Description

Minecraft 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.

  1. Edit config/minecrafttls-common.toml and set alwaysDisableVanillaEncryption to true.
  2. 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:
