As of Python 3.10, OpenSSL 1.1.1 or newer is required:
https://www.python.org/dev/peps/pep-0644/ Please guide me in installing
OpenSSL version 1.1.1

Thanks in advance and I look forward to hearing from you.

Hello Kaushal,

the EPEL repository has OpenSSL 1.1 packages available:

# yum install epel-release
# yum install openssl11 openssl11-libs openssl11-devel

If you want to compile software with OpenSSL 1.1 instead of 1.0
you may have to set the proper path or environment variables
such as LDFLAGS.

Hope this helps.

Kind regards,
   Steve
