My LetsEncrypt account id is: 77079176
I am trying to use a fixed ACME account id with cert-manager and LetsEncrypt in order to have higher rate limits across multiple Kubernetes clusters.
I am trying to follow the documentation for ExternalAccountBindings here: https://cert-manager.io/docs/configuration/acme/#external-account-bindings
For reference: External Account Bindings require three fields on an ACME
Issuer which represents your ACME account. These fields are; the
keyID of which your external account binding is indexed by the external account manager,
keySecretRef which references a secret containing a base 64 encoded URL string of your external account symmetric MAC key, and finally
keyAlgorithm , the MAC algorithm used to sign the JSON web string containing your External Account Binding when registering the account with the ACME server.
I have my account id, but I do not know the MAC key, or its algorithm.
Cert-manager version is 1.16.
How can I locate this information?
