    You can use SSL or QCA (http://delta.affinix.com/docs/qca/).
    Actually I don't know if the latest lib is already available for Symbian.

    Hi,
    alternatively, just grab BlowFish! It is a C only algorithm, so no need to worry.

    Just check this: QSslCipher Represents an SSL cryptographic cipher

    And Also see this below link: http://doc.trolltech.com/4.6/qtnetwork.html

    According to Dan Hicks SSL library is already available on Symbian platform.

    Re: QT crypto

    Hi,
    why are you trying to focus him on SSL?

    Blowfish is really easy to get up and running, and is very very safe.

    Because SSL supports Blowfish and many other algorithms and the thread starter didn't clarify what kind of cryptography algorithms he is searching for

    Re: QT crypto

    Unfortunately, I don't think there's a way to use the cyphers in Qt's SSL module directly for encryption/decryption. I'd be interested too if someone has found a way...

    We are not talking about Qt's SSL module.

    Re: QT crypto

    Searching the forum, google and other sources I also noticed there are no libs to perform crypto on nokia QT.

    Desired functions: import certificate (X509), perform RSA encryption/decrypt, AES, (3)DES, ...

    Anyone having a -WORKING- version to do plain cryptography?
    Any idea's? (QCA doesn't compile/work, QSsl... does not allow en/decrypt, ...)

    Preferred would be that it also works in the emulator, so not only on device...

    Re: QT crypto

    There are OpenSSL and Symbian Cryptography API available out of the box. QCA should compile fine as well.

    Re: QT crypto

    With any of them you're going to have to do a little bit of work -- set up the buffers correctly, etc. Encryption is a very tricky business.
