For those of you who haven’t seen my various conference talks about Namecoin TLS, AIA (Authority Information Access) is a mechanism for a TLS certificate to provide a URL where you can find the certificate of its issuer. Namecoin does some, uh, creative things with AIA. For reasons that will be elaborated on in a future post (don’t worry, all will be explained there), I wanted to know the maximum length of the URL that AIA can link to.
