I bought several thousand Bitcoins in 2014. I wrote down the private key on a piece of paper and put it in a drawer. A mouse bit off the last two digits. What should I do if the private key doesn't match?
This is simple. Write a program and fill in the last two digits. There are 58*58=3364 possibilities in total. Then use base58 to decode each possibility into a byte array, because the last 4 bytes are the total of all the previous bytes. The first 4 bytes of the result of sha256 twice, so you can write a program to traverse all possibilities.
If there are multiple possibilities that meet the conditions, then use the obtained private key to calculate the address, call the API interface of the block explorer to query the balance on each address, and finally determine the correct private key you saved at that time. These tasks are really too easy for computers.
If you have lost part of your private key, you can try it. Have you learned it?
