* Replace "! -z" with "-n"
* Replace "openssl' with "$OPENSSL"
* Redirect stderr output of $OPENSSL to /dev/null to supress "WARNING: can't open config file: /usr/local/etc/ssl/openssl.cnf" message (see #833)
* Remove unnecessary spaces from $GET_REQ11 string.
The CA browser form agreed on a validity period of 825 days or less
(https://cabforum.org/wp-content/uploads/CA-Browser-Forum-BR-1.5.3-redlined.pdf,
p4).
PR #1427 addressed that. However when an issuer signed/issued a certificate
with exactly 825 days, the check reported incorrectly that the life time
is too long.
This commit addressed that by adding a second to the calulation. Also the
output takes into account that it must be over ('>') 825 days, not '>='.
See #1070, kudos @poupas.
In addition it checks whether the first result was positive (in
terms of a finding). If so it does 4 rounds and checks the
result. So that other servers won't be penalized with 4 seconds.
derive-handshake-traffic-keys() uses the variables `derived_secret`, `server_write_key`, and `server_write_iv`, but they are not declared as local variables of the function. This PR fixes that.
to 1.1.0l and 1.1.1d. Seems that for the latter TLS 1.0 and 1.1
are disabled now, looking at the supported version extension.
However on the command line an s_client connect works. So
this commit need to be amended.
As noted in #1273, there are some environments that will not allow writing to /dev/stdout. PR #1277 was an attempt to address that problem (along with an unrelated problem), but it appears that work on #1277 has been abandoned.
At the moment, "/dev/stdout" is only used as a parameter to asciihex_to_binary_file (in fact, most calls to asciihex_to_binary_file specify "/dev/stdout" as the file parameter). This PR removes the file parameter from asciihex_to_binary_file (and so renames it asciihex_to_binary). In most cases, this just means removing "/dev/stdout" as a parameter to the function. In the few cases in which a parameter other than "/dev/stdout" was provided to asciihex_to_binary_file, this PR just uses a redirect (">" or ">>") to accomplish the same result as providing the output file to asciihex_to_binary_file().
Note that #1273 and #1277 raised the issue of trying to write to /tmp, and this PR does not attempt to address that.
This PR fixes two problems that occur when testing a server that supports TLSv1.3 using OpenSSL 1.1.1 in --ssl-native mode.
First, when testing whether the server has a cipher order, the value of $sclient_success is checked after each call to tls_sockets(), but $sclient_success. As the goal is just to verify that the connection was successful (and didn't downgrade), $? can be checked rather than $sclient_success. [When not in --ssl-native mode, this problem is masked since $sclient_success is set to 0 earlier in the function.]
The second problem is that line 6646 tries to copy "$TEMPDIR/$NODEIP.parse_tls13_serverhello.txt", but this file is currently only created (on line 6287) if tls_sockets() is used to determine the negotiated protocol. This PR fixes the problem by also populating "$TEMPDIR/$NODEIP.parse_tls13_serverhello.txt" when OpenSSL is used to determine the negotiated protocol.
The ciphersuites string for Safari 13.0 ends with a colon (':'). which causes OpenSSL to reject the command line when client simulation testing is performed in --ssl-native mode. This PR fixes the problem by removing the trailing colon.
