/**

 * <p>This is a low level API and when using the regular {@link Wallet} class you don't have to call this yourself.
 * When working with more complex transaction types and contracts, it can be necessary. When signing a P2SH output
 * the redeemScript should be the script encoded into the scriptSig field, for normal transactions, it's the
 * scriptPubKey of the output you're signing for.</p>
 *
 * @param inputIndex   input the signature is being calculated for. Tx signatures are always relative to an input.
 * @param redeemScript the bytes that should be in the given input during signing.
