Créer un certificat auto-signé avec subjectAltName pour corriger [missing_subjectAltName] dans Chrome 58+

J'essaie de créer un certificat auto-signé pour localhostcontenir subjectAltNamepour satisfaire Chrome 58+:

createcertificate.sh:

#!/usr/bin/env bash
filename="$1server"
openssl req -new -sha256 -nodes -out ./../nginx/ssl/${filename}.csr -newkey rsa:2048 -keyout ./../nginx/ssl/${filename}.key -config <( cat ${filename}_csr.txt )
openssl x509 -req -in ./../nginx/ssl/${filename}.csr -CA ~/ssl/rootCA.pem -CAkey ~/ssl/rootCA.key -CAcreateserial -out ./../nginx/ssl/${filename}.crt -days 500 -sha256

server_csr.txt:

[req]
default_bits = 2048
prompt = no
default_md = sha256
req_extensions = req_ext
distinguished_name = dn

[ dn ]
C=US
ST=New York
L=Rochester
O=End Point
OU=Testing Domain
emailAddress=your-administrative-address@your-awesome-existing-domain.com
CN = localhost

[ req_ext ]
subjectAltName = @alt_names

[ alt_names ]
DNS.1 = localhost

Appeler ./createcertificate.sh:

Enter pass phrase for /home/alexzeitler/ssl/rootCA.key:

Mais Chrome 58 refuse toujours le certificat:

This server could not prove that it is localhost; its security certificate is from [missing_subjectAltName]. This may be caused by a misconfiguration or an attacker intercepting your connection.

Le .crtne contient pas le Subject Alternative Name.

En lisant la documentation de subjectAltName, j'ai remarqué que mon certificat s'est affiché Version: 1alors que la documentation le montre Version: 3.

Pour obtenir un Version 3certificat, j'ai spécifié l' -extfileoption:

sudo openssl x509 -req -in ./../nginx/ssl/${filename}.csr -CA ~/ssl/rootCA.pem -CAkey ~/ssl/rootCA.key -CAcreateserial -out ./../nginx/ssl/${filename}.crt -days 500 -sha256 -extfile v3.ext

v3.ext ressemble à ça:

authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
subjectAltName = @alt_names

[alt_names]
DNS.1 = localhost

Lors de la openssl x509 -text -in ../nginx/ssl/server.crt -nooutnouvelle exécution , le certificat contient désormais également la Subject Alternative Namesection:

J'ai également créé un article de blog .

Si vous souhaitez ajouter 127.0.0.1, vous devez écrire:

[alt_names]
IP.1 = 127.0.0.1

Si vous ajoutez DNS.1 = 127.0.0.1Chrome, vous retournerez a ERR_CERT_COMMON_NAME_INVALID.

Merci à @Robar de l'avoir signalé dans les commentaires.

Sous Windows, enregistrez ce script dans votre dossier SSL en tant que makeCert.bat. Le certificat auto-signé qu'il crée satisfera aux exigences de Chrome ver 58+ pour SAN (Subject Alternative Name).

Ce script va créer ces fichiers: example.cnf, example.crt, example.key

J'ai mis à jour le fichier batch de STWilson pour supprimer les éléments COM car localhost n'a pas vraiment cela et je veux un certificat SSL localhost auto-signé pour le développement. J'ai également ajouté quelques fichiers supplémentaires comme un fichier .pfx et .pem.key.

Des trucs comme ça vont toujours /usr/local/bin.
