A calculate program that can make "exclusive or" operation byte by byte for the input file. Interesting and fortunately, the program can "exactly" decode the cache of NetEase Music.
The program read a byte and xor 0xA3 , then write the answer to output file immediately.
(Why 0xA3? See the reference)
Drag the file on the exe (e.g. .uc file in "...\Cache"), the program will output the file at where input file is. You may manual change the extension to ".flac" instead of ".mp3" at certain times.
