Expanded cipher support in FIPS-CC mode (7.6.3)

FortiWeb's FIPS-CC mode now supports the ECDHE-RSA-AES128-GCM-SHA256 and ECDHE-RSA-AES256-GCM-SHA384 ciphers. These elliptic curve Diffie-Hellman (ECDHE) ciphers enhance secure communication by providing forward secrecy and authenticated encryption with AES-GCM. This update improves compliance with stringent security standards while maintaining high-performance encryption for SSL/TLS traffic.
