20191025 - Firefox remove Keygen support

The version 69 of Firefox released on the 3 September 2019 removed support for <keygen> tag.

It allows a browser to generate a private key and a CSR from a form. The key is then stored in the browser keystore to facilitate the resulting certificate installation.

Our forms use the <keygen> tag during the order of certain client and code signing certificates.

What consequences?

  • You'll have to use a browser capable to generate a private key and a CSR to use our client and code signing certificates order forms (if you don't generate them on your own).

  • You'll then have to use the same browser to download your certificate

  • Finally, if needed you'll have to export your certificate and import it on the wanted tool

Which products are impacted?

Client and code signing certificates requiring a CSR:

  • Thawte Code Signing
  • Symantec Code Signing

  • TBS X509 Email Novice
  • TBS X509 Sign & Login
  • TBS X509 Email Professional

Which browsers are compatible?

INTERNET EXPLORER
(via the use of CertEnroll and XEnroll ActiveX control
SAFARI
FIREFOX 69+
MICROSOFT EDGE
GOOGLE CHROME 57+
OPERA

What impact for the currently valid certificates?

None. Once the certificate is issued, it is installed with its private key in your browser keystore. They won't be impacted.
