mTLS
Java mod listed for Minecraft 26.x. Downloads from the MC Java Mods app on Android.
⬇ Download on ModrinthMinecraft TLS (mTLS)
Adds Mutual TLS (mTLS) support to Minecraft. Encrypts traffic and acts as a strict player allowlist using certificates - only players with a valid client certificate can connect.
Made so friends don't need to install external tools like
stunnel.
🛠️ Server Setup
Place your certificates in config/mtls_server/:
ca.crt(CA certificate)server.crt(Server certificate)server.key(Server private key, PKCS#8 format)
Using an Nginx SSL Reverse Proxy? You still need this mod on the server to disable vanilla Minecraft encryption.
- Edit
config/minecrafttls-common.tomland setalwaysDisableVanillaEncryptiontotrue.- Do not place certificates in
config/mtls_server/(this disables the mod's native TLS so Nginx can handle it).
🖥️ Client Setup
Configure mTLS settings directly in the server edit screen:
