Sebastian Krause fastslo<\/a><\/noindex> kilden til den merkelige inkompatibiliteten med tjenesten Bypass<\/a><\/noindex> skriptet dehydrated<\/a><\/noindex>, brukt for \u00e5 automatisere anskaffelse av TLS-sertifikater via ACME-protokollen. Bypass fungerer b\u00e5de med referansekunden og uacme, men ikke dehydrated (for mer presist, det virker ogs\u00e5 med noen omg\u00e5elser, men utelukkende i dns-1-modus).<\/p>\n

\u00c5rsaken var banal: i stedet for \u00e5 analysere svaret i JSON-format p\u00e5 riktig m\u00e5te, brukte forfatteren dehydrated et spesifikt format for JSON-utdata fra tjenesten Let's Encrypt og utf\u00f8rte analysen med hjelp av regul\u00e6re uttrykk. Men Bypass returnerer ikke vakkert formatert, men minifisert JSON, og det som ble brukt regul\u00e6re uttrykket<\/a><\/noindex> fungerte ikke. Den nevnte tiln\u00e6rmingen utelukker ikke at det kan oppst\u00e5 problemer med LetsEncrypt, dersom denne tjenesten i fremtiden endrer formatet uten varsling, og fortsatt er innenfor rammene av den offisielle protokollen.<\/p>\n

Under diskusjonen av problemet ble det foresl\u00e5tt \u00e5 bruke en ekstern JSON-parsere, slik som json_pp<\/a><\/noindex> eller jq<\/a><\/noindex> (legg til i pipe 'jq -r \u00ab.authorizations | .[]\u00bb' for korrekt analyse).
\nUlempen med en slik tiln\u00e6rming er at den svakner ideen om \u00e5 klare seg med minimale og lett verifiserbare midler, samt problemer med feilh\u00e5ndtering.<\/p>\n

Forfatteren av prosjektet dehydrated (prosjektet ble nylig solgt<\/a><\/noindex> til selskapet Apilayer GmbH) godkjente<\/a><\/noindex>, at analysen av JSON er et stort problem, men \u00e5 legge til eksterne parserne anser han ikke som en god id\u00e9, da en av hovedfordelene med skriptet er frav\u00e6ret av avhengigheter. For \u00f8yeblikket er han opptatt, men h\u00e5per \u00e5 gi oppmerksomhet til l\u00f8sning av problemet innen de neste dagene. I planene er det merket om \u00e5 redesigne JSON-parseren eller integrere en ferdig parser p\u00e5 shell-spr\u00e5k. JSON.sh<\/a><\/noindex>.<\/p>\n
