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



TLS\_ECDHE\_ECDSA\_WITH\_AES\_256\_GCM\_SHA384 is the high-security variant combining ECDSA certificates, ECDHE key exchange, and AES-256-GCM encryption. This provides 256-bit security throughout: ECDSA uses P-256 or P-384 curves, ECDHE uses matching curves, and AES-256-GCM encrypts data. SHA-384 is used for key derivation. This cipher suite is suitable for highly sensitive applications requiring long-term secrecy. The combination of ECDSA certificates and AES-256 is recommended for government and military use (NSA Suite B at the 256-bit security level).



 

### Role in JA3 Fingerprinting



The **TLS\_ECDHE\_ECDSA\_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.
