Working with secure certificates

If your organization’s VPN or Wi-Fi networks rely on secure certificates, you must obtain the certificates and store them in your phone’s secure credential storage, before you can configure access to those VPN or Wi-Fi networks on your phone.

If your network administrator instructs you to download the certificates from a website, you’re prompted to set a password for the credential storage when you download the certificates. For more information about working with credential storage, see Location & security settings.

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

Android also supports X.509 certificates saved in PKCS#12 key store files with a .p12 extension (if your key store has a .pfx or other extension, you much change it to .p12 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 contained in the key store.

Install a secure certificate from your phone’s USB storage or SD card

See Connecting to a computer via USB for information about connecting your phone to a computer and copying files.

Only the names of certificates that you have not already installed on your phone are displayed.

If you have not already set a password for your phone’s credential storage, you’re prompted to enter a password for it twice and then touch OK. For more information about credential storage, see Location & security settings.

You can now use the certificate that you installed when connecting to a secure network. For security, the certificate is deleted from the USB storage or SD card.
