You may have heard about Let's Encrypt. If not, go there and check it. You can have SSL certificates for your servers for free, so there is now no excuse for not using https by default.
But Let's Encrypt certificates are not yet trusted in all browsers/systems. And one of those is my beloved BlackBerry OS 10. Here comes the good news: there is a way to fix it!
Go to https://letsencrypt.org/certificates/ and download https://letsencrypt.org/certs/isrgrootx1.pem and https://letsencrypt.org/certs/letsencryptauthorityx1.pem.
And then go to https://www.identrust.com/certificates/trustid/root-download-x3.html and copy certificate body to text editor. You need to prepend
-----BEGIN CERTIFICATE----- and append
-----END CERTIFICATE----- so it looks like this
and save it to file (such as
Then simply import these three files on your Blackberry phone via Settings - Security and privacy - Certificates - Import.
After doing so, your Blackberry should start trusting all Let's Encrypt certificates.

works, except for one site

Thanks for this tip. It works for most sites except for this one: osca.hs-osnabrueck.de
Do you have any suggestions,

Its possible that site is signed with one of the other intermediate certificates than the ones listed in this article. To ensure you cover ALL the bases you actually need to install seven certs from Let's Encrypt, and one from IdenTrust. As I mention in another post here you can install all eight required certs with just two click with my free multiCERT app. https://appworld.blackberry.com/webstore/content/59999147/

A nightmare..... steps, coding reminds me of DOS, APL, COBOL, Fortran programing language.
I'll skip steps and hopefully find a "package", bundle from BlackBerry to update BlackBerry Classic.

That's a great post, thanks.
But as mentioned above, now there's a better way - a new app multiCERT that will install all 8 required certificates with just a single click. Kudos to its author.

Hi Martin, I've imported five certificates from Firefox to my Bold 9900, but I'm still getting certificate problems. Could you provide a list of the certificates you included in the BB10 app?

not sure whats going but some how I manage to fix the site that is bugging me with the same issue, the first two instructions could not be done because the phone would not trust the site I used another browser on the phone and then copied the file in the last instruction over to my phone and now it works without complaining. The application your speak of will not work on a passport it says "your device is not supported"
