.pfx数字证书制作及操作使用

公司业务扩展，要对外开放接口，由于数据的安全性，主要是公司是卖数据的，需要对接口进行验证，于是使用数字证书进行加密解密对数据进行处理，防止篡改接口请求，非法获取数据，于是整理数字证书使用与制做。

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=*****，OU=技术部，O=**，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

gateway加密认证

*.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
