LetsEncryptCraft

by CreeperHost

LetsEncryptCraft installs Let's Encrypt root certificates into Java at runtime, so mods can reach sites that use them on Forge 1.12.2.

ForgeClient or server, optionalMIT LicenseOpen source1.7.2 – 1.12.2

What it does

When the mod is loaded, it installs the Let's Encrypt certificate into the Java runtime. Many Java versions bundled with the launcher do not trust Let's Encrypt certificates, so connections to sites secured with them can fail. A mod author can use it to reach their own update checks or other web resources without changing the player's Java. Only the Forge loader is covered, and the files target 1.7.2 – 1.12.2. The mod is open source under the MIT License and can run on a client alone, a server alone or both.

Key features

  1. Runtime certificate install

    The Let's Encrypt certificate is added to Java when the mod loads, with no manual keystore step.

  2. Older Java support

    It covers Java builds that do not support Let's Encrypt certificates, such as those shipped with the Mojang launcher.

  3. Source available

    Source code and an issue tracker are public, and the code is open source under the MIT License.

Questions

Does LetsEncryptCraft need to be installed on servers?

Which Java versions does LetsEncryptCraft fix?

It targets Java builds that do not support Let's Encrypt certificates, which the mod detects and handles at runtime.

What the author says

You probably don't. However, if you're a modder who uses their own site and has an update check, or other kind of access to your web site, you may have come across a problem - you can't access Let's Encrypt resources on the version of Java that Mojang ship with their launcher.
