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 extension. 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.
