wolfSSL has announced TLS 1.3 support for sniffer users. The wolfSSL sniffer can be used to passively sniff SSL/TLS traffic including https traffic. wolfSSL supports industry standards up to the current TLS 1.3, for which we were the first commercial implementation. Our sniffer users benefit from this compatibility with the latest TLS protocol. Users can download wolfSSL 4.8.0 to access TLS 1.3 sniffer support: https://www.wolfssl.com/download/.
For TLS v1.3, all cipher suites use a new ephemeral key for each new session. Only Perfect Forward Secrecy (PFS) ciphers are allowed, whereas typically a static RSA ciphersuite would be used. In order to solve this, we added a “static ephemeral” feature, which allows setting a known key that is used for deriving a shared secret. The key can be rolled periodically and synchronized for internal or test environments. We’ve also created a Key Manager for secure distribution of ephemeral keys based on the ETSI TS 103 523-3 specification.
