运行报错，“ValueError: ECC key format is not supported”。
安装了pycryptodome的3.10.1,3.10.4,3.17版本，都报相同的错误。

ValueError: ECC key format is not supported
这个应该不是pycryptodome的问题，问题应该出在socket的数据传输上。
我本地没法复现这个问题，如果你可以复现的话，可以在psi/base/sender.py的第17行插入一行代码
print(f"key {bk_bytes.hex()}")
观察程序的输出。
正常的key应该是以30开头的，长度为59的bytes（hex长度为118）。
如果不是，说明是socket数据传输的问题。
修改了代码之后，你需要pip install -e .来重新安装一下才能让修改的代码生效。
