Net err_cert_weak_signature_algorithm sửa lỗi năm 2024
A weak signature algorithm error is triggered by an SSL issue on the server and can only be fixed by the website owner or managerIf you’re here it’s probably because you’ve received a NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM error while using Google Chrome to visit a website. Unfortunately, this “your connection is not private” error is not something that a user can fix, the problem is the website’s SSL certificate. Show
ERR_CERT_WEAK_SIGNATURE_ALGORITHM is a relatively uncommon errorWhile not all that common, the issue is that the SSL certificate in question was issued with an outmoded signature algorithm. A signature algorithm is a portion of what is called a cipher suite, which is essentially a group of algorithms that perform the encryption functions needed to secure a connection. In this case the SSL certificate was likely issued with the SHA-1 algorithm, which was deprecated in 2015. Until the site owner re-issues their SSL certificate with a support signature algorithm, you shouldn’t use the site. (Basically, the site is using security technology that can be easily compromised by hackers.) How site owners can fix NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHMThis is a simple fix, you’re going to need to re-issue your SSL certificate with the SHA-2 or SHA-256 hashing algorithm. Most CAs and SSL services give you the option to select while you’re ordering your certificate. If it’s easier, you can just purchase a new SSL certificate that will automatically be issued with the SHA-256 hashing algorithm. Any SSL certificate purchased from our website is automatically issued with the latest algorithms and will fix a ERR_CERT_WEAK_SIGNATURE_ALGORITHM error message. Save Up 75% On Comodo SSL CertificatesTip: You can typically save a significant amount by buying your SSL certificate direct instead of through your web hosting company. We sell all Comodo SSL certificates at up to 75% off. Compare SSL Certificates If your certificate was purchased from us previously, simply access your control panel, choose to re-issue your SSL certificate. (We disabled SHA-1 a long time ago). In this tutorial, we’ll show you how to fix the NET:: ERR_CERT_WEAK_SIGNATURE_ALGORITHM error – a rare but critical SSL connection error that could jeopardize users’ security if browsers turned a blind eye to it. Thankfully, the likes of Chrome and Firefox block website access immediately and leave you with this error message on your screen. What causes the NET:: ERR_CERT_WEAK_SIGNATURE_ALGORITHM errorAs this is a server-side error, the most probable cause is, as the name implies, a weak signature algorithm, specifically, the SHA-1 signature hashing algorithm. Even if it’s been phased out by all the major browsers, old servers, and systems that aren’t regularly maintained and updated may still support it, posing a security risk to visitors. How to Fix the NET:: ERR_CERT_WEAK_SIGNATURE_ALGORITHM Error if You Are a Website OwnerHackers can exploit the weaker protocols and intercept sensitive data in transit between users’ browsers and the website’s server. That’s why, if you see this error on your website, you should rectify it as soon as possible. Nowadays, all SSL certificates follow the latest cryptographic protocols and security standards, so the certificate itself isn’t the issue. The current SSL validity is set to just one year, but even if your SSL cert was three years old, it still wouldn’t support the outdated SHA-1 algorithm. The problem is on the server-side, and the solution is to either configure your server or move to a new hosting account. If your SSL certificate is issued by a commercial Certificate Authority and is still valid, you don’t need to buy another one, as all paid certs come with unlimited server licensing. How to Fix the NET:: ERR_CERT_WEAK_SIGNATURE_ALGORITHM Error if You Are a Website VisitorIf the NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM error occurs just on your network, but the website loads fine from another location or device, we have a couple of quick fixes for you that will eradicate the error in no time. Try one of our solutions below, and see which one works for you. 1. Adjust the Date and TimeWhen the date and time on your device are out of sync with the date and time on your server, Chrome and other browsers will display all sorts of connection errors, including the very one we’re discussing in this article. You can correct the date and time with just a few clicks on your Windows PC:
If you’re using Mac:
2. Clear the SSL SlateTo save time from checking your digital certificate every time during a connection, the SSL slate stores a cache of SSL certificates on your device, and you can empty it just like you would clear your browser’s cache. Follow the steps below: On windows:
On Mac: To clear the SSL slate on Mac, you just need to clear your browser’s cache. By clearing your browser’s cache you can also get rid of this problem on a Windows machine. 3. Clear your browser’s cacheIt’s never a bad idea to clear your browsing data from time to time, just to keep things tidy and avoid the off-putting SSL connection errors. You may even get rid of the NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM error in the process.
4. Reset your network settingsSometimes, the problem may come from your network settings. A quick fix is to reset them to the default value. Please note, you’ll need an administrator account to perform this task:
5. Updated your BrowserAn old browser may still support the now-deprecated SHA-1 algorithm, so if you haven’t updated your system or browser for a good while, now it’s the perfect time to do it. Here’s how you can update Chrome, but the process is similar to other browsers.
6. Check your antivirus and firewall settingsYour antivirus protects you around the clock, but sometimes it may interfere where it shouldn’t. Ensure that the website you’re trying to access isn’t blocked by the firewall or other filters. You may need to disable the antivirus to see if it causes the error, but make sure to enable it back after you troubleshoot the issue. Bottom LineWe’ve exhausted our list of potential solutions for the NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM error. Hopefully, you’ve found a fix by now. If the issue is on the server-side, upgrade your server configuration or get a new hosting account. If you can’t access the website as a user, try one of our quick fixes.
