Christian Heimes added the comment: pyenv uses default value for ./configure --with-ssl-default-suites. You have to use --with-ssl-default-suites=openssl so your build uses the system's crypto policy correctly. -- ___ Python tracker

Adam added the comment: Many thanks Christian, see the attached for the output of the commands on Python 3.9.10 and 3.10.2, along with a diff removing version numbers and memory addresses. I've run the commands on the Ubuntu distribution, we can also run the same for the Centos VM, if

Adam added the comment: Update, the Pyenv team confirmed that they do not install OpenSSL in linux, its only installed for MacOS, and it should be built using the system OpenSSL within Linux. We're investigating further to attempt to debug the issue. Interestingly the OpenSSL build flags

Adam added the comment: Yes agreed, it may well be a Pyenv issue. Interestingly we can demonstrate that the global OpenSSL crypto policies is respected with the 3.9.10 version, through adjusting the policy. The ssl error occurs with the default policy setting and is resolved with the legacy

Christian Heimes added the comment: This is a pyenv issue, not a Python issue. Custom builds of OpenSSL typically do not and cannot use global settings like crypto policies. They are missing distro downstream patches and use different config files. --

[issue46863] Python 3.10 OpenSSL Configuration Issues

Adam added the comment: I found the Python build recipes and Pyenv does appear to install OpenSSL from source. The only difference I can see, aside from the Python version, is an update on the OpenSSL versions; openssl-1.1.1l (3.9.10) to openssl-1.1.1k (3.10.2). The OpenSSL release notes do

Adam added the comment: Thanks for the quick reply. On both Ubuntu and Centos, I’m installing Python using Pyenv, testing with 3.9.10 and 3.10.2. Pyenv provides a verbose install flag, I can rebuild the Python versions and review the build commands, if helpful? I’m testing with clean Linux

Christian Heimes added the comment: How did you build Python 3.10? Neither CentOS 8 nor Ubuntu 20.04 come with Python 3.10. Does your build of Python use system's OpenSSL build? -- assignee: christian.heimes -> ___ Python tracker

[issue46863] Python 3.10 OpenSSL Configuration Issues

New submission from Adam Pinckard : Python 3.10 does not appear to respecting the OpenSSL configuration within linux. Testing completed using Pyenv on both Ubuntu 20.04.4 and Centos-8. Note PEP 644 which requires OpenSSL >= 1.1.1 is released in Python 3.10. We operate behind a corporate proxy
