Javaedit - Detection via Hash/Content

Javaedit refers to a category of cheats where the core Minecraft vanilla .jar file itself (not a mod) has been directly modified at the bytecode level to incorporate cheats, such as enhanced reach, modified knockback physics, or altered hit detection. These often masquerade as standard vanilla versions within the versions folder.

• Primary Detection Method (Hash Comparison): The most reliable and definitive method for detecting Javaedit is identical in principle to the mod hash check.

  1. Identify the exact vanilla Minecraft version the player claims to be using (e.g., 1.8.9, 1.16.5).

  2. Locate the corresponding core game .jar file within the player's active .minecraft/versions/{version_name}/ directory (e.g., 1.8.9.jar).

  3. Calculate the SHA256 hash of the player's .jar file.

  4. Obtain the official SHA256 hash for the exact same vanilla Minecraft version from a trusted source (e.g., official Minecraft resources, reputable community wikis like the Minecraft Wiki on Fandom/Wiki.gg which often list official hashes).

  5. Compare the hashes.

• Verification: Any discrepancy whatsoever between the hash of the player's .jar file and the official hash for that specific vanilla version constitutes absolute proof that the file has been tampered with and is not a legitimate, unmodified vanilla client. This is a direct bannable offense on virtually all servers. Again, ensure you are comparing against the hash of the exact version number.
