Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it
Here is the script.
Nice script i really like it, i may learn something from you
Here there is a function that I use for my keyhunt bsgsd server:
Code:
def send_and_receive_line(host, port, message):
# Create a TCP socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
# Connect to the server
sock.connect((host, port))
# Send the message
start_time = time.time()
sock.sendall(message.encode())
# Receive the reply
reply = sock.recv(1024).decode()
end_time = time.time()
# Calculate the elapsed time
elapsed_time = end_time - start_time
sock.close()
return reply, elapsed_time
except ConnectionResetError:
print("Server closed the connection without replying.")
return None, None
except ConnectionRefusedError:
print("Connection refused. Make sure the server is running and the host/port are correct.")
return None, None
except AttributeError:
return None, None
# Create a TCP socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
# Connect to the server
sock.connect((host, port))
# Send the message
start_time = time.time()
sock.sendall(message.encode())
# Receive the reply
reply = sock.recv(1024).decode()
end_time = time.time()
# Calculate the elapsed time
elapsed_time = end_time - start_time
sock.close()
return reply, elapsed_time
except ConnectionResetError:
print("Server closed the connection without replying.")
return None, None
except ConnectionRefusedError:
print("Connection refused. Make sure the server is running and the host/port are correct.")
return None, None
except AttributeError:
return None, None
This function only send a message to a IP:port and wait for the reply returning it also the time elapsed (For speed calculation)
I call the previous function with this one that format the publickey with range_A:range_B
Code:
def keyhunt_client(target):
host = 'localhost' # Change this to the server's hostname or IP address
port = 8080 # Change this to the server's port number
message = "{} {}:{}".format(target["publickey"],target["start"],target["end"])
reply, elapsed_time = send_and_receive_line(host, port, message)
if( reply != "404 Not Found"):
return reply
else:
return None
host = 'localhost' # Change this to the server's hostname or IP address
port = 8080 # Change this to the server's port number
message = "{} {}:{}".format(target["publickey"],target["start"],target["end"])
reply, elapsed_time = send_and_receive_line(host, port, message)
if( reply != "404 Not Found"):
return reply
else:
return None
I use some target because i have a list of all puzzles with their respective ranks
With those codes you don't depend of Netcat or shell commands.
Here's my option.
Code:
def send_request(self, pub_key, range):
global key_found
request_str = f"{pub_key} {range}"
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
s.connect((self.server_address, 8181))
s.sendall(request_str.encode())
response = s.recv(1024)
response_str = response.decode().strip()
if response_str not in ("404 Not Found", "400 Bad Request"):
print(f"\nThe private key for {pub_key} is: {response_str}")
with open('Found.txt', 'a') as f:
f.write(f"Public key: {pub_key}, Private key: {response_str}\n")
key_found = True
except ConnectionRefusedError:
print(f"Connection refused by {self.server_address}")
self.connected = False
finally:
s.close()
def check_server(self):
self.connected = check_server(self.server_address)
def check_server(server_address):
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.settimeout(5)
try:
s.connect((server_address, 8181))
return True
except socket.error:
return False
finally:
s.close()
global key_found
request_str = f"{pub_key} {range}"
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
s.connect((self.server_address, 8181))
s.sendall(request_str.encode())
response = s.recv(1024)
response_str = response.decode().strip()
if response_str not in ("404 Not Found", "400 Bad Request"):
print(f"\nThe private key for {pub_key} is: {response_str}")
with open('Found.txt', 'a') as f:
f.write(f"Public key: {pub_key}, Private key: {response_str}\n")
key_found = True
except ConnectionRefusedError:
print(f"Connection refused by {self.server_address}")
self.connected = False
finally:
s.close()
def check_server(self):
self.connected = check_server(self.server_address)
def check_server(server_address):
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.settimeout(5)
try:
s.connect((server_address, 8181))
return True
except socket.error:
return False
finally:
s.close()
