Resued R-Value : a0897f1b7a7f0db9acb517ae2b6d53dda3833808d02c6a1cc21dc1a68680

How do I find the s and z of the reused r value?

user43221: The one of the best way (I do it by that way) to find reused R values is to parse the raw blockchain database with my blockchain parser with extracting only Input script and TX hash values and then cut off from script strings all except R value. So you get all R values ever generated. Then you can check those data for reusing R and easily find those TX's full data using it's hash.
This is the universal automated method for making such research for blockchain. I think this way is not the way like getreusedr > result.txt but I think it also can help you very much.
