python3.2 - 错误：root：未找到哈希 md5 的代码

  • 772

我们有一个遗留应用程序，它需要 Python 3.2 版才能工作。为此，我们编译并安装Python 3.2 版。

我们能够在Ubuntu 20.04.1 LTS上成功编译和安装 3.2 版 Python ，但是我们开始遇到使用Python“hashlib”库的问题，如下面的摘录所示......

root@sinj:/usr/local/src/lbginst# /usr/local/lb/py32/bin/python3.2 -c "import hashlib;m=hashlib.md5();print(m.hexdigest())"

问题：我们如何解决提出的问题？

注意 I：在互联网上查阅了数十个资源后，我们开始怀疑与libssl.so libcrypto.so二进制文件有关的某些内容。
注二：我们如何诊断正在发生的事情的信息也非常受欢迎！

谢谢！=D

更新：另一个症状是在构建过程中出现此消息（make，make install）......

Failed to build these modules:
_hashlib           _ssl

  1. 您的问题是您使用的是 OpenSSL 1.1 和不支持该版本 OpenSSL 的旧版 Python。Python 3.2 于 2011 年发布，OpenSSL 1.1.0 于 2016 年发布。

    由于 OpenSSL 1.0 不再受安全支持，您需要将您正在使用的 Python 版本升级到合适的版本。如果您迫不及待并且计划在接下来的三个月内升级，您还可以使用 Ubuntu 16.04 容器，其中包含 Ubuntu 支持的 OpenSSL 1.0，直到 4 月。但是，Python 3.2 也可能存在未修补的漏洞。

    出现指出的问题是因为 python 版本 3.2 与 openssl 版本 1.1 不兼容，openssl 版本是apt-getUbuntu 20.04.1 LTS 使用的标准版本 ( )。

    解决方案是编译并安装 ( make, make install) 版本 1.0 的 openssl，并使用变量“CFLAGS”和“LDFLAGS”配置编译过程，使其使用 openssl 版本 1.0。

    # NOTE: Download, compile and install openssl. By Questor
cd /usr/local/src
wget https://www.openssl.org/source/old/1.0.2/openssl-1.0.2k.tar.gz
tar -zxvf openssl-1.0.2k.tar.gz
cd ./openssl-1.0.2k
./config -fPIC shared
make && make install
cd ..
rm -rf ./openssl-1.0.2k

# NOTE: Download, compile and install Python 3.2. By Questor
cd /usr/local/src
wget https://www.python.org/ftp/python/3.2.2/Python-3.2.2.tgz
tar -zxvf Python-3.2.2.tgz
cd ./Python-3.2.2

eval "./configure --with-threads --enable-shared CFLAGS='-I/usr/local/ssl/include/openssl/ -I/usr/local/ssl/include/' LDFLAGS='-L/usr/local/lib/ -L/usr/local/ssl/lib/ -Wl,-rpath,/usr/local/lib/ -Wl,-rpath,/usr/local/ssl/lib/'"
make && make install
cd ..
rm -rf ./Python-3.2.2

# NOTE: Test python3.2 using "_hashlib" and "_ssl" resources. By Questor
/usr/local/bin/python3.2 -c "import hashlib;m=hashlib.md5();print(m.hexdigest())"

    完毕！谢谢！=D
