Why would you need PowerMgmt or TrustedUI capabilities?

I know two reasons: Because you did not want to check the set of capabilities your application actually needs you selected all 13 that you can get through Express Signed. AND you have a DLL which you load to a system process so your applications needs All-TCB (all except TCB capability)....

Why do I need manufacturer capabilities?

Have you noted a new wiki entry? http://wiki.forum.nokia.com/index.php/Sensitive_Applications It's all about where sensitive capabilities are needed and types of applications which have actually received the capabilities. Do you think such information is useful? Risto

APIs vs. Capabilities relaxing the security?

Have you noticed an interesting discussion thread: http://discussion.forum.nokia.com/forum/showthread.php?t=103255 ? We are seeking things which you have noticed in the areas of APIs placed behind weird capabilities or too strong capabilities. If you have come accross with such then the...

SSL certificates in S60 3.0

There has been some discussion in various forums about how to install a SSL certificate to S60 3.0 device. I asked around and I'm planning on creating a short document around the subject. But first the quick way of sharing information - a blog! I hope this will provide some clarity to the...

Why to fail Symbian Signed

See what Symbian has listed: http://developer.symbian.com/wiki/display/sign/Common+causes+for+failure+during+the+Symbian+Signed+Test+Process What do you think? Are you having the same experiences?

Certificates and validity periods

Have you noticed the validity period of different certificates? If you create a certificate with makekeys it is valid for a year. A Symbian DevCert is valid for a half a year. ID certificates (like the VeriSign ACS Publisher ID) are commonly valid for a year. This brings in interesting...

Starting the application at device boot

Latest news! I recently came accross with knowledge that using recognisers to start your application at the start up may make a S60 3rd edition phone a vegetable. This happens in totally random order, so I don't recommend on testing it. Well, starting up an application at device boot with...

Symbian Developer Certificates changed

Some changes happening! Symbian has loosened the requirements in the Symbian Developer Certificates. Now a developer can also access ReadDeviceData, WriteDeviceData and TrustedUI without the VeriSign ACS Publisher ID for one IMEI (device). An other improvement is the number of IMEIs. With the...

MTMs

MTM, an other abbreviation to learn. This time it means a Message Type Module. In S60 3rd edition I have herd of two of them: 1. Server-side MTM, the application is visible in the Messaging UI - nice feature for a e-mail client 2. Client-side MTM, the application is visible in the "Send...

Installing untrusted application requiring capabilities to S60 3rd edition

I found a freeware game S-Tetris 2, being an old fan of the game I just got to have it. So off from download to installation, SIS file in and installation started. The application was not trusted so I paid attention to what was my E61 going to say about it. "...untrusted and may be harmful...

Opportunities in the 3rd edition

Had bumped into quite many interesting requests lately. Assumptions that a capability is needed, even though it is not needed. I felt that it is good to raise them up here, in case someone happens to read this blog. The user can grant LocalServices ReadUserData WriteUserData...

Symbian Platform Security, capabilities and application security

I asked a colleague about what should I write in my first blog. He replied “Something positive”. But then again he was getting something positive to his cup – fresh coffee on Monday morning, I guess that’s where the analogue came from. Last week we solved a...
