PFClean relies on HTTPS to securely connect to The Pixel Farm's servers and access all online features.

On Linux this is implemented using the free OpenSSL library, version 1.1 or higher. OpenSSL 1.0 is not supported and cannot be used.

OpenSSL requirements for Rocky Linux 8/9

When installing PFClean on Rocky Linux 8 or 9, the OpenSSL libraries come installed as a standard part of the operating system. On Rocky Linux 8, this is OpenSSL 1.1 and on Rocky Linux 9 it is OpenSSL 3.

If you do not have a compatible version of OpenSSL already installed on your computer, please consult your Linux system administrator or operating system documentation for further assistance.

The PFClean installer will report which version of OpenSSL it will be using at the end of the installation process.

Manual override for Linux OpenSSL version

The version of OpenSSL installed on your computer may be different from the operating system default. If so, the PFClean installer may not be able to automatically detect the correct version available on your computer.

In this case, you can tell the PFClean installer which version to use by passing a command line argument to the installer:

pfclean-installer.run -- openssl3

to use OpenSSL 3, or:

pfclean-installer.run -- openssl1.1

to use OpenSSL 1.1. Replace pfclean-installer.run with the filename of your current installer.
