying to trick you into running wallet stealing software).

Pretty easy to hack something together in bash or perl, just loop trough all the characters, add them to the end of your private key, and try to import them using JSON-RPC, either into bitcoin core or to blockchain.info
