Hello, Mangos Community! I'm trying to developing python core from scratch and using your project as example. Currently my client stucks on 'Connected' and I think problem can be with packet encryption. Can anybody help me with debug or advice ? This is my project. And this is how packet encrypted: class HeaderCrypt(object): ENCRYPT_HEADER_SIZE = 4 DECRYPT_HEADER_SIZE = 6 def __init__(self, session_key): self.session_key = session_key self.send_i = 0 self.send_j = 0 self.recv_i = 0 self.recv_j = 0 def encrypt(self, data): assert len(data) >= HeaderCrypt.ENCRYPT_HEADER_SIZE encrypted_header = [0] * HeaderCrypt.ENCRYPT_HEADER_SIZE for index in range(HeaderCrypt.ENCRYPT_HEADER_SIZE): enc = (data[index] ^ self.session_key[self.send_i]) + self.send_j enc %= 0x100 encrypted_header[index] = self.send_j = enc self.send_i = (self.send_i + 1) % len(self.session_key) return bytes(encrypted_header) + data[HeaderCrypt.ENCRYPT_HEADER_SIZE:] def decrypt(self, data): assert len(data) >= HeaderCrypt.DECRYPT_HEADER_SIZE decrypted_header = [0] * HeaderCrypt.DECRYPT_HEADER_SIZE for index in range(self.DECRYPT_HEADER_SIZE): dec = (data[index] - self.recv_j) ^ self.session_key[self.recv_i] dec %= 0x100 decrypted_header[index] = dec self.recv_j = data[index] self.recv_i = (self.recv_i + 1) % len(self.session_key) return bytes(decrypted_header) + data[HeaderCrypt.DECRYPT_HEADER_SIZE:]
