Sebastian Krause determin\u00f3<\/a><\/noindex> la fuente de una extra\u00f1a incompatibilidad con el servicio Bypass<\/a><\/noindex> del script dehydrated<\/a><\/noindex>, utilizado para automatizar la obtenci\u00f3n de certificados TLS a trav\u00e9s del protocolo ACME. Con Bypass, funcionan tanto el cliente de referencia como uacme, pero no dehydrated (de hecho, tambi\u00e9n funcion\u00f3 con algunos maniobras adicionales, pero exclusivamente en modo dns-1).<\/p>\n

El motivo result\u00f3 ser banal: en lugar de analizar la respuesta en formato JSON adecuadamente, el autor dehydrated utiliz\u00f3 una peculiaridad del formato de salida JSON proporcionado por el servicio Let's Encrypt y realiz\u00f3 el an\u00e1lisis mediante una expresi\u00f3n regular. Pero Bypass devuelve JSON no bonito sino minimizado, y lo utilizado regular<\/a><\/noindex> no funcion\u00f3. El enfoque indicado no descarta la posibilidad de problemas con LetsEncrypt, si este servicio en el futuro cambia el formato de salida sin previo aviso, manteni\u00e9ndose dentro del marco del protocolo oficial.<\/p>\n

Durante la discusi\u00f3n del problema, se sugiri\u00f3 utilizar un analizador JSON externo, como json_pp<\/a><\/noindex> o jq<\/a><\/noindex> (a\u00f1adir al pipe 'jq -r \u00ab.authorizations | .[]\u00bb' para un an\u00e1lisis correcto).
\nLa desventaja de este enfoque es la diluci\u00f3n de la idea de utilizar herramientas m\u00ednimas y f\u00e1cilmente verificables, as\u00ed como problemas con el manejo de errores.<\/p>\n

El autor del proyecto dehydrated (el proyecto fue recientemente vendido<\/a><\/noindex> a la empresa Apilayer GmbH) acord\u00f3<\/a><\/noindex>, que el an\u00e1lisis de JSON es un gran problema, pero no considera buena idea a\u00f1adir analizadores externos, ya que una de las principales virtudes del script es la ausencia de dependencias externas. Actualmente est\u00e1 ocupado, pero espera poder dedicar tiempo a resolver el problema en los pr\u00f3ximos d\u00edas. En sus planes est\u00e1 la reestructuraci\u00f3n del analizador JSON o la integraci\u00f3n de un analizador listo en lenguaje shell \u2014 JSON.sh<\/a><\/noindex>.<\/p>\n
