What is the "secret key" used in the JWT example in the RFC?

Question

I have been reading the JWT RFC, and in section 3.1 they give an example JWT along with the MAC.

I was wondering if: is it known what is the value of the secret key that they used with SHA-256 to generate the example in RFC?

I want to use the example in a test case so I'd like to reproduce it exactly.

Answer 1

Turns out the key is given in Appendix 1.1 of the draft for "JSON Web Signature (JWS)" in the JSON Web Key format as:

{
    "kty":"oct",
    "k":"AyM1SysPpbyDfgZld3umj1qzKObwVMkoqQ-EstJQLr_T-1qS0gZH75aKtMN3Yj0iPS4hcgUuTwjAzZr1Z9CAow"
}

I misunderstood that the two links named "Appendix A.1" at the end of the "JWT Example" section actually go to different locations. Tha passage with the links is reproduced below:

This computation is illustrated in more detail in Appendix A.1 of [JWS]. See Appendix A.1 for an example of an encrypted JWT.
