Cree un certificado autofirmado con subjectAltName para corregir [missing_subjectAltName] en Chrome 58+

Estoy tratando de crear un certificado autofirmado para localhostcontener subjectAltNameChrome 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 )

server_csr.txt:

[req]
default_bits = 2048

default_md = sha256
req_extensions = req_ext
distinguished_name = dn

[ dn ]

[ req_ext ]

[ alt_names ]
DNS.1 = localhost

Llamada ./createcertificate.sh:

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

Pero Chrome 58 aún rechaza el certificado:

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.

El .crtno contiene el Subject Alternative Name.

Durante la lectura de la documentación para subjectAltName, me di cuenta, que mi certificado ha mostrado Version: 1mientras que el programa de documentación Version: 3.

Para obtener un Version 3certificado, especifiqué la -extfileopción:

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 Se ve como esto:

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

[alt_names]
DNS.1 = localhost

Cuando se ejecuta openssl x509 -text -in ../nginx/ssl/server.crt -nooutnuevamente, el certificado ahora también contiene la Subject Alternative Namesección:

También creé una publicación de blog .

Si desea agregar 127.0.0.1, debe escribir:

[alt_names]
IP.1 = 127.0.0.1

Si agrega DNS.1 = 127.0.0.1Chrome devolverá a ERR_CERT_COMMON_NAME_INVALID.

Gracias a @Robar por señalar esto en los comentarios.

En Windows, guarde este script en su carpeta SSL como makeCert.bat. El certificado autofirmado que realiza satisfará los requisitos de Chrome ver 58+ para SAN (Nombre alternativo del sujeto).

Este script creará estos archivos: example.cnf, example.crt, example.key

He actualizado STWilson archivo por lotes 's para eliminar la materia COM desde localhost en realidad no tiene que y quiero un certificado localhost autofirmado para el desarrollo. También agregué algunos archivos adicionales como un archivo .pfx y .pem.key.
