S40 Support for CA Certificate Import

Someone requested S40 support for the CA certificate Import 'Wizard'. This 'tool' is being used over 50 times a day, so I guess that it works :-). Knowing that it is being used, I added S40 support (theoretically that is, since I don't have such a device).

Just select the type of device you have (S60 or S40 based). Depending on the selection the extension, and MIME type will be changed.

The S40 devices expect a different MIME type (application/vnd.wap.hashed-certificate). So I added this MIME type to my webserver and associated it with .cer files. More information on this page.

Note, that you need to upload a WPKI certificate instead of a normal one. I'm still figuring out what the exact difference is, so I might do a conversion....

UPDATE: import on a S40 doesn't work, so don't bother.

I get this certificate error called "untrusted certificate received from sever" for my nokia e50. Please help. Thanks,

Hello Tejas,

what format are you using for this certificate? Can you open the certificate with notepad? If so, can you port the contents of the certificate (FYI this isn't a security risk, unless you don't want other people to know what domainname you're using)

I can't install the certificate on my cell phone 6120c, it's S60 3rd fp1 phone.

I am getting crazy..
I have a nokia 6131NFC a buy from thwate a code signing certificate.
I sign the midlet following the procedure.
But when i start the application on the phone i get a error (no certificate on phone or sim) ??
I Try to use your tool to send a server certificate from Thwate, but is it impossible to set that certificate for the application.
If i go on teh application details, i read no certificate.
So i do not understand if is a problem to signe the midlet (if i wrong procedure) or if is a telephone problem.
In the first time Thwate said the problem was the phone because there is not the route certificate.
So i try to install the roote certificate, but nothin change

@michele:
I don't know hich certificate you imported. You mentioned the thawte server certificate, but code signing certificates are signed by other CA certificates. You should use the code signing root certificate from thawte, and import that one in the phone.
I must mention that this is the first time I see this question pop-up, and I have no experience with code-signing, so it's purely theoretical.
