https://api.dev.ssllabs.com/api/v3/getClients incorrectly indicates a highestProtocol of 771 (TLS 1.2) for clients that support TLS 1.3, which leads run_client_simulation() to incorrectly report "no connection" if the client would have actually connected using TLS 1.3.
This has been addressed by manually editing etc/client-simulation.txt to set the highest_protocol to 0x0304 for the clients that support TLS 1.3.
This PR modifies update_client_sim_data.pl to automatically apply the fix for clients that support TLS 1.3 in order to avoid a possible regression when etc/client-simulation.txt is updated.
When performing client simulations in "--ssl-native" mode, provide the client's list of supported curves to "$OPENSSL s_client" in order to make the results even more accurate.
This PR improves client simulation in "--ssl-native" mode:
* It changes ${protos[i]} to list the protocols that should be disabled rather than those that should be enabled, except in the case that the client only supports one protocol.
* It sets the values for ${tlsvers[i]}, which is used in run_client_simulation(), but was not defined.
* It adds a new variable, ${ciphersuites[i]}, that lists the TLSv1.3 cipher suites supported by a client.
Client simulation still produces false results in "--ssl-native" mode, but the results are better than before.
This fixes a bug which prevented the script from running properly. Also
the commit restores writing a correct comment header. In addition it
adds TLS 1.3 ciphers.
timeout: the TLS ticket check has a timeout, so that early on non-reachable hosts
are determined. If it is running into the timeout, it quits early. The
timeout is configurable via environment e.g. TIMEOUT=16 ./ticketbleed.bash <host>
Also other ports are allowed albeit it probably it is of limited use
Supplying no arg is now more user-friendly
This PR renames the cipher lists for `run_logjam()` in generate_static_cipher_lists.sh to align with their names in testssl.sh, as requested in #590.
I think these names are still open for misinterpretation, however, since its not clear whether "dh_cipher" refers to ciphers that use static DH keys, ephemeral DH keys, or both.
This PR adds a new utility that generates the various static cipher lists that appear in testssl.sh.
This utility serves two purposes:
* It can be run whenever new ciphers are added to cipher-mapping.txt to see if any of the lists in testssl.sh need to be updated. (This includes if cipher-mapping.txt is modified to add OpenSSL-style names for ciphers that are currently listed, but that have not yet been assigned such names.)
* It can be used as a reference in order to understand how each of the lists is defined.
