### What is TLS\_ECDHE\_RSA\_WITH\_AES\_256\_GCM\_SHA384?



TLS\_ECDHE\_RSA\_WITH\_AES\_256\_GCM\_SHA384 is the 256-bit variant of the most popular TLS 1.2 cipher suite, providing enhanced security for sensitive data. It combines ECDHE for perfect forward secrecy, RSA authentication, and AES-256-GCM for encryption. SHA-384 (instead of SHA-256) is used for key derivation and HMAC operations, providing additional security margins. This cipher suite is commonly used in government, healthcare, and financial applications. The performance penalty compared to AES-128 is approximately 40%, making it less suitable for high-traffic websites.



 

### Role in JA3 Fingerprinting



The **TLS\_ECDHE\_RSA\_WITH\_AES\_256\_GCM\_SHA384** 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.
