I´m working on SMS encryption.
I´ve got S60 3rd edition SDK.
I´m using RSA algorithm provided at Symbian Criptography Library. I can encrypt and decrypt but i can´t store de keys that i generate.
First, i tried to write the KeyPair object to a file, redefining the ExternalizeL and InternalizeL methods, but these methods only work when you try to write pre-defined types (such as integer, booleans, descriptors...), and the types I want to store are CRSAPrivateKey and CRSAPublicKey.
Then I found the The unified key store, but it won´t work with my SDK (only works with S60 UIQ).
At least, i tried to write the parameters that create the keys, but It is impossible to obtain the D parameter from de Private Key.
Thank you so much.
