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.
The wolfSSL sniffer can be integrated into any application using the existing sniffer API. Only five calls are required making it easy to integrate into any project. As a proof of concept, we added this support to Apache httpd to demonstrate real-time decryption of web traffic. Email us at facts@wolfSSL.com for access to the Apache httpd branch with sniffer and FIPS ready support.
Some of the main advantages of switching to TLS 1.3 from earlier versions of the protocol include quicker connection times due to reduced roundtrips during the handshake, reduced latency, improved session resumption, and more secure crypto by default. wolfSSL supports TLS 1.3 on both client and server side.
