SSHole

SSHole is a highly functional, open-source software designed for debugging SSL-encrypted protocols. It’s a small command-line utility that serves as a proxy for SSL connections, copying all the traffic to your local standard output.

Whether you need to test your SSL implementations, verify SSL connections, or monitor the traffic between clients and servers, SSHole is your go-to solution. When you run the program, it listens for client connections on a specified port, and as soon as a connection is received, it connects to the remote host and operates as a transparent proxy.

With SSHole, you don't have to worry about any complicated configurations or settings. Simply launch the program and let it serve as many connections as you need. This makes it an easy-to-use and highly efficient solution, especially for developers who need to debug multiple secure connections in one go.

Moreover, SSHole is built using popular SSL libraries such as OpenSSL, SSLeay or GnuTLS, giving you the flexibility to choose the one that best suits your needs. Overall, SSHole is an excellent, free utility that can help secure your connections, debug your SSL implementations, and monitor your traffic seamlessly.
