SSL / TLS Cipher Suite & Security Protocols Reference

Comprehensive reference of modern SSL/TLS cryptographic cipher suites: TLS 1.3 AES-GCM, ChaCha20-Poly1305, key exchange algorithms (ECDHE), and PFS forward secrecy.

100% Free & Unlimited Private Client-Side ($0 Server Cost)

TLS 1.3 Ciphers (Modern Standard)

  • • TLS_AES_256_GCM_SHA384
  • • TLS_CHACHA20_POLY1305_SHA256
  • • TLS_AES_128_GCM_SHA256
  • • TLS_AES_128_CCM_SHA256

TLS 1.2 ECDHE Ciphers (PFS Ready)

  • • ECDHE-RSA-AES256-GCM-SHA384
  • • ECDHE-RSA-AES128-GCM-SHA256
  • • ECDHE-ECDSA-AES256-GCM-SHA384
  • • ECDHE-ECDSA-CHACHA20-POLY1305
Deprecated Insecure Ciphers (Avoid):

RC4, DES, 3DES, CBC-mode ciphers vulnerable to Lucky13/POODLE, MD5, and SHA-1 signatures. Never use SSLv2, SSLv3, or TLS 1.0/1.1 on modern servers.

What is SSL / TLS Cipher Suite & Security Protocols Reference?

The SSL / TLS Cipher Suite & Security Protocols Reference on NexTools is an interactive network, browser, and hardware diagnostic tool designed for web developers, IT professionals, and privacy enthusiasts. Engineered to operate directly in modern web browsers, it provides instant diagnostic analysis with zero tracking, zero telemetry, and maximum computational security.
