Hello,I am currently creating a framework to able communication with JWT(JSON Web Token) on iOS, and I would like to convert the key that I get from that token, convert it into PKCS#1 since I saw that the SecKey save the rsa key in this format.My question is, is it possible to add some additional attributes (string/data) on the SecKey variable with SecKeyCreateWithData() ? I got SecKey data in return of this function, but didnt get the extra attributes data that I attached on the label.I tried to add some additional information for my json token, and add it into the kSecAttrLabel and kSecAttrApplicationLabel, and with the SecKeyCopyAttributes, I got nil for the kSecAttrLabel , kSecAttrApplicationLabel returned totally different data.Many thanks in advance! 🙂
