Hand-Written Core Socialist Values Encoding Tool - Python Implementation

Preface

Today is May Day, Labor Day. Happy holiday to all proletarian workers!

Then let's have some fun and share something interesting~

This little tool is something I made for fun in college. For all you successors, the 12-word Core Socialist Values are something everyone is very familiar with. This tool can encode a piece of text into Core Socialist Values for encryption, and can also decrypt the ciphertext.

Why did I make this? It's been too long, I don't quite remember, seems like it was because trash-talking teammates in games kept getting censored, so I had a flash of inspiration: if I replaced it with harmonious text, it wouldn't get censored, right (jk

Implementation Principle

Briefly explaining the principle—it's quite simple. Our text is represented as ASCII in computers. To a computer, all data is 0s and 1s, i.e. binary. The "Core Socialist Values" we're familiar with have 12 words, and each word can represent one digit, so we can define a new encoding: a base-12 encoding made of "values"~

We just need to convert binary ASCII characters into base-12 "values" encoding.

Let's Start Coding

Once the principle is clear, we can start writing code. This article uses Python to implement it (I may try implementations in other languages later)

Here we use Python's standard library binascii to handle ASCII encoding. First, import it.

Converting ASCII to binary can be done with the binascii standard library; converting to base-12 we'll have to implement ourselves.

(At the time) considering that converting binary directly to base-12 is rather troublesome, I compromised: first convert binary to decimal, then convert to base-12.

The code for converting decimal to base-12 is as follows

def from_num(input_num: int, b: int) -> int:
    """
    将数字转换为指定进制
    :param input_num: 输入的数字
    :param b: 进制
    :return: 输出结果
    """
    return ((input_num == 0) and "0") or \
           (from_num(input_num // b, b).lstrip("0") + "0123456789abcdefghijklmnopqrstuvwxyz"[input_num % b])

With the prerequisites in place, let's start writing the encryption code

def encode(raw: str) -> str:
    """
    编码
    :param raw: 输入的原始字符串
    :return: 返回编码结果
    """
    result = list()
    for char in raw:
        # 把字符转换为16进制字符串
        str_16 = binascii.b2a_hex(char.encode('utf-8'))
        # 把16进制字符串转换为10进制数字
        num_10 = int(str_16, 16)
        str_12 = str(from_num(num_10, 12))
        result.append(char_replace(str_12))

    return ','.join(result)

The code is very simple; everything is clearly written in the comments.

Then comes decryption—just reverse the encryption process.

def decode(encoded: str) -> str:
    """
    解码
    :param encoded: 已编码字符串
    :return: 解码的原始字符串
    """
    str_list = encoded.split(',')
    result = list()
    for char_list in str_list:
        # 整个12进制字符串
        char_12 = ''
        for char in char_list.split(' '):
            # 还原出12进制字符串
            str_12 = str(total_list.index(char))
            if str_12 == '10':
                str_12 = 'a'
            if str_12 == '11':
                str_12 = 'b'
            char_12 += str_12
        # 12进制串转换为10进制数
        num_10 = int(char_12, 12)
        str_16 = hex(num_10)

        result.append(binascii.a2b_hex(str_16[2:]).decode('utf-8'))
    return ''.join(result)

Testing the Results

The code is done, let's test how well it works

print(encode('劳动节快乐'))

Result

平等 富强 平等 平等 法治 富强 和谐,平等 富强 平等 平等 公正 友善 自由,平等 民主 文明 友善 自由 富强 文明,平等 富强 公正 民主 平等 文明 和谐,平等 富强 文明 诚信 法治 文明 爱国

A bit long, hahaha, but it's fine for fun

Let's try decrypting

print(decode('平等 富强 平等 平等 法治 富强 和谐,平等 富强 平等 平等 公正 友善 自由,平等 民主 文明 友善 自由 富强 文明,平等 富强 公正 民主 平等 文明 和谐,平等 富强 文明 诚信 法治 文明 爱国'))

We can correctly get the original text

劳动节快乐

Online Demo

I quickly put together a page. If you're interested, feel free to play around with it: http://dc.sblt.deali.cn:9800/core-socialist-values/

PS: Even better if you post the encrypted result in the comments
