问题 I have a code that constructs an RSA public key on MacOS with the help of the security framework. This works fine on 10.11/10.12/10.13, but today I found that this fails on 10.9. Below is the constructor of the class that wraps the key: CRSAPublicKey(const unsigned char* pExponent, const std::size_t nExponentSize, const unsigned char* pModulus, const std::size_t nModulusSize) { static const SecAsn1Template kRsaPublicKeyTemplate[] = { { SEC_ASN1_SEQUENCE, 0, NULL, sizeof(ASN1_RSA_PUBLIC_KEY) }

问题 I am developing an iOS app using swift 3. I need to export an SecKey (which is the user RSA publickey reference) to a string (e.g base64) in order to share it through a generated QRCode. It also has to work the other way since the other user that scans the QRCode , will be able to rebuild a SecKey reference from the string extracted from the QRCode. I found few tutorials but I don't understand exactly what I need to extract from the SecKey reference, and I don't know how to convert it to a
