解决自签名证书在Chrome上的“不是私密连接问题”

一、生成证书

1、创建根证书

新建MyCompanyCA.cnf文件并输入以下内容:

[ req ]
distinguished_name  = req_distinguished_name
x509_extensions     = root_ca

[ req_distinguished_name ]

# 以下内容可随意填写
countryName = CN (2 letter code)
countryName_min = 2
countryName_max = 2
stateOrProvinceName = ZheJiang
localityName = HangZhou
organizationName = Mycompany
organizationalUnitName = technology
commonName = develop
commonName_max = 64
emailAddress = xxxxxxxx@gmail.com
emailAddress_max = 64

[ root_ca ]
basicConstraints = critical, CA:true

新建MyCompanyLocalhost.ext文件并输入以下内容:

subjectAltName = @alt_names
extendedKeyUsage = serverAuth

[alt_names]

# 域名，如有多个用DNS.2,DNS.3…来增加
DNS.1 = domain.com 
# IP地址
IP.1 = 127.0.0.1

说明:
MyCompanyCA.cnf文件是为申请CA根证书的配置文件;
MyCompanyLocalhost.ext是生成服务器证书的扩展配置文件;

2、生成证书

执行以下3条命令:

openssl req -x509 -newkey rsa:2048 -out MyCompanyCA.cer -outform PEM -keyout MyCompanyCA.pvk -days 10000 -verbose -config MyCompanyCA.cnf -nodes -sha256 -subj "/CN=MyCompany CA"

openssl req -newkey rsa:2048 -keyout MyCompanyLocalhost.pvk -out MyCompanyLocalhost.req -subj /CN=localhost -sha256 -nodes

openssl x509 -req -CA MyCompanyCA.cer -CAkey MyCompanyCA.pvk -in MyCompanyLocalhost.req -out MyCompanyLocalhost.cer -days 10000 -extfile MyCompanyLocalhost.ext -sha256 -set_serial 0x1111

执行完成后，会得到，其中MyCompanyCA.cer是用来安装在浏览器、安卓和苹果设备上，MyCompanyLocalhost.cer和MyCompanyLocalhost.pvk是放在服务端的证书和key文件，在Nginx中配置即可.

-rw-r--r--  1 hugh  staff   1.0K  3  5 15:20 MyCompanyCA.cer
-rw-r--r--  1 hugh  staff   592B  3  5 16:03 MyCompanyCA.cnf
-rw-r--r--  1 hugh  staff   1.6K  3  5 15:20 MyCompanyCA.pvk
-rw-r--r--  1 hugh  staff   1.0K  3  5 15:20 MyCompanyLocalhost.cer
-rw-r--r--  1 hugh  staff   116B  3  5 15:20 MyCompanyLocalhost.ext
-rw-r--r--  1 hugh  staff   1.6K  3  5 15:20 MyCompanyLocalhost.pvk
-rw-r--r--  1 hugh  staff   891B  3  5 15:20 MyCompanyLocalhost.req

二、在设备上安装证书

以mac为例，直接双击MyCompanyCA.cer文件或者在钥匙串中导入证书，证书导入后，默认状态如下:

打开“信任”并选择“永远相信”

打开要访问的地址已经变为绿色”安全”
