How to quickly find the private key from Segwit P2SH address?
How to quickly find the private key from Segwit P2SH address? I have a very large list of Segwit addresses for bitcoin, starting with '3' and do not know the corresponding legacy '1' address for them. How can I quickly find the corresponding legacy address to export the private key from Bitcoin Core? The Seqwit addresses have not received any transactions, yet. I think I will need a script, or a program maybe... [this is an issue with LTC having been sent to a segwit address generated using Bitcoin Core] http://ift.tt/2BL7HpL
