### What is TLS\_ECDHE\_RSA\_WITH\_AES\_128\_GCM\_SHA256?



TLS\_ECDHE\_RSA\_WITH\_AES\_128\_GCM\_SHA256 is the most common TLS 1.2 cipher suite, providing perfect forward secrecy through ECDHE (Elliptic Curve Diffie-Hellman Ephemeral) key exchange. RSA is used for server authentication (certificate signature). AES-128-GCM provides authenticated encryption. Forward secrecy ensures that compromise of the server's private key does not compromise past session keys. This cipher suite is supported by all modern browsers and servers. It is the recommended choice for TLS 1.2, offering strong security and excellent performance. However, TLS 1.3 cipher suites are preferred when available.



 

### Role in JA3 Fingerprinting



The **TLS\_ECDHE\_RSA\_WITH\_AES\_128\_GCM\_SHA256** cipher suite is part of the TLS Client Hello that JA3 analyzes. Cipher suite order and selection are key indicators of browser type and version.

**JA3 Format:** `TLS_VERSION,CIPHERS,EXTENSIONS,CURVES,POINT_FORMATS`

Different browsers prioritize different cipher suites (Chrome prefers ChaCha20 on mobile, Firefox prioritizes AES-GCM, etc.), making cipher suite ordering a reliable fingerprint.
