Importing Certificates - Nexus One Android Development

I need to import a certificate for my WIFI. I can get this as a PEM or DER format certificate from our admins, which I can use on anything else from a laptop to a pda.
On the Nexus the certificate needs to be .p12 files (PKCS#12). I do not have one of these, nor can I get one, nor can I find a way to convert the current PEM/DER to one of these.
How do I do this? It seem pointless if the nexus requires a different format than that provided to people to work with all other devices. Admins are not going to start issuing a special format, just for nexus users, Especially when that format seems to need a private key in addition and/or another password too.
Anyone else managed to do this?

I installed a certificate (a .crt file) by opening it with the web browser (via HTTP). You could also try opening it in Astro or another file manager.

A lot of people have complained about this. Apparently you have to import it from the web browser. File and gmail apps don't seem to know how to handle the certs.
You can forward it to your gmail account then use the web browser to get to gmail and import it from there.

Hi Guys,
I don't mean to hijack the thread, I've been trying to find the full encryption standards and protocols supported by the nexus one and have not had much luck. I presume you guys might have an idea.
Anyone got a link ? Thanks for your help. Ash.

I've tried opening with a few file browsers, no luck as they refuse to open them, tried various ways of opening with web browsers, no luck as all they want to do is save them, and then the file browsers dont want to open. Also tried email and opening through the web or client. No luck.
Can you guys break it down how you got it to work ?
Thanks
Ash.

Anyone know how to load a .crt and .ca certificates on the nexus one ?
I've tried doing everyway with and without the certificates.
Thanks
Ash.

Just tried uploading a .DER cert to my personal FTP and goto it via the browser and it simply opened it like a text file. .P12 files are recognised by the browser fine and the user is prompted for the passkey but that is expected as .P12 seem to be the only type of cert that works on Android.

You could try to manually modify wpa_supplicant.conf . Depending on the network configuration this may vary. This is the same way you would do it in Linux. I remember I did this in my G1 ( I dunno if you need root, my G1 was rooted anyway), but the location of the file was not in /etc like it is usually in most Linux. My conf looked like this:
network={
ssid="somenetworkWPA"
proto=RSN
key_mgmt=WPA-EAP
pairwise=CCMP
eap=PEAP
identity="[email protected]"
password="pass"
phase2="autheap=MSCHAPV2"
ca_cert="/sdcard/mycert.der"
}
There are plenty of samples and explanations around the net about changing this file. Hope this helps.

It's /data/misc/wifi/wpa-supplicant.conf. It's owned by wifi:wifi with permissions 770. So it appears you'll need to be root.
