What is an RSA file?
File that contains an RSA digital certificate; used in public-key cryptography and enables a remote entity to be authenticated; may be used by a software program for secure communication with a remote server.
Examples of software programs that use RSA files include Mozilla Firefox and Adobe Photoshop Elements. Firefox uses them so that developers can digitally sign browser extensions (.XPI files).

The CODESIGN.RSA file is also saved with CODESIGN.SF file. Neither file should be tampered with or the game may not run properly. CODESIGN.RSA was previously named MOJANG_C.DSA.
NOTE: The META-INF directory is a standard convention used by JAR files to store metadata for the archive.
