# 1. 生成一个 RSA 私钥

openssl genrsa -aes256 -out ca_rsa_private.key 4096

执行结果如下：

$ openssl genrsa -aes256 -out ca_rsa_private.key 4096
Generating RSA private key, 4096 bit long modulus (2 primes)

# 2. 创建免密的 RSA 私钥

相比需要输入密码的 RSA 密钥，使用免密的 RSA 密钥，配置在 web 容器中，不需要在每次启动或重新加载配置时手动输入密码（部份 web 容器则直接在配置文件中配置 RSA 密钥的密码）。

openssl rsa -in ca_rsa_private.key -out ca_rsa_private_nopass.key

执行结果如下：

$ openssl rsa -in ca_rsa_private.key -out ca_rsa_private_nopass.key

# 10. 使用 CA 根证书对 https 证书签名请求进行签发

创建的过期时间不要太长，建议不超过2年，否则部份浏览器不会信任该证书，如: iPhone 上的 Safari、Chrome 等。

另外，在 Chrome 58 之后，不再只校验 CommonName 项是否与访问域名或IP匹配，还需要配置 subjectAltName 项。

# 首次使用 CA 根证书签发 https 证书的同时创建 ca.srl 序列号参考文件
# 第二次以后使用 CA 根证书签发 https 证书时直接引用之前创建的 ca.srl 序列号参考文件，并递增其序列号。
