Verify Cookies signature

System Information
  • Strapi Version: 3.6.5
  • Operating System: 20.04
  • Database: MySQL
  • Node Version: 10.19.0
  • NPM Version: 7.18.1
  • Yarn Version: 1.22.10

Hello, how do I verify the cookie from it’s signature?

The behaviour:

I set a cookie from Strapi using

ctx.cookies.set("token", token, {
          domain: ""

After this I get in return, a set cookie header for my “token” cookie and another for “token.sig”
Then I made a research so I find out that it should be signed automaticly using Keygrip but I do not find a way to verify that it’s valid.

So, now I ask about how do I verify it propperly using some library that already comes with Strapi base.

Thanks in advance
