• Analyze the data from the file "RawTX.json". Script breakECDSA.py reconstructs the unsigned message for each to find the Z value. The result is returned as R, S, Z, PUBKEY for each of the inputs present in the data in the "RawTX.json" file.

• Pollard's kangaroo method computes discrete logarithms in arbitrary cyclic groups. It is applied when the discrete logarithm is known to lie within a certain range, say [ a , b ], and then has the expected time to execute the bulk operation. One way to break ECDSA signature schemes is to solve the discrete logarithm problem.
