I have an old paper wallet with Private Keys of 58 characters (all starting with a 6). These can be imported e.g. on blockchain.com, but since I still have BSV on this key, I have to import/sweep it in ElectronCash or ElectrumSV, which doesn't take this format.
So, does anyone know, how to convert this key into WIF (without coding if possible)? Thanks in advance!
