Certificates
Digital certificates are used to identify your smartphone in secure network connections. You
require a certificate for VPN or WLAN connections for example, or for authentication with email
servers, browsers or other apps. Some certificates are already stored on your phone by default.
You can install further certificates.
Supported formats:
•
DER coded X.509 certificates with file extensions .CRT and .CER.
•
X.509 certificates in PKCS#12 keystore files with file extensions .P12 and .PFX. If you install a
certificate from a PKCS#12 keystore file, the corresponding private key certificates or
certification authority (CA) certificates are also installed.
Files with different file extensions cannot be installed. Change the file extension if required.
