String cipher

[tkatva]

I would like to implement a class as part of my application that would encrypt given string using AES. This application should run on Symbian 3 devices, so the targeted Qt framework would then be 4.6.4?

I have read somewhere that Qt doesn't have a cipher, but has anyone some experience on other open source C++ ciphers? (Like Crypto ++) can you compile those to Symbian platform?

Any suggestions on how to encrypt and decrypt String with AES would appreciated.

Thank you

Symbian has built-in crypto support. You don't want to use an open source cipher if you might be subject to US (or possibly EU) export restrictions -- you want to use something that's pre-approved.

See http://wiki.forum.nokia.com/index.ph...ptography_APIs

Can I use these Symbian Crypto features with Qt? Does anyone know if Qt will have some ciphers implemented in future releases ?

I don't know why Qt doesn't include interfaces to the system's embedded crypto features -- they're pretty standard. Your guess is as good as mine whether this will be done in the future.

You can use the Symbian interfaces from Qt, but it takes a little bit of work figuring out the translations.

Is there somewhere some tutorial or example on how to use Symbian libraries from Qt?
