Blackberry OS 10 and LetsEncrypt

Saturday, March 19th, 2016

The great service at offers certificates for everybody to encrypt their websites with (meaning to offer HTTPS).

Unfortunately, the Blackberry OS 10 Browser does not yet ship with the certificates used to sign the websites so you either have to go back to unsecure HTTP or in case of HSTS you are unable to view the webpage.

Hopefully, there will be an update to BBOS 10 soon to fix this issue.

Luckily, one does not have to wait for the update but can manually import the needed certificates.

Head over to and download the PEM format of:

  • ISRG Root X1
  • Let’s Encrypt Authority X1 (IdenTrust cross-signed) and Signed by ISRG Root X1
  • Let’s Encrypt Authority X2 (IdenTrust cross-signed) and Signed by ISRG Root X1
  • Also get the DST Root CA X3 by copying the text to a textfile, remove the whitespace at the end and surround it by


    copied text here

    -----END CERTIFICATE-----

    each on a new line. Save that file as dst_root_ca_x3.pem

    After copying all files to the device (e.g. via SD card), go to Settings -> Security and Privacy

    Securiy and Privacy

    -> Certificates


    and Import


    all 6 files (5 from LetsEncrypt and 1 from IdenTrust).

    Thats it, open your browser and try it out.
