Rearrange code so that in the case of just a single test, `parse_hn_port()` is not called earlier than it was previously unless it needs to be called in order to create the HTML file name.
Doing this ensures that the banner is displayed even if the `$URI` cannot be parsed (except in the case that the `$URI` needs to be parsed in order to create a file name) and that any error messages created by `parse_hn_port()` will be included in the HTML, if possible.
Add option for testssl.sh to create the HTML file name. If testssl.sh creates the file name, then, in the case of mass testing, a separate HTML file is created for each test (i.e., for each line in the file provided to `--file`).
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()`.
Gray should appear for COLOR=1 or COLOR=2.
Since `pr_grey()` is basically the same as `out()` for COLOR=0, `mybanner()` should just call `pr_grey()` without checking the value of `$COLOR`.
Change `emphasize_stuff_in_headers()` to use olive and bold olive rather than brown and yellow. This matches what `aha` creates and appears similar to what is displayed in the terminal on a Mac. Also, yellow text is very difficult to read.
Found more places where output should only go to terminal, or where it was only going to the terminal (e.g., printf) but should also be in the HTML. Also added the ability to include active URLs in the HTML output.
To Do: Handle automatic generation of HTML file name and support for parallel testing.
Introduced "trick" so that if the `--file` option is used, `html_header()` will only be called once before anything is printed and `html_footer()` will only be called once after all printing is complete. With this, `html_header()` now delete the output file if it exists.
Also introduced the `html_reserved()`, which is called for all text to be sent to `out_html()`. `html_reserved()` converts any HTML reserved characters (", ', &, <, >) to their corresponding entity names (", ', &, <, >).
This PR addresses the issue raised in #623. This PR is based on the function `out_row_aligned_max_width()` that I proposed in #623, but the `out_row_aligned_max_width()` in this PR is a little different. It takes a fourth parameter, which is the function to use to print each word in the text string to be printed. This is used in `run_pfs()` so that the "Elliptic curves offered" can be printed using this function (some servers support 25 curves), while still having the curves printed using color-coding to indicate the quality of each curve.
I somewhat arbitrarily have each line wrap at 120 characters, but that could be changed (e.g., to `$TERM_WIDTH`).
For the most part I used the RGB values for xterm from https://en.wikipedia.org/wiki/ANSI_escape_code#Colors for the HTML colors, but with a few exceptions. For example, I did not use "yellow" for `pr_svrty_low()`, since that color is very difficult to read. I also used a different color for `pr_svrty_medium()` so that `pr_svrty_medium()` would appear more red than `pr_svrty_low()`.
These color choices could use more adjustment.
This PR adds the option to generate HTML. The code was created as follows:
* For each output function (`out()`, `outln()`, `pr_liteblue()`, etc.) I created two functions: one that just outputs to the terminal and one that outputs to the terminal and to the HTML file (if an HTML file is to be created).
* I modified the code so that any output that should appear in the HTML file in addition to being displayed on the terminal is sent through one of the display functions: out()`, `outln()`, `pr_liteblue()`, etc.
* I created a new function `retstring()` to use in place of `out()` when a function is creating a string to be "captured" by the calling function.
* I modified the code so that no string returned by a function includes color-coding escape characters.
