  1. the claims section is a certificate, so the format is: <certificate,signature>
  2. the signature uses the private key associated with the certificate, and the signature is across both the certificate and the "body" argument, which is the body of an HTTP request, though could be any arbitrary bytes.

@param cert The pem-encoded certificate @param key The pem-encoded key @param method http method of the request @param uri URI of the request @param body The body of an HTTP request
