证书生成

    Linux环境安装了openssl组件。

    1. 搭建CA环境。

    2. 生成根私钥。

      2. openssl genrsa -aes256 -out demoCA/private/cakey.pem 2048
      3. Generating RSA private key, 2048 bit long modulus
      4. .................+++
      5. ..................+++
      6. e is 65537 (0x10001)
      7. --设置根私钥的保护密码，假设为Test@123
      8. Enter pass phrase for demoCA/private/cakey.pem:
      9. --再次输入私钥密码 Test@123
      10. Verifying - Enter pass phrase for demoCA/private/cakey.pem:

    3. 生成根证书请求文件。

      1. --生成CA根证书申请文件careq.pem
      2. openssl req -config openssl.cnf -new -key demoCA/private/cakey.pem -out demoCA/careq.pem
      3. Enter pass phrase for demoCA/private/cakey.pem:
      4. --输入根私钥密码 Test@123
      5. You are about to be asked to enter information that will be incorporated
      6. into your certificate request.
      7. What you are about to enter is what is called a Distinguished Name or a DN.
      8. There are quite a few fields but you can leave some blank
      9. For some fields there will be a default value,
      10. If you enter '.', the field will be left blank.

      去掉私钥密码保护，方法如下：

    4. 生成客户端证书和客户端私钥的方法和要求与服务器相同。

      1. --生成客户端私钥
      2. openssl genrsa -aes256 -out client.key 2048
      3. --生成客户端证书请求文件
      4. openssl req -config openssl.cnf -new -key client.key -out client.req 
      5. --对生成的客户端证书请求文件进行签发，签发后将生成正式的客户端证书client.crt
      6. openssl ca -config openssl.cnf -in client.req -out client.crt -days 3650 -md sha256

      去掉私钥密码保护，方法如下：

      1. --去掉客户端私钥的密码保护
      2. openssl rsa -in client.key -out client.key
      3. --如果不去掉客户端私钥的密码保护需要使用gs_guc工具对存储密码进行加密保护
      4. gs_guc encrypt -M client -D ./

      将客户端密钥转化为DER格式，方法如下：

      1. openssl pkcs8 -topk8 -outform DER -in client.key -out client.key.pk8 -nocrypt

    5. 吊销证书列表的生成。

      如果需要吊销列表，可按照如下方法生成：
