.pfx数字证书制作及操作使用

创建.pfx

在options.config文件中设置证书有效期

<?xml version="1.0" encoding="utf-8" ?>
<options>
  <outputPath>output</outputPath>
  <start>2022/7/22</start>
  <end>2030/12/31</end>
</options>

CN=名称(一般填公司名称) OU=单位名称 O=作者名称 L=地区 C=国家

CN=川谷金融科技，OU=技术部，O=田略，L=北京，ST=北京，C=CN

第一步打开CertManager.exe 第二步 1、输入组织名称 2、输入pvk名称 3、输入cer名称 4、完成以上步骤后回车弹出创建私钥密码对话框输入密码并且记住，确定之后再次确认密码第三步 1、输入spc名称 2、输入密码 3、输入pfx名称 4、输入密码并牢记 5、出现succeeded表示成功以上步骤完成会生成文件 output目录下

从.pfx文件提取秘钥

通过这个操作，我们能够获得所需的密钥库文件zlex.keystore。在output目录下按住shift键右击鼠标打开命令行

CMD代码

keytool -importkeystore -v -srckeystore trumgu.pfx -srcstoretype pkcs12 -srcstorepass trumgu123 -destkeystore trumgu.keystore -deststoretype jks -deststorepass trumgu123

**-importkeystore:**导入密钥库，通过格式设定，我们可以将PKCS#12文件转换为JKS格式。 -v显示详情
**-srckeystore:**源密钥库，这里是trumgu.pfx
**-srcstoretype:**源密钥库格式，这里为pkcs12
**-srcstorepass:**源密钥库密码，这里为trumgu123
**-destkeystore:**目标密钥库，这里为zcs.keystore
**-deststoretype:**目标密钥库格式，这里为jks，默认值也如此
**-deststorepass:**目标密钥库密码，这里为trumgu123

这时，我们已经获得了密钥库文件，只要确定对应的别名信息，就可以提取公钥/私钥，以及数字证书，进行加密交互了！

keytool -list -keystore trumgu.keystore -storepass trumgu123 -v

** -list: **列举密钥库
**-keystore:**密钥库，这里是trumgu.keystore
**-storepass:**密钥库密码，这里是trumgu123
**-v:**显示详情

记住命令返回的别名我这里生成的是 pvktmp:48383345-fae0-465f-a4b6-8b2619ddb8a2

导出证书

keytool -exportcert -alias pvktmp:48383345-fae0-465f-a4b6-8b2619ddb8a2 -keystore trumgu.keystore -file trumgu.crt -storepass trumgu123

**-exportcert:**导出证书
**-alias:**别名，这里是1
**-keystore:**密钥库，这里是trumgu.keystore
**-file:**证书文件，这里是trumgu.crt
**-storepass:**密钥库密码，这里是trumgu123

*.crt : 证书

*.keystore 秘钥库文件

keyStorePassword: 密钥库密码

aliasPassword: 别名密码

alias: 别名

session 身份识别码

appkey 应用识别码

appName ：名称与证书秘钥库名称一致

timeStamp ：时间戳

sign ：数字签名

需签名字符串 inputStr = appkey=appKeyValue&timeStamp=timeStampValue&参数key=value; 参数的key按accsii排序 post请求参数为JSON转Map后排序再拼接参数为数组直接拼接参数为RequestParam 与GET相同请求为文件上传忽略参数签名

GET请求按accsii排序后拼接

加密获得sign
