SSL server probably obsolete error with Chrome

Problem: Chrome and Firefox recently updated and suddenly stopped allowing connections to your SMP3 Admin and possibly your applications and is giving you the error Server has a weak ephemeral Diffie-Hellman public keyThis is an attempt by the browsers to protect you from connecting to a Server that is using outdated cipher settings which could lead to a recently published SSL vulnerability "logjam".The ciphers being used by SMP3 SP08 and prior server versions are defaulting to obsolete choices. I believe this is being updated for the SMP3 SP09 release. However, in the meantime you can make a similar change to your server to update the ciphers using the following procedure.The quickest fix is to just remove the TLS_DHE_RSA_WITH_AES_128_CBC_SHA from the default cihpers list. This removes the one google is complaining about. You can also just update the ciphers as indicated below to add support for some of the newer cihphers. This won't hurt anything but I also don't know which ones are actually used or support by the browsers.Solution:Stop the SMP3 serverEdit the Server\confg_master\org.eclipse.gemini.web.tomcat\default-server.xml fileFind the ciphers line in each of the following Connector tags and replace the value with the ciphers below.Connector smpConnectorName="oneWaySSL"Connector smpConnectorName="AdminSSL"Connector smpConnectorName="mutualSSL"ciphers="TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA256,TLS_RSA_WITH_AES_256_CBC_SHA"Save and restart the SMP3 server. Now connections from Chrome and Firefox should no longer give that error.The key is to remove the TLS_DHE_* ciphers. This list contains probably more options that you will need but I leave it to you to determine which ones you want to support.For Agentry clients be sure to test each device you will be using BEFORE making this change in production. If your device does not support the newer ciphers it will probably fail to connect and you may need to either update your device or re-implement the obsolete cipher.

Travel, or for those who don’t have access to a reliable internet connection. How does a VPN work? So how does a VPN protect you? Let's look under the hood and see how things work. Protocol name Encryption Routing Use Case OpenVPN 256-bit AES encryption using OpenSSL TCP and UDP, SSL/TSL Best overall use SSTP 256-bit AES encryption TCP, SSL/TSL Best option for Windows IKEv2 / IPSec 256-bit AES encryption UDP Best option for mobile browsing L2TP / IPSec 256-bit AES encryption UDP Best option for basic setup PPTP 128-bit encryption TCP None; obsolete WireGuard 256-bit AES encryption UDP Best option for early adopters When an attempted connection is made to the VPN provider's remote server, the server authenticates the user and creates an encrypted tunnel for their data to run through. The data that funnels through this tunnel gets scrambled into code and rendered illegible by anyone who does not have access to the encryption key, and therefore does not have permission to read it. Once this data reaches the server, the server uses its own private key to decrypt the data and make it readable. The server sends the decrypted data, along with a new IP address, back to the site you’re attempting to connect with. How this encryption process occurs—and whether it's fully secure—depends on the type of protocol, or system of instructions, used to make the connection. A VPN service can only guarantee security and peace of mind when backed by a strong protocol. It's the

For the futureIf current technological processing development follows Moore's Law or the leap to quantum computing is made at a large scale, many cryptographic algorithms and best practices will be overcome and made obsolete. This will expose anything the encryption is protecting and could put legacy data in danger. Many experts have raised concerns that individuals and nations around the world are collecting data with the goal in mind of decrypting it at a later date when the processing makes it trivial.PFS prevents this strategy as an option altogether. It does not transmit any of its session keys over the network, instead, PFS uses symmetric encryption methods that generate session keys independently through complex authentication equations performed by both sides.Another option to help prevent this issue is the utilization of quantum cryptography, a developing field. How to achieve perfect forward secrecyEnabling PFS support on a server is simple, and most modern servers are already configured for it. If not, you can generally do so in four straightforward steps:Go to the SSL protocol configurationAdd the SSL protocolsSet an SSL cipher that’s compatible with PFSRestart your serverPerfect forward secrecy can be accomplished on most web servers including Apache, Nginx, RSA, and others.

