Decrypt Asp Net Core Identity cookie on PHP

问题

I use ASP Net Core identity on a domain *.xyz.com, the user can log-in either on xyz.com or aaa.xyz.com, both are on ASP.Net Core and I can share the identity without issue.

I would like to set-up another subdomain like blog.xyz.com based on wordpress. I would like to auto-authenticate on this site, based on the cookie created by ASP. Is it possible to decrypt this cookie in PHP?

This is not about cross-domain issues, but about ASP Net Core identity Cookie decrypt in PHP.
