I know there's set of Bitcoin cryptography tool https://github.com/demining/CryptoDeepTools, but i never try it myself.

His soft work only with his DEMO SIGHNATURES ONLY !!!! WE ARE BUY HIS SOFT AND KNOW WHAT TALK ABOUT !!!!

I don't know about other part of the script, but i can run script to get R,S,Z from arbitrary raw transaction hex. Here are the steps to run the script,

Code:

$ git clone https://github.com/demining/CryptoDeepTools
$ cd CryptoDeepTools/02BreakECDSAcryptography/
$ python2 -m pip install -r requirements.txt
$ python2 cat breakECDSA.py [RAW TX HEX]

Example on raw TX, where all input is P2PKH[1].

Code:

$ python2 breakECDSA.py 0100000001f65499107b1714a70409c528d4ca2214516dd62005ddac99848cf55350fe75f1000000006b483045022100c27f019f3112e3dbf4f067e057d6b20e9a5bb847f47e65ba7769bf62eb5192a5022070c77e2c0b3570594e5aec0166b3a08b958d0aedde8d07e917ee9831641a3cc801210369e03e2c91f0badec46c9c903d9e9edae67c167b9ef9b550356ee791c9a40896ffffffff0249e36002000000001976a9149f21a07a0c7c3cf65a51f586051395762267cdaf88ace0aa1500000000001976a91421937d90affbc4161261cfc5e70380d79c39434988ac00000000

But this script doesn't work on P2WPKH[2] or P2WPKH-in-P2SH[3] input, so it's not useful for OP use case though.
