Install a web certificate (*.cer) on an Android device

---

Hi,
To gain access to WIFI at university I have to login with my user/pass credentials.

The certificate of their website (the local home page that asks for the credentials) is not recognized as a trusted certificate, so we install it separately on our computers.

I want to know how to install such certificates on Android, I have HTC magic and I came through this question which seems the same problem but the solution is specific to exchange server and not the browser http://forum.xda-developers.com/showthread.php?t=551512

This is the details of installing the certificate from the university's page [LINK]

if you are rooted, download wifi helper (its free) from market and it should help you configure your wifi with custom cert files.

Hey,

I stumbled onto this topic as I had the problem (but on the Droid, Android v2.0). I then figured out how to do it and made a tool to make it easier. I call it RealmB's Android Certificate Installer. It basically gives your Android's web browser the correct HTTP headers to make it launch the CA certificate installation wizard.

Hope this helps,
Brian

I used Android's built-in certificate manager.

1. Just drop your certificate file onto the sdcard/download folder.
Note: Keep in mind the manager looks for .p12 and/or .crt files. I had a .cer file, but it was PEM formatted so I simply changed the extension.

2. Go to settings-> Security & Privacy -> Install from SD Card
Note: I use the MIUI rom, so millage may vary a bit on other roms

Done! Enter your credentials password, or create a new one if you didn't have one already, and you're all set!

Thanks MrNago

renaming .cer to .crt really makes me being able to install it. Life can be so easy ... (MIUI 2.3)

I was looking for a way to do this exact thing, and found a (potentially) easier way to install the certificate. If you have access to a web site, you can just put the .crt file on it, go to the site, click the file and voila... It installs on the device.

Worked like a charm since I do not have an SD card with me, but I needed to install the certificate.

Thanks for the comments above. I had a .cer file, and renaming it worked like a champ as well.

Thanks, this works.

To install a browser certificate into a pre-ICS ROM, use Portecle to add it to /system/etc/security/cacerts.bks.
Notes:
- obviously, ROOT is required to do this
- the keystore p/w is changeit
- In ICS a certificate can be simply added via Settings

The problem is only old stock browser sees installed certificate. This browser doesn't exist on Jelly Bean for Nexus 7. Google Chrome is default browser here.

Anyone knows a solution to this?

Thanks

The solution could be to wait until the bug in Chrome is fixed.
