AppSync最近好奇看了一下，很简单的原理：

MISCopySignerCertificateData

MISValidateSignatureAndCopyInfo

    MISCopySignerCertificateData = reinterpret_cast(dlsym(handle, "MISCopySignerCertificateData"));
    if (MISCopySignerCertificateData == NULL)
        return;

    MISValidateSignatureAndCopyInfo = reinterpret_cast(dlsym(handle, "MISValidateSignatureAndCopyInfo"));
    if (MISValidateSignatureAndCopyInfo == NULL)
        return;

    kMISValidationInfoSignerCertificate = reinterpret_cast(dlsym(handle, "kMISValidationInfoSignerCertificate"));
    if (kMISValidationInfoSignerCertificate == NULL)
        return;
