But take note this script doesn't support Witness data, so you can't use it to get R/S/Z value from Bech32 address and SegWit wrapped on P2SH address.
Mine is a P2SH address. yes i have this program. it doesnt work on my P2SH address. is there any other website or script u can recommend specifically for P2SH addresses?
I'm not aware of tool which can parse signature and get R,S,Z automatically from P2SH address. After P2SH address could do LOTS of things such as P2WPKH-in-P2SH, P2WSH-in-P2SH, multi signature or even custom puzzle challenge. I know there's set of Bitcoin cryptography tool
https://github.com/demining/CryptoDeepTools, but i never try it myself.
