Certificates
Digital certificates are used to identify your tablet in secure network connections. You will
require a certificate for VPN or WLAN connection or for authentication with e-mail servers,
browsers or other apps. Certain certificates are already saved to your tablet by default. You can
install further certificates.
Supported formats
u
DER coded X.509 certificates with file extensions .CRT or .CER.
u
X.509 certificates in PKCS#12 keystore files with file extensions .P12 or .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. Edit the file extension if required.