Berlaku SSL/TLS dan perlu tidaknya diperbarui.Berikut contoh laporan SSL untuk website Hosteko yang dibuat menggunakan tool SSL Labs :2. Mengaktifkan dukungan TLS 1.3Sebagai lapisan keamanan terbaru dari teknologi SSL, TSL (Transport Layer Security) membuat koneksi yang aman antara browser dan server web. Jika fitur ini dimatikan, browser akan menolak sertifikat dari beberapa website. Inilah yang kemudian menyebabkan munculnya sejumlah masalah.Untungnya, sebagian besar browser modern, seperti Google Chrome, sudah dilengkapi dengan TLS 1.3 secara default.Hanya saja, jika Chrome yang dimiliki masih versi lama, Anda harus mengikuti langkah berikut untuk mengaktifkan dukungan TLS browser :Buka Google ChromeKetika chrome://flags di kolom URL Chrome, lalu tekan EnterCari TLSAktifkan (Enable) dukungan TLS 1.3Sayangnya, opsi ini tidak tersedia di versi baru Google Chrome.Misalnya, jika Anda menerapkan keempat langkah di atas di Chrome versi 80.0.3987.1222, opsi yang didapat hanyalah TLS 1.3 downgrade hardening. Fungsinya untuk “memperkuat” koneksi TLS 1.3 dan memperbolehkan downgrade di versi TLS yang lebih lama (atur ke default).3. Menonaktifkan protokol QUICProtokol QUIC (Quick UDP Internet Connections) adalah proyek eksperimen Google yang bisa mengirim package sederhana menggunakan User Datagram protocol (UDP) tanpa memerlukan koneksi.Meskipun QUIC dikenal sebagai alternatif terbaik dari layanan keamanan lain, seperti TCP, HTTP/2, dan TLS/SSL, protokol ini terkadang memicu peringatan konten campuran, termasuk ERR_SSL_VERSION_OR_CIPHER_MISMATCH.Oleh karena itu, Anda harus mematikannya untuk mengatasi masalah koneksi sertifikat SSL. Berikut langkah-langkahnya (via Google Chrome) :Buka Chrome dan ketik chrome://flags di kolom URL, lalu tekan Enter.Anda akan diarahkan ke halaman fitur experimental. Cari QUIC.Atur Experimental QUIC Protocol ke opsi Disable.Selesai!Cara lain untuk mematikan protokol QUIC adalah dengan menggunakan Application Control atau Firewall Policy. Namun, karena penggunaan kedua metode ini menuntut Anda untuk paham hal-hal teknis, kami tidak merekomendasikannya.4. Menghapus web history/cacheWeb history dan web cache akan menyimpan data situs yang diakses melalui browser. Data ini bisa berupa teks, gambar, atau file. Mengaktifkan cache berarti mempercepat akses buka halaman web.Sayangnya, data yang tersimpan cenderung data statis dan lama. Apalagi kalau situs sudah melakukan beberapa perubahan, data yang ada tidak sesuai. Cache yang tak kunjung dihapus dapat mengakibatkan error pada SSL dan risiko keamanan jangka panjang.Menghapus cache di perangkat dan memulai kembali browser akan jadi solusi terbaik untuk mengatasi ERR_SSL_VERSION_OR_CIPHER_MISMATCH.Apabila cara ini tidak juga menghilangkan error, bersihkan SSL State di browser.Berikut langkah-langkahnya (untuk Google Chrome versi 80.0.3987.122) :Arahkan kursor ke sudut kanan layar atas Chrome, klik 3 tanda titik, dan pilih Settings.Scroll ke bawah ke area Settings dan cari lalu klik opsi Advanced.Klik Open Proxy Settings.

