ab.keys.crypto加密导致Python高版本镜像无法调用

Traceback (most recent call last):
    File "/usr/local/bin/abt", line 5, in <module>
    from ab.client.cli import cli
   File "/usr/local/lib/python3.8/site-packages/ab/client/cli.py", line 3, in <module>
     from ab.client.crypto_cli import crypto_impl
   File "/usr/local/lib/python3.8/site-packages/ab/client/crypto_cli.py", line 4, in <module>
     from ab.keys.crypto import ab_encryptFile
 ModuleNotFoundError: No module named 'ab.keys.crypto'

项目中ab.keys.crypto文件是经过加密后的文件，使用python3.7以上版本镜像时无法直接调用该文件，导致加密失败。
查看源码发现代码加密不需要用到ab.keys.crypto文件引用，可以注释相关内容加密代码，但数据加密仍然需要crypto内容。
另外license的验证失败了，是否与使用license.py加密时step1函数中sout = [chr(ord(a) ^ ord(b)) for (a, b) in zip(input_line, cycle("your-key"))]的“your-key”有关？由于ab.keys.crypto的加密同样无法验证
请问能否提供一份未加密的crypto.py文件？

Start by reproducing the failing abt import on a Python 3.7+ image, then read ab/client/crypto_cli.py, the ab.keys.crypto reference, and license.py's step1 function. Done means the package can load its crypto functionality and the reported encryption and license-validation failures are resolved without relying on an unavailable encrypted module.
