Verifying a JWT signature

seamore · 04-20-2022, 05:27 PM

I would like to create my own JWT signature to compare with the original. I see the following code on several sites:

HMACSHA256(
base64UrlEncode(header) + "." +
base64UrlEncode(payload),
*secret base64 encoded*
)

There is no detail on what imports I need or code prior to this.
I have the three elements, just need help getting to the point to use the above.

Have you, like, somehow not considered linking to the sites? Really? How can that be?

Here is an example

Please disregard this post.
I now find that the code I posted is "pseudo code"

Please review the Site FAQ for guidance in asking well formed questions. Especially visit the link from that page, How to Ask Questions the Smart Way for discussion of things to consider when asking others for help.

Let me ask an excellent question:

Why?