ORA- : SSL transport detected invalid or obsolete server

Quick Tips Google Chrome typically displays the “Your connection is not private” error when it fails to establish a secure connection or cannot verify the authenticity of the Secure Sockets Layer (SSL) certificate.Problems with your internet connection, browser extensions, or antivirus programs can also cause this error.While you can configure Google Chrome to ignore these SSL connection errors entirely, doing so can be risky. Try Basic FixesSwitch to a different network: If you use a public Wi-Fi connection at a restaurant, mall, or airport that runs on the HTTP protocol instead of HTTPS, Chrome might interrupt you with a “Your connection is not private” error. Consider switching to a private network and loading the webpage again.Disable VPN: Using a VPN connection can sometimes make it complicated for Chrome to verify the SSL certificate, leading to connection errors. Try turning off your VPN temporarily to see if that resolves the error.Fix 1: Correct Date and Time on Your PCIf your PC shows an incorrect date or time, it can prevent apps and browsers from connecting to a server. Since SSL Certificates are only valid for a specific period, setting your PC to the correct date and time is essential to establish a secure connection.On WindowsStep 1: Press the Windows key + I to open Settings. Navigate to Time & language > Date & time.Step 2: Turn on the toggle for Set time automatically.On MacStep 1: Click the time indicator in the menu bar and select Open Date & Time Preferences.Step 2: Under Date & Time, check the box for Set date and time automatically. Then, use the drop-down menu to select the preferred time server.Fix 2: Clear Cache and CookiesIf you face the error despite switching networks and verifying the clock on your PC, Chrome may be loading a cached version of the web page. To ensure that Chrome is fetching a fresh copy of web pages, clear the existing cache and cookies.To do so, press Ctrl + Shift + Delete to launch the Clear browsing data panel. Select All time in the Time range section and check the boxes for Cookies and other site data and Cached images and files. Then, hit Clear data.Fix 3: Disable Antivirus ProgramLike Chrome, antivirus programs on your PC also actively scan for the website’s SSL certificate. You can dig through the settings of your antivirus program to disable HTTPS scanning or turn off the antivirus program momentarily to bypass certificate errors in Chrome.Fix 4: Turn off Browser ExtensionsThere’s a chance that one of your third-party extensions is acting up and preventing Chrome from establishing a secure connection. If you suspect that, try turning off all the extensions and see if it helps.In Chrome, type chrome://extensions in the URL bar and hit Enter. Then, use the toggles to disable all your extensions one by one.Restart the browser after this and see if the error occurs again.Fix 5: Change DNS SettingsAnother fix that worked for many users to resolve the “Your connection is not private” error

They do appear.Google also tested and designed warning messages to manipulate user actions in the desired direction and made it more difficult for users to ignore the warning.The study and changes in Chrome flipped the data. After Google implemented the changes, 68 percent of Chrome users receiving an SSL related warning reversed their course.What do the changes in Chrome mean for your business?The changes in Chrome mean that 68 percent of users head straight to the competition when they encounter an SSL related warning. Let’s say your site receives 500,000 users a day. An expired certificate may cost you 350,000 users in a 24-hour period. If your users only saw the error for two hours, you’ve lost over 40 thousand users on average during those two hours. That’s a lot of potential conversions lost.SSL certificate warnings won’t happen on my siteSure they will. At some point, a flaw in your planning will allow a certificate to fail; it happens all the time to even the biggest sites. For example, Microsoft Teams’ certificate expired a few months ago. Microsoft notified users on Twitter.We’ve determined that an authentication certificate has expired causing, users to have issues using the service. We’re developing a fix to apply a new certificate to the service which will remediate impact.

However, you can mitigate SSL certificate related problems with a proactive approach to SSL certificate maintenance. First, let’s review some common SSL certificate errors.6 causes of SSL certificate related errorsGoogle’s article, Where the Wild Warnings Are: Root Causes of Chrome HTTPS Certificate Errors, details the findings of a several month study to find out the common reasons for SSL certificate warnings. The following is an overview of the issues they found. For detailed descriptions, please see the article.Expired certificates otherwise known as server date errors. A certificate has an effective date range with a start and end date. If the current date falls outside the date range, the browser issues an invalid.

Get Unused Stored Procedures from Sql Server 2008 While working in projects, I always used to wonder about maintaining Stored Procedures in Sql Server. The way in which we organize them is that we go on adding the required stored procedures with some name convention so that we can identify what is the module to which this SP refers. But as the project goes ahead modifications come, we go on adding required Stored Procedures and some Stored Procedures become obsolete because of business rule changes. But as far as I have observed in IT projects, these stored procedures are kept as it is and when the project completes no one has any idea about which Stored Procedures are currently in use and which are obsolete. But I have come across this post, which shows how to get probably unused SPs from Sql Server 2008. The query is as follows, which returns SPs which are not in procedure cache. //The first part gives list of all SPs and also works in SQL2005 Select p.name From sys.procedures as p where p.is_ms_shipped =0 except //The second part works only in SQL 2008 select p.name from sys.procedures as p inner join sys.dm_exec_procedure_stats as q on p.object_id = q.object_id and is_ms_shipped=0 This combine SP gives you probably unused SPs from Database.
