I have a p2sh address generated with an uncompressed public key (from my ledger) and a compressed public key (a bitcoincore wallet). Both signatures are required to send money. When I use my nano ledger to sign, I get the output:
I’m using Ledgerjs library to get this and use the signP2SHTransaction function. I usually insert my private key into the bitcoin core
signrawtransaction Post but I’m sure this is scriptSig. I just don’t know of any libraries that allow me to use this to sign rawtx. (I looked at python-bitcoinlib but couldn’t find a way to get the rawtx info into a readable format.)
Any suggestions on a tool I can use to take this to sign raw tx hex for transmission on the wire?
