Windows XP lacked any modern cipher support in his heyday. With the POSReady 2009 trick you can get AES 256-Bit, TLS 1.2 support. I will show how to get them. First make sure you have the POSReady trick so you would be able to install them, next download the following updates in order:
AES 256-Bit support(KB3081320)
Update for WES09 and POSReady 2009(KB4019276)
Cumulative Update for Internet Explorer 8(KB4316682)
Update for WinHTTP to add TLS 1.2 support(KB4467770)
Install them all in order, then apply the registry file to enable TLS 1.2 and reboot. Now you can check at the Internet Options and you will see TLS 1.2 and TLS 1.1 in the list.
And Internet Explorer 8 will show that the cipher strength is now 256-Bit.
And howsmyssl.com reports that we do indeed have TLS 1.2 support and no insecure ciphers and we’re no longer vulnerable to the BEAST Vulnerability that affected TLS 1.0.
This doesn’t fully fix the issue with Chromium browsers that use XP’s schannel.dll because SNI or ECC support is not available on XP and you can get ERR_SSL_VERSION_OR_CIPHER_MISMATCH sometimes.
Since Java 8 Update 161/162 they broke the installers to prevent it to install on XP x86 (x64 is not affected) Well, I found a great solution for this problem to be solved!
If you don’t have Java already installed on your machine Download it. Please ignore this when installing it:
After you finished installing it download and extract it. Navigate to C:\Program Files\Java and we will have jre1.8.0_152 in there.
Go to your extracted jre1.8.0_212 folder and copy everything what is in it to the jre1.8.0_152 folder and confirming to override everything. After you’ve done it you can check if Java is working in “About Java”
NOTE: Java updates DO NOT work on XP since they broke it in Java 8 Update 161/162 and never fixed it! I will try my best to update the download links of this post when a new Java update is available.
On May 14, 2019 Microsoft released one new security update for XP/Server 2003 to patch”a critical remote code execution vulnerability”KB4500331 It’s the first ever official update for them(without any tweaks/tricks) since 2017! This is like Wanna-cry but without any damage yet! You can read more about it. From the article:
Given the potential impact to customers and their businesses, we made the decision to make security updates available for platforms that are no longer in mainstream support (see download links in the following table). These updates are available from the Microsoft Update Catalog only. We recommend that customers running one of these operating systems download and install the update as soon as possible
So yeah, one more update to the XP update basket.
