"Since Chrome 49, <keygen>'s default behaviour has been to return the empty string, unless a permission was granted to this page. Removed in Chrome 57."

"IE/Edge do not support <keygen> and have not indicated public signals to support <keygen>. Firefox already gates <keygen> behind a user gesture, but is publicly supportive of removing it. Safari ships <keygen> and has not expressed public views regarding its continued support."

Generating keys still works for me with
Firefox 57.0.4 (64-Bit, Linux) installed in openSUSE Leap 42.3.

I went through the process of generating keys and CSR in openssl then
submitting CSR through the advanced section of “New Certificate” and it
worked perfectly for me (using current Firefox). I have to say it is not a
simple solution and it certainly requires a much higher level of technical
skill than the browser solution, but it does work.

I did some research on possible tools to simplify the process and I have a
proposal. As far as I can see the browser route is dead, so we need to look
elsewhere. I am looking at the possibility of a desktop app that would
generate keys and CSR then connect to the cacert.org <http://cacert.org/>
site through a screen scrape library to submit the CSR and store the
certificate back in a local keystone. The one extra step required is to
import the certificate into browsers/mail clients, which should not be
difficult for most people. I am starting work on a cross-platform proof of
concept which I hope to be able to demonstrate in a few weeks.

"The browser route is dead" - indeed, so solutions running natively on the platforms are necessary.
A technical discussion thread was started here:
https://lists.cacert.org/wws/arc/cacert-devel/2018-04/msg00000.html

Supporting many platforms can be challenging. Because a simple solution is better than none, I'd prefer to have console-based scripts using on-board tools such as openssl (usually available for UNIX-style systems) or certreq (on standard Windows since many years - Vista?) as a baseline. Automating the CAcert certificate request page is not essential for the simple tool variant, where a graphical, more powerful and comfortable variant can complement it and doesn't need to cover platforms on an equal level or have the same robustness.

For UNIX-style systems I created a shell/openssl based solution as proof-of-concept here:
http://70t.de/download/ , file with pattern cacert_client_certificate_<date>.tar.xz (at time of writing cacert_client_certificate_2018-04-11.tar.xz )

I tried out cacert_client_certificate_2018-04-09.tar.xz. Thanks for creating it. I have a few suggestions/remarks about it.


A)

Multiple inputs of a passphrase are required:
  1. Unlock the key (from the file generated in the first task)
    -----
  2. Set a passphrase for the new certifcate file
  3. Repeat (confirm) the passphrase from 2. above
Input area (sequence of 3 passphrases): [1. Unlock key password]
Enter Export Password: [2. passphrase for new cert]
Verifying - Enter Export Password: [3. repeat 0000002]

The three numbered items should be explicitly numbered and named in each of the prompts that come after. The first prompt of "Input area (sequence of 3 passphrases): " does not indicate that you are supposed to type on the "passphrase to protect the generated key" when generating the RSA private/public key pair.


B)

If ready, press enter to open the certificate with the browser for import.

[
In the case of Firefox 59.0.2 (64-bit), Ubuntu 16.04.4,
a dialog box will ask
What should Firefox do with this file?
(*) Open with [View file (default]
( ) Save File
[ ] Do this automatically for files like this from now on.
[OK]
Questions about passphrase and labels eventually displays
the certificate details but is not imported. I had to go to Firefox's Certificate Manager and
manually [Import...] the newly created new_certificate_$USER.pfx file.
You will need to unlock the .pfx file with the
"Enter Export Password: [2. passphrase for new cert]" from above.
]

Oops. That note should have gone to the mailing list where cacert_client_certificate_2018-04-09.tar.xz was posted. There is no edit/delete.
