A

Android allows you install additional certificates from files you received someone else or you generated from some tools. But those certificate files must be in one of the following formats:

1. Android supports DER-encoded X.509 certificates, saved in files with a .crt or .cer file extension. If your certificate file has a .der or other extension, you must change or convert it to .crt or .cer or you won't be able to install it.

2. Android also supports X.509 certificates saved in PKCS#12 key store files with a .p12 or .pfx extension. If your key store has some other extension, you must change or convert it to .p12 or .pfx or you won't be able 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.
