What is an SF file?
File used by Minecraft, a 3D world construction game written in Java; saved within the Minecraft.jar file in the \META-INF\ directory of the .JAR archive and uses the name CODESIGN.SF; saves a digital signature used to verify the contents of the archive.
The CODESIGN.SF file is also saved with the file CODESIGN.RSA. Neither file should be modified or the game may not function properly. CODESIGN.SF was previously named MOJANG_C.SF.
