sign_message keeps giving same signature,, for the same private key and message

Describe the bug When I try signing the same message with the same private key multiple times, the function keeps returning the same signature. But according to standard EDSA algorithms, the signatures would be different every time. Am I doing something wrong?

To Reproduce Steps to reproduce the behavior: import pybtc

pk = "Kz36wrYMg9cnKmpV6aucemPa1EAoxwKRo5DBsBML7dLbXbgcsE6K"

public = pybtc.private_to_public_key(pk) print("public = " + public)

a = pybtc.sign_message("6865790D0A", pk, hex=True) print(a) b = pybtc.verify_signature(a, public, "6865790D0A") print(b)
