Python 3.9.8、hashlib 和 RIPEMD160

TnT*_*ech 2 openssl macports hashlib python-3.x

运行 MacOS 10.14.6。刚刚运行 MacPorts 更新。采用 Python 3.9.7 -> 3.9.8 和 OpenSSL 1.1.3 -> 3。

运行现有的 Python 代码表明有些东西出问题了hashlib,RIPEMD160 不再可用(Whirlpool 也可能还有其他摘要)。

Traceback (most recent call last):
  File "/opt/local/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/hashlib.py", line 160, in __hash_new
    return _hashlib.new(name, data, **kwargs)
ValueError: [digital envelope routines] initialization error

During handling of the above exception, another exception occurred:

    r160 = hashlib.new('ripemd160')

该方法hashlib.algorithms_available表明hashlibthinkripemd160 可用

并且询问openssl证实它确实具有这种能力。

回滚,同样的问题。我更愿意保留最新的安装。使用 RIPEMD160 是没有商量余地的。

我怀疑提供ports正确的开关、命令、环境变量将说服重新编译工作,但我不知道是什么。

关于发生了什么、如何解决有什么想法吗?

所有旧的加密功能仍然存在于 OpenSSL3 中,但现在需要手动启用。有关详细信息,请参阅OpenSSL github 项目的问题 16994

要快速启用它,请通过运行以下命令找到保存 OpenSSL 配置文件或其符号链接的目录:

openssl version -d

您现在可以转到该目录并编辑配置文件(可能需要使用 sudo):

nano openssl.cnf

确保配置文件包含以下行:

openssl_conf = openssl_init

[openssl_init]
providers = provider_sect

[provider_sect]
default = default_sect
legacy = legacy_sect

[default_sect]
activate = 1

[legacy_sect]

测试环境:OpenSSL 3.0.2、Python 3.10.4、Linux Ubuntu 22.04 LTS aarch64,目前我无法访问其他平台。
