Lamnda Python 3.8 GPG解密找不到gpg二进制文件 [英] Lamnda Python 3.8 GPG decryption can not find gpg binary

问题描述

我正在尝试使用lambda函数来解密S3上的文件，我下载了文件没有问题，但是当我尝试对它们进行解密时，找不到gpg.我曾尝试同时使用 python-gnupg 和 gnupg ，但是都没有提到gnupg在操作系统上不可用.在我的以下代码中，用于在python中识别GPG它在python 3.7上运行良好，但是如果我升级到3.8，Lambda使用AMazon Linux 2，而后者不是gpg附带的.我如何才能在Lambda中使用python 3.8来实现cna?

I'm trying to use a lambda function to decrypt files coming to S3, I download the files without issues, but when I try to decrypt them the gpg can not be found. I;ve tried using both python-gnupg and gnupg but both failed mentioning that gnupg is not available on the OS. Below my code for isntantiating GPG in python It works well with python 3.7, but if I upgrade to 3.8, Lambda uses AMazon Linux 2, which doesn't come with gpg. How cna I make it work with python 3.8 in Lambda?

gpg = gnupg.GPG(gnupghome ='/tmp')

错误:

OSError: Unable to run gpg (gnupg) - it may not be available

我发现的所有示例似乎都没有做任何额外的事情.我正在为我的函数包装python-gnugp包和所有其他python包

All the examples I've found don't seem to do anything extra. I'm packaging the python-gnugp package and all other python packages for my function

Lambda中是否提供gpg二进制文件?我该如何进行这项工作?

is the gpg binary available in Lambda? how can I make this work?

推荐答案

您必须捆绑gpg二进制文件及其依赖项，并将其交付到您的包中.在我的程序包中，我将它们捆绑到一个名为"gpg"的文件夹中，然后当我在Lambda函数中使用gpg时，我会这样做:

You have to bundle the gpg binary and its dependencies and deliver them in your package. In my package i bundle them into a folder named 'gpg', then when I use gpg in my Lambda function, I do this:

def lambda_handler(event, context):
    old = os.environ.get("LD_LIBRARY_PATH")
    if old:
        os.environ["LD_LIBRARY_PATH"] = "./gpg" + ":" + old
    else:
        os.environ["LD_LIBRARY_PATH"] = "./gpg"
    
    gpg = gnupg.GPG(gnupghome='/tmp', gpgbinary='./gpg/gpg2', verbose=False)
