SSLScan Tool

SSLScan is a command-line tool used to test SSL/TLS configurations of a server. It helps security professionals and system administrators analyze the security of SSL/TLS implementations, checking for supported cipher suites, protocol versions, and other security-related details.

Tool Features

Some of the tool features are as follows:

• Identifies supported SSL/TLS protocols
• Lists supported cipher suites
• Checks for weak or vulnerable ciphers
• Displays SSL certificate details
• Useful for penetration testing and security audits

Install SSLScan

SSLScan comes pre-installed in Kali Linux. If you need to install it manually, use the following command:

$ sudo apt-get install sslscan

Basic Usage

To scan a website for SSL/TLS details, use the following command:

$ sslscan example.com

This command tests the SSL/TLS configuration of the given domain and displays details about supported protocols and ciphers.

Checking for Weak Ciphers

To check if a server supports weak ciphers, run:

$ sslscan --no-failed example.com

This command filters out failed tests and highlights weak configurations.

Scanning a Specific Port

By default, SSLScan scans port 443. To specify a different port, use:

$ sslscan example.com:8443

This is useful when scanning non-standard HTTPS ports.

Saving Results to a File

To save the scan output for later analysis, use:

$ sslscan example.com > results.txt

This redirects the output to a file named results.txt.

SSLScan is a powerful and easy-to-use tool for analyzing SSL/TLS security. It helps identify weak configurations and ensures a secure server setup. Regularly scanning web servers with SSLScan can help prevent security vulnerabilities.
