Check your SSL/TLS connection security. Verify TLS version, HTTP protocol, cipher suite, and security rating. Free SSL certificate checker tool.
An SSL/TLS checker verifies the security of your connection by examining the TLS (Transport Layer Security) version, HTTP protocol version, and encryption details. It confirms whether your browser is using modern, secure encryption standards.
Visit this page to instantly see your connection security details. The tool automatically detects your TLS version, HTTP protocol, and provides a security rating. No input required as it analyzes your current connection to HackMyIP.
SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are encryption protocols that secure data transmitted between your browser and websites. TLS 1.3 is the current standard, offering the strongest security and fastest handshakes.
TLS 1.3 is recommended for the best security. TLS 1.2 is still acceptable. TLS 1.0 and 1.1 are deprecated and considered insecure. Most modern browsers only support TLS 1.2 and 1.3.
HTTP/2 uses TCP connections and supports multiplexing (multiple requests over one connection). HTTP/3 uses QUIC (UDP-based) for faster connections, better handling of packet loss, and improved performance on mobile networks.
