Hi,

No experience yet with that class but from the looks of it, it's drop in replacement for QTcpServer. So I would say that what you will have to take care of is the certificate side. Either use an official provider or if you create your own certificate, be ready to deploy them.

@Dooms said:

sslConfiguration

You don't seem to have actually associated the sslConfiguration object with the QSslSocket object.

You can set the cert/key files directly on the QSslSocket if that helps simplify your code for testing...

Please this code from me where I did exactly this:
https://github.com/cybercatalyst/qtwebserver/blob/master/tcp/tcpmultithreadedserver.cpp#L141

void MultithreadedServer::setDefaultSslConfiguration() { // Set a default SSL configuration just to have it running out of the // box. Only for development purposes, never distribute an application // that relies on SSL with the default configuration set. You can // generate your own key and self-signed certificate: // // $ openssl req -x509 -newkey rsa:2048 -keyout server.key -nodes -days 365 -out server.crt QSslConfiguration sslConfiguration; QByteArray defaultKey = "-----BEGIN PRIVATE KEY-----\n" "MIIEvgIBADANBgkqhkiG9w0BAQEFAASCBKgwggSkAgEAAoIBAQDQdRrom1g/MsJh\n" "bfwVBZH+oxuGeIBO3jeNWs2bjpDmjtEtMz66LfFVrjuggt0UeNFb1Ve3tYIVq4Wj\n" "gmHYUOB44KCzVqJrd1mZdDKukdvoalJyh5f5/kqLdNGzrfjl5fmtK4jy76xM0oV4\n" "aZlj8eC4+odrS9HLHfBylDIeSXPWtThFw02IGiQALbtW8cqHSOXhucPAwiNFELVd\n" "jjFLa0buQSWq3WSZnroLwOXxfd2dtIoDIn319wTRFPAHWQDqlIuvefYvNzel65yY\n" "ZwoomIOrcxfN7IczLxkryD1uZpr4u2aWpHpz+mB7WXhPW82H6qT205e25iDbiZUQ\n" "+2UJWBHBAgMBAAECggEBAKF7Fe066ZGLcKio2q4uMnpfP+NbVYnC+qW1wbDPL9Bq\n" "sf+hwuXW0SzeW7JrrXc+YHATRHA7WxoOVOflCIbZoAoDeHl0kz1Mp0wIh3pT41aX\n" "hmbSQxiVtIlzZT8bdcQh8tgC8YO/xml8a4hrxTd3F+4zpNOpWEtQVgNsaaasn9+h\n" "/I/8uQ6oYkNISbnrs7u2fkFAw2/RbyZ6E2Dr9fMiDVUSa5ppFFHjfkgzbGA56Mtg\n" "0DdpxWMhICVMwlTI23zmjIAssyJG6xfCQfll9XbsiPAx9/uwAMIFPaUaWBzEUmhh\n" "L+/7hESQ7DGIfKxUqtiyvT53EuupxUxkcr0useZY5UECgYEA6wis5xcEo4eBk5o4\n" "IYcdZ93LrgwKtWj6e50sVs4NgCgsDWbH99IhNIxwQnCJ02O/aacbFV0d+jB9Jh+M\n" "NKTmqDxoe+EY2WJ+sR/YZ9VZwoHFwqubL1BzroX8FBN363tjicfFA+o3bSb4OXDC\n" "PINFzSLH8cLhFOo3UFiZf9I9ZZcCgYEA4w2FDGzhnpZPToiT/nwf55Ze2lJsPWlP\n" "8XydHoIWDIbUd1LnxBnoGZF1pefexoIy8zesGBfjHC7t6tC/4zy2oqECiP6ESACN\n" "8yhSDG+iegTU59LOk+blserR52c2vNGOR7RFbAyZeg3