    abstract =  {This document defines two methods that make it easier to deploy certificates for proper server identity checking in application protocols. The first method enables a TLS client to obtain a TLS server's end-entity certificate over secure HTTP as an alternative to standard Public Key Infrastructure using X.509 (PKIX) and DNS-Based Authentication of Named Entities (DANE). The second method enables a source domain to securely delegate an application to a derived domain using HTTPS redirects.},
