It is ECDSA, except that there is no hashing algorithm in use. Instead, the hashing algorithm just returns the data that it passes in. This makes it trivial to forge messages with the correct signatures. 1 2 3 4 5 6 7 class HashFunc: def __init__(self, data): self.data = data def digest(self): # return hashlib.sha256(data).digest() return self.data The following is referring to this question on Crypto StackExchange. The answer mentions how the signing of a message is carried out....
