NSString RSA Encryption in iOS

I'm completly lost on this subjet.

I've been checking countless websites, took libraries and exemple on internet but couldn't figure what's wrong.

My issue is the following: I got a public key in rsa looking like: "MIGfMA0G......DAQAB" (you can add = at the end if you want)

And I need to encrypt a simple NSString with it. Took me 10 minutes to do so on Android but I can't figure how to make it work on iOS...

I've tried, read and tried tweaking the following:

Using the last one I manager to store something with SecItemAdd but never manager to get anything back with SecItemCopyMatching. (event though I got no error coming from SecItemCopyMatching)

Using XRSA it seems my public key is not in the right format (he advises NSString *publicKey = @"MIICs ... kT0=\n"; // Base64 encoded key and I can't get a certificate in the init with mine) but I can't change the one I have.

I'm confused and really lost. What is exactly required for such a simple thing as encrypting a string with a public rsa key that is also a string? What step are needed and can you point me out a way to do it please?
