As jsonID is not set by run_crime, make the fileout invocation for
servers supporting only TLS 1.3 use the literal "CRIME_TLS" instead.
Previously running testssl with CSV or JSON output would produce an item
with the wrong ID.
Currently run_server_preference() will stop if it cannot determine whether the server enforces a cipher preference order.
This commit changes run_server_preference() so it will continue running even if this case, so that the list of ciphers supported with each TLS protocol is provided. Since it is not known whether the server enforces a cipher order, the list of supported ciphers is ordered by strength.
See #2127. the line seems very long though.
Note: this was previously commited as #2184 but as there were two mistakes
and one other thing which could be improved I decided to make a hard reset.
Apologize if it caused inconvenience.
OpenSSL 3.0.0 and later supports specifying the FFDHE groups from RFC 7919 in the "-groups" (or "-curves") option of s_client.
This commit modifies find_openssl_binary() to check whether $OPENSSL supports this. This information is then used by run_client_simulation(), if client simulation testing is being performed using $OPENSSL. If the "curves" for a client include FFDHE groups, then they will be included in the simulated ClientHello.
On macOS indark mode the git tag in grey wasn't visible. It was
changed now to light grey but it has to be tested how it looks
on a white terminal background.
Also CVS variables were removed which had no meaning.
In rare? occassions where the STARTTLS FEAT request only displays AUTH instead
of AUTH TLS, testssl.sh fails as it cannot upgrade to TLS.
Required by RFC 4217 is only AUTH ("MUST"), AUTH TLS is optional ("should"), see section 6.
This commit relaxes the presence of TLS after AUTH and it fixes#2132.
This commit fixes testssl.sh's calls to the "$OPENSSL ciphers" command.
The main issue it fixes is when actually_supported_osslciphers() is called to get a list of non-SSLv2 ciphers supported by $OPENSSL. With OpenSSL 1.0.2, the "-tls1" option needs to be used to exclude SSLv2 ciphers. With LibreSSL, the "-tls1" option may be provided, but it has no effect. With OpenSSL 1.1.1 and newer, the "-tls1" option causes TLSv1.2-only ciphers (e.g., AES256-SHA256) to be excluded (when the "-s" option is also used).
This commit fixes the problem by allowing "-no_ssl2" to be provided as an option to actually_supported_osslciphers(). For versions of $OPENSSL that support SSLv2, "-no_ssl2" is replaced by "-tls1". For versions of $OPENSSL that do not support SSLv2, "-no_ssl2" is simply removed.
This commit also changes openssl2hexcode() to include the "-tls1" option when $OPENSSL supports SSLv2, since openssl2hexcode() should only return a non-SSLv2 cipher.
determine_optimal_sockets_params() makes two attempts to send a TLS 1.2 ClientHello, with each attempt trying 127 ciphers. However, this leaves 97 ciphers from etc/cipher-mapping.txt that are not tried, most of which use ARIA or CAMELLIA. This commit adds a third attempt a send a ClientHello that offers these 97 remaining ciphers. This helps to ensure that support for TLS 1.2 is detected and that later calls to tls_sockets() work, even if the server only supports the ARIA/CAMELLIA ciphers that are not included in TLS12_CIPHER or TLS12_CIPHER_2ND_TRY.
