I have a server which is configured to use TLS 1.0, 1.1 and 1.2. The server is configured with a certificate siged by SHA-512. The server supports only these cipher suites:
• TLS_RSA_WITH_AES_256_GCM_SHA384 • TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256 • TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 • TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 • TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
The client (browser) requested for the handshake and offer these cipher suites:
• TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 • TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
The server has accepted
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 and presented it's certificates, which has has algorithm identifier
Does this mean the browser is able to verify SHA512 cert without any cipher suites in common?
