I know, you might be thinking how did I come up with this??? Ah, nothing specific just read various documents about Android!!
And don’t be worried about installing a Security & Personal certificate, that’s easy like renaming a file hehehe…
Before starting about installation part, let me explain you why you are not able to install cer & pfx… It is not supported with that extension, that’s all..!!!
“Okay, so what should I be doing” is your question right?? Well here its goes, the secret: p
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.
After all the renaming of the certificate file, installing certificates on your handheld is very easy. You don’t even need to search certificates on your phone, Android finds and installs for you; see that easy it is!!
How to install the certificates??
On your Android devices, click the Menu!
Go to “Settings”
Click “Location & security settings”
Scroll down a bit and click “Install from SD card”, and follow few more steps, that’s all we are done!!
