Hi, I'm trying to use my wallet private key in my application. I got a Base58 string as the response of the dumpprivkey command which should be in the Wallet Import Format specified by bitcoin documentation. However the length of the dumped private key is wrong (41 bytes instead of the valid 32 or 33 depending of the compression) and also if I try to make a checksum validation it fails (verifying the last 4 checksum bytes against the double hash of the private key bytes without the last 4 bytes of checksum).
Can you please explain the dumped private key format you use in multichain? Thanks a lot
