我得到的错误与->找不到库libcrypto
我理解这个问题，但我想不出解决办法。我需要更新lambda配置还是需要升级Python库？

使用上面的Dockerfile尝试docker build会导致失败

异常发生在https://github.com/wbond/oscrypto/blob/1.3.0/oscrypto/_openssl/_libcrypto_cffi.py
通过oscrypto._ffi跟踪，问题归结为使用ctypes库打开libcrypto的问题：
>>> import ctypes.util
>>> ctypes.util.find_library('crypto')
>>>
为什么？因为/usr/lib只有libcrypto.so.1.1，而没有指向它的libcrypto.so符号链接。只需在Dockerfile中添加一行即可轻松修复：
RUN ln -s libcrypto.so.1.1 /usr/lib/libcrypto.so
之后Python的ctypes的行为：
>>> from ctypes.util import find_library
>>> find_library('crypto')
'libcrypto.so.1.1'
oscrypto:也是如此
>>> from oscrypto import asymmetric
>>>
根据oscrypto文档，您应该使用相应.so文件的libcrypto和libssl路径调用oscrypto.use_openssl()：
oscrypto.use_openssl(libcrypto_path="/usr/lib/libcrypto.so", libssl_path="/usr/lib/libssl.so")
