How license meets inclusion principles

The license grants all rights and only requires retaining a copyright header in redistributed sources.
This license is used in a package which is going to be added to Fedora Linux distribution.
Fedora finds the license acceptable https://gitlab.com/fedora/legal/fedora-license-data/-/issues/329.

The license text:

The author hereby grants a perpetual license to everybody to 
use this code for any purpose as long as the copyright message is included 
in the source code of this or any derived work. 
 
Yes, this means that you, your company, your club, and anyone else 
can use this code anywhere you want. You can change it and distribute it 
under the GPL, include it in your commercial product without releasing 
the source code, put it on the web, etc.  
The only thing you cannot do is remove my copyright message,  
or distribute any source code based on this implementation that does not  
include my copyright message.  
  
I appreciate a mention in the documentation or credits,  
but I understand if that is difficult to do. 
I also appreciate it if you tell me where and why you used my code.

The license has no official name or an abbreviation. Please suggest them.

[swinslow]

I'm +1 to add, as a historical and permissive (if informal) license used in Fedora.

For name I'd probably suggest going with Ferguson-Twofish as the ID and "Ferguson Twofish License" as the name.

[jlovejoy]

agree with @swinslow (also discussed on 9/8 working session)
