    Data file encryption in S60 3rd

    I have a large txt file together with the application. I want to encrypt the data file firstly and copy it to the phone. On the phone end, the application will decrypt the data file and read the content in it.

    Does anybody know the class and api in symbian 9.1 that can encryption the data file? (I use S60 3rd.)

    So you mean I should use third party encryption algorithm to encrypt a data file?
    I searched in the forum, there are some class concerning encryption in s60 2.x. I am wonderring if they have been removed in s60 3rd.

    if you know the APIs you want to use, you could always check if they have headers present in the SDK, also SDK help might have documentation of them, so quite easy to figure it out.

    Acctually, it is not that easy.
    All the previous api for encryption that I can find like CSecurityEncryptBase can not be found in s60 3rd.

    And I could not an example for such applications.

    basically I meant that its easy to find out if they are still there, and I quess they are not. So then you might want to look using other implementations, here's link to one: http://www.newlc.com/AES-Encryption.html
