libcode

a general encoder/decoder for Chinese obfuscation

inspired by https://sym233.github.io/core-values-encoder/

how to use

• please see app/icved/icved.go

encode:

• 2500 common used Chinese character: map to 1-2500, map to 9 based number list with prefix 11
• unicode Chinese character: map to [1, unicode Chinese code block size], map to 9 based number list with prefix 10
• other words: map to [1, unicode code point], map to 9 based number list with prefix 9
• 9 based number list with prefix map to 12 core value word.

decode:

• core value word, map to 9 based number list, check prefix to transform number list with:
• prefix 11: map to [1, 2500], map to one of the 2500 common used Chinese characters
• prefix 10: map to [1, unicode Chinese code block size], map to unicode Chinese character
• prefix 9: map to unicode code point, map to unicode character
