A clear and concise description of what the problem is. E.g. I'm always frustrated when [...]

I often use cyberchef for the simple UI it has with the following recipe:
https://gchq.github.io/CyberChef/#recipe=Register('(?%3C%3Dnumber:%5C%5Cs)(.*)',true,false,false)Register('(?%3C%3Dlength:%5C%5Cs)(.*)',true,false,false)HTTP_request('GET','https://makemeapassword.ligos.net/api/v1/alphanumeric/plain?c%3D$R0%26l%3D$R1%26sym%3D1','','Cross-Origin%20Resource%20Sharing',false)Add_line_numbers()Find_/_Replace(%7B'option':'Regex','string':'%5C%5Cs'%7D,'',true,false,true,false)&input=bnVtYmVyOiAxCmxlbmd0aDogMjAK

It utilizes an external service (makemeapassword) for password generation.

Describe the solution you'd like
A clear and concise description of what you want to happen.

I would like any sort of random generation algorithm to utilize alongside many of the parsers/transformation tools from Cyberchef

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Currently the alternative is the one aforementioned, where I use an external service response and manipulate it.
