If I have an unsigned Raw Transaction whose inputs are from a multisignature wallet, can I sign the transaction with only of the N needed keys and having the output as raw transaction again using BitcoinJ and/or Java native cryptography libraries?
The case I want is the same as this page of Coinb.in: https://coinb.in/#sign So I have as input a raw transaction and a private key, and also the multisignature redeem script if needed, and i want in output the raw transaction with the signs that were before (if there were signs) + the sign from the private key i provided as input.
