Several limitations still apply:
- TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 is the only supported cipher suite
- Some tests are broken due to a failing assertion regarding bytestring
- No newly written tests for decryption (the patch was tested extensively for our paper)
- Several small open technical questions marked with FIXME
- Architecture in the ssl module might not be optimal
This also installs symlinks from "zeek" and "bro-config" to a wrapper
script that prints a deprecation warning.
The btests pass, but this is still WIP. broctl renaming is still
missing.
#239
This event is the replacement for ssl_application_data, which is removed
in the same commit. It is more generic, containing more information than
ssl_application_dataand is raised for all SSL/TLS messages that are
exchanged before encryption starts.
It is used by Bro internally to determine when a TLS1.3 session has been
completely established. Apart from that, it can be used to, e.g.,
determine the record layer TLS version.
This exposes the record layer version of the fragment in addition to the
content type and the length. The ordering of the arguments in the event
is the same as the ordering in the protocol message (first type, then
version, then length).
This also includes a slight change to the analyzer, no longer calling
the generate function if the event is not used.
triggered for the tls change cipherspec message.
Also - fix small bug. In case SSL::disable_analyzer_after_detection was set
to F, the ssl_established event would fire after each data packet after the
session is established.
