[dxcode] A distinctive, URL‑safe binary encoder with the signature `dx` prefix and CRC16 checksum.

Project description

dxcode - Python 实现

带有 dx 前缀的自定义编码算法的 Python 实现。

安装

pip install dxcode

或从源码安装:

git clone https://github.com/dogxiii/dxcode.git
cd dxcode/implementations/python
pip install -e .

使用方法

基本使用

from dxcode import dx_encode, dx_decode, is_dx_encoded

# 编码字符串
encoded = dx_encode('你好,Dogxi!')
print(encoded)  # dxXXXX...

# 解码
decoded = dx_decode(encoded)
print(decoded)  # 你好,Dogxi!

# 检查是否为 DX 编码
print(is_dx_encoded(encoded))  # True
print(is_dx_encoded('hello'))   # False

编码字节数据

from dxcode import dx_encode, dx_decode

# 编码字节
data = b'\x00\x01\x02\xfe\xff'
encoded = dx_encode(data)
print(encoded)

# 解码为字节
decoded = dx_decode(encoded, as_bytes=True)
print(decoded)  # b'\x00\x01\x02\xfe\xff'

处理文件

from dxcode import dx_encode, dx_decode

# 编码文件内容
with open('secret.txt', 'rb') as f:
    encoded = dx_encode(f.read())

# 保存编码后的内容
with open('secret.dx', 'w') as f:
    f.write(encoded)

# 解码文件
with open('secret.dx', 'r') as f:
    decoded = dx_decode(f.read(), as_bytes=True)

with open('secret_decoded.txt', 'wb') as f:
    f.write(decoded)

API 参考

dx_encode(data)

将数据编码为 DX 格式。

参数:

  • data: str | bytes | bytearray - 要编码的数据

返回值:

  • str - 以 dx 为前缀的编码字符串

示例:

dx_encode('Hello')      # 字符串
dx_encode(b'\x00\x01')  # 字节

dx_decode(encoded, as_bytes=False)

将 DX 编码的字符串解码。

参数:

  • encoded: str - DX 编码的字符串(必须以 dx 开头)
  • as_bytes: bool - 是否返回字节(默认 False,返回字符串)

返回值:

  • str | bytes - 解码后的数据

异常:

  • ValueError - 如果输入不是有效的 DX 编码

示例:

dx_decode('dxXXXX...')                    # 返回字符串
dx_decode('dxXXXX...', as_bytes=True)     # 返回字节

is_dx_encoded(s)

检查字符串是否为有效的 DX 编码。

参数:

  • s: str - 要检查的字符串

返回值:

  • bool - 是否为有效的 DX 编码

get_dx_info()

获取 DX 编码的信息。

返回值:

  • dict - 包含版本、作者、字符集等信息

常量

from dxcode import DX_CHARSET, DX_PREFIX, DX_MAGIC, DX_PADDING

print(DX_CHARSET)  # DX 字符集
print(DX_PREFIX)   # 'dx'
print(DX_MAGIC)    # 0x44
print(DX_PADDING)  # '='

命令行工具

安装后可以在命令行使用:

# 编码
echo "Hello, Dogxi!" | dx-encode

# 解码
echo "dxXXXX..." | dx-decode

# 或者直接使用
dx-encode "Hello, World!"
dx-decode "dxXXXX..."

异常处理

from dxcode import dx_decode, DxEncodingError

try:
    dx_decode('invalid-string')
except DxEncodingError as e:
    print(f'解码错误: {e}')
