Fix for SSL certificate error in SBB app on iOS 13 beta
Update: As of today, this workaround is no longer needed. SBB updated their app with proper certificate.
- On your Mac, enter the following command in Terminal:
openssl s_client -showcerts -connect p1.sbbmobile.ch:443
- As an output, you will get two blocks of base64-encoded text delimited by
-----BEGIN CERTIFICATE-----and-----END CERTIFICATE-----. Copy the second block (including those delimiters). - Open a new plaintext document in TextEdit or any other text editor, paste the copied code and save it as sbb_ca.pem
- (Optional) Double click on the new certificate to validate that you created a valid certificate file. Keychain Access should open and when you click on View Ceritificate, you should see:
*.sbbmobile.ch
Root certificate authority

"*.sbbmobile.ch" certificate is not trusted
- AirDrop the certificate file to your iPhone/iPad running iOS 13 beta
- Go to Settings and Install the certificate (There will be a new button at the top of the Settings page, between iCloud and Airplane Mode, asking you to finish the installation.)
- Go to Settings > General > About > Certificate Trust Settings and enable the newly installed certificate
