Is rtmp encryption with nginx + php real?

Question

PHP

Hello, I wanted to clarify whether it is possible to implement rtmp encryption in this way:
rtmp://ip-adress/application/filename/userdata/
1) The name of the application and the file given by the user must be encrypted.
The essence of the work:
Restrict access so that the rtmp link does not work outside the site. and the link was unique for each user and forbid viewing without authorization. (This is not a term paper or homework, but a real project) I just want to know if it is possible to implement it? not to try in vain.
Thanks in advance!
