Since the test for TLS 1.2 in `run_protocols()` now uses `tls_sockets()` whenever `$ssl_native` is `true` (i.e., there is no longer a requirement for `$EXPERIMENTAL` to be true as well), the `$EXPERIMENTAL` flag should no longer be checked if the return value is 1.
When a list of cipher suites is being displayed using `neat_list()`, testssl.sh shows the cipher suite's OpenSSL name and (in most cases) the RFC name as well. However, in all other cases only the OpenSSL name is shown.
This PR adds the option to have cipher suite's RFC names shown instead of the OpenSSL name, by including `--mapping rfc` in the command line. [Note: if the cipher-mapping.txt file cannot be found, then the `--mapping rfc` option is ignored and the OpenSSL names are shown.]
This PR seems to be related to issue #9, but #9 may be been referring to the output created by `neat_list()`.
This PR addresses the issue raised in #623. This PR is based on the function `out_row_aligned_max_width()` that I proposed in #623, but the `out_row_aligned_max_width()` in this PR is a little different. It takes a fourth parameter, which is the function to use to print each word in the text string to be printed. This is used in `run_pfs()` so that the "Elliptic curves offered" can be printed using this function (some servers support 25 curves), while still having the curves printed using color-coding to indicate the quality of each curve.
I somewhat arbitrarily have each line wrap at 120 characters, but that could be changed (e.g., to `$TERM_WIDTH`).
In the revised code that was created to address #587, nothing is printed after "OCSP URI" if there is neither an OCSP URI nor a CRL URI. Instead, "--" should be printed.
I still believe that there is an inconsistency in the reporting of the output, however. At the moment, the "Certificate Revocation List" and "OCSP URI" lines indicate it is acceptable as long as the certificate contains either a CRL URI or an OCSP URI. However, the "OCSP stapling" line reports a minor finding if an OCSP response was not included in the server's reply. Shouldn't we just assume that if the certificate doesn't include an OCSP URI, then it wouldn't be possible for the server to obtain an OCSP response to staple to its reply? If so, then it seems that no OCSP stapling should only be considered a finding if an OCSP URI is present.
This PR fixes issue #601.
The fix for OCSP URLs was easy. I don't entirely understand the first `awk` command in the line to extract the CRL URLs, but I tested it on several certificates and it seems to work correctly (ensuring that the only "URI" lines in the input to the second `awk` command are from the CRL Distribution Points extension).
