Edit file pairs and assign a random number [closed]

I need ideas for a personal non-profit project, I need to edit pairs of files (ex: a JPEG file and a TXT file) by assigning them the same random number.

The user can upload multiple pairs of files composed as follows:

1.jpeg - 1.txt

2.jpeg - 2.txt

The program must be able to randomize the pairs of files and assign them a random number.

Thanks so much for the answers!
