About Certificates
You can use digital certificates to identify the computer for network
access or authentication to servers. To use a certificate to identify your
device, you must install it in the trusted credential storage on the
computer.
Android supports DER-encoded X.509 certificates saved in files with a
.crt or .cer file extension. To install a valid certificate with a .der or
other extension, you must change the extension to .crt or .cer to install
it.
Android also supports X.509 certificates saved in PKCS#12 key store
files with a .p12 or .pfx entension. To install a valid key store file with
another extension, you must change the extension to .p12 or .pfx to
install it. When you install a certificate from a PKCS#12 key store,
Android also installs any accompanying private key or certificate
authority certificates.
Load a Certificate
To use a certificate, you must install it in the trusted credential storage
on the computer.
1 Copy the certificate or key store from your PC to a microSD card.
2 Install the microSD card in the computer and turn the computer
on.
3 Start the Settings app and tap Security > Install from SD card.
4 Tap the name of the certificate or key store to install it. If
prompted, enter the key store password and tap OK.
5 Enter a name for the certificate and tap OK.
Note: Apps such as Email and Browser that support certificates allow
you to install certificates directly from within the app. For more
information, see the Help that comes with the app.
