Ethereum SSL Certification Validation Failed with Binance Connector for Python

As a developer building an application to detect pumps and dumps in the crypto market, I decided to utilize Binance as my primary platform. To facilitate secure communication between my app and the Binance API, I installed the Binance-Connector library using pip3 install binance-connector on my macOS machine.

Installing Binance Connector

The installation was straightforward: pip3 install binance-connector. The package is well-maintained and easy to use. However, after installing it, I encountered an unexpected issue that would prevent my app from connecting to the Binance API using the connector.

SSL Certification Validation Failed

Upon attempting to connect to the Binance API, I noticed that SSL certification validation failed for the binance-connector. This error usually occurs when the library is unable to establish a secure connection to the Binance server due to certificate issues. Let’s dive into the details and explore possible solutions.

What’s an SSL Certificate?

In cryptography, an SSL (Secure Sockets Layer) or TLS (Transport Layer Security) certificate is a digital certificate that verifies the identity of a web application or server. It ensures secure communication between the client and server by encrypting data in transit. A valid SSL/TLS certificate is essential for establishing trust with the Binance API.

Why Did My Certificate Fail?

There could be several reasons why your SSL certification validation failed:

• Incorrect or Missing Certificates: Ensure that both your local machine and the Binance server have the correct SSL certificates installed.

• Certificate Expired: Check if the certificates are expired or have been revoked. You can renew them using tools like Let’s Encrypt or manually update them in your configuration files.

• Server-Side Certificate Issues: The issue might be specific to the Binance server’s certificate settings or configuration.

Solution: Update Certificates and Re-Install Connector

To resolve this issue, I will update my certificates and re-install the binance-connector library:

• Update Certificates: I replaced my old SSL certificates with new ones using Let’s Encrypt. This ensures that both my local machine and Binance server have the latest and most secure SSL/TLS certificates.

• Re-Install Connector

  : After updating my certificates, I re-installed the binance-connector library: pip3 install binance-connector. Make sure to update your settings.py file with the new SSL certificate path.

Updated Code

import os

from dotenv import load_dotenv

from pathlib import Path


load_dotenv(Path(__file__).parent / ".env")







Update SSL certificates

os.environ['Binance_API_KEY'] = 'YOUR_BINANCE_API_KEY' 
Replace with your actual API key

os.environ['Binance_API_SECRET'] = 'YOUR_BINANCE_API_SECRET' 
Replace with your actual API secret

os.environ['Binance_API_URL'] = f'



Re-Install connector and update certificates in settings.py

from binance import Client


client = Client(binance_config='settings')

Conclusion

By following these steps, you should be able to resolve the SSL certification validation failed issue with the Binance Connector for Python. Ensure that your local machine and Binance server have the correct SSL certificates installed, update them if necessary, and re-install the binance-connector library.

If you encounter any further issues or need assistance with troubleshooting, feel free to ask. Happy coding!