XXwlvQOpaquIP6tc7vkv1\n" "FijDcWm3nmcCgYAUAu0Vz/PpKIRz2NGmqSZrzYqmCwhuYb3SAJPh4DFuE/2MNpAY\n" "HaAOJVb5kTNq+Dc3+65mp0MCJlbBhDYf1Vp+QIZ05bmD6Mr4sclvLc8yrHH2HT5d\n" "TPBMj8PiwbWYKy1ScdvodWy6snK4EU24cUTkLm3vu7QGX9rN0H1hULlBiQKBgQC5\n" "rgW/ao98HJoQtFqrBCEnR+6cBkmkUypgZzMqjuGvLtg0GOWWlkUcG7uliKDDoBhA\n" "lKe1MFu3YZ2JqVszXyRQjPHAzLurEmEDmFa4+tZZiPf/+YKcq3fubwVngx3dflYn\n" "x4H6YbdlfEpD2zhTUxQAqUyxFYEzF3T/wShL6FOUQwKBgA2qSGUvxHcyWw8jnQ2g\n" "BbwtU75LCvTrSuIQ8DJIVt5+W9iseNi+q51w6hTAUleJ+4X7RDrSisQucbDAY+Fg\n" "Tyz0YVk4+WR0G7ZYAjLJBe7KpzpDZ4mI8yhfYBMhH+Rtkzk96ECezEve8L3llUqD\n" "s7+8TR6cFYhHQQH3DQ5BKdt0\n" "-----END PRIVATE KEY-----"; QByteArray defaultCertificate = "-----BEGIN CERTIFICATE-----\n" "MIIDhzCCAm+gAwIBAgIJAP9LmloP2P0tMA0GCSqGSIb3DQEBCwUAMFoxCzAJBgNV\n" "BAYTAkRFMRMwEQYDVQQIDApTb21lLVN0YXRlMSAwHgYDVQQKDBdRdFdlYlNlcnZl\n" "ciBEZXZlbG9wbWVudDEUMBIGA1UEAwwLRGV2ZWxvcG1lbnQwHhcNMTUwNDIxMDYw\n" "MTE4WhcNNDUwNDEzMDYwMTE4WjBaMQswCQYDVQQGEwJERTETMBEGA1UECAwKU29t\n" "ZS1TdGF0ZTEgMB4GA1UECgwXUXRXZWJTZXJ2ZXIgRGV2ZWxvcG1lbnQxFDASBgNV\n" "BAMMC0RldmVsb3BtZW50MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA\n" "0HUa6JtYPzLCYW38FQWR/qMbhniATt43jVrNm46Q5o7RLTM+ui3xVa47oILdFHjR\n" "W9VXt7WCFauFo4Jh2FDgeOCgs1aia3dZmXQyrpHb6GpScoeX+f5Ki3TRs6345eX5\n" "rSuI8u+sTNKFeGmZY/HguPqHa0vRyx3wcpQyHklz1rU4RcNNiBokAC27VvHKh0jl\n" "4bnDwMIjRRC1XY4xS2tG7kElqt1kmZ66C8Dl8X3dnbSKAyJ99fcE0RTwB1kA6pSL\n" "r3n2Lzc3peucmGcKKJiDq3MXzeyHMy8ZK8g9bmaa+LtmlqR6c/pge1l4T1vNh+qk\n" "9tOXtuYg24mVEPtlCVgRwQIDAQABo1AwTjAdBgNVHQ4EFgQUm4DLVsXhMy8J7Us4\n" "QoTdTgVS9CEwHwYDVR0jBBgwFoAUm4DLVsXhMy8J7Us4QoTdTgVS9CEwDAYDVR0T\n" "BAUwAwEB/zANBgkqhkiG9w0BAQsFAAOCAQEAmxPOPLbq0EBBWrboNfGtD1OTnchy\n" "kBlhrSG+2gLNS3lfiphOZ+qtUGNTgewAk+nR5sraw4uFG8+6oQmNFS35zlbzWhgC\n" "dveQaT4CNtXCpAevRCbhhuDxzU0W0Dtenf3xFBC2wUWbAwxGZuklyA5ohl9+1By7\n" "YG5dPYYsgoeQl9t5yg5orh39kcrrz/exNlPH71qZO6QrPLlaRs0q4S4Yj33hgm/1\n" "XAILf9ZtcTElTRhSHC81bZz2HG84nP39WJCe4hH081cdkAMm7W2fzPTzHUWWRW34\n" "PMB0Ipp7R7CrztyxyaaDo1S3ozEpqvVT0KI65dWLt8ZsggcKxP6P5aeCBQ==\n" "-----END CERTIFICATE-----"; QSslKey sslKey(defaultKey, QSsl::Rsa); sslConfiguration.setPrivateKey(sslKey); QSslCertificate sslCertificate(defaultCertificate); sslConfiguration.setLocalCertificate(sslCertificate); sslConfiguration.setProtocol(QSsl::AnyProtocol); setSslConfiguration(sslConfiguration); }
