A jar package for null

• Made for fun

• As they added file SHA-256 check, we have to patch the main jar
• Use jadx and other tools to locate the CEAppDef file (in 4.2.0.1 it's g.class)
• modify the checksum (using 010 editor or other tool, original checksum is 6b80a0f06acb44524d65d72edf4a097062f41edab54a53063f926d553f9647fa)
• Remove the .RSA .SF and MANIFEST.MF file in META-INF
• Move back the main jar and the rlm1221.jar
• Done~ just enjoy!

• As they added the SHA-256 check, we can also change the .bat file
• Modify the CLASS_PATH, rename the app\lib\rlm1221.jar to rlm1221_mod
• Also modify your jar file to rlm1221_mod.jar and copy that into app\lib
• Change all 4 .bat files and you are ready to go
• LOL

• Plz get SHA-256 and convert to lower-case, and follow the instruction
