.pfx數(shù)字證書制作及操作使用
公司業(yè)務(wù)擴展，要對外開放接口，由于數(shù)據(jù)的安全性，主要是公司是賣數(shù)據(jù)的，需要對接口進行驗證，于是使用數(shù)字證書進行加密解密對數(shù)據(jù)進行處理，防止篡改接口請求，非法獲取數(shù)據(jù)，于是整理數(shù)字證書使用與制做。
創(chuàng)建.pfx
在options.config文件中設(shè)置證書有效期
<?xml version="1.0" encoding="utf-8" ?>
<options>
<outputPath>output</outputPath>
<start>2022/7/22</start>
<end>2030/12/31</end>
</options>
CN=名稱(一般填公司名稱)
OU=單位名稱
O=作者名稱
L=地區(qū)
C=國家
CN=*****，OU=技術(shù)部，O=**，L=北京，ST=北京，C=CN
第一步打開CertManager.exe
第二步
1、輸入組織名稱
2、輸入pvk名稱
3、輸入cer名稱
4、完成以上步驟后回車彈出創(chuàng)建私鑰密碼對話框
輸入密碼并且記住，確定之后再次確認密碼
第三步
1、輸入spc名稱
2、輸入密碼
3、輸入pfx名稱
4、輸入密碼并牢記
5、出現(xiàn)succeeded表示成功
以上步驟完成會生成文件 output目錄下
從.pfx文件提取秘鑰
通過這個操作，我們能夠獲得所需的密鑰庫文件zlex.keystore。
在output目錄下按住shift鍵右擊鼠標打開命令行
CMD代碼
keytool -importkeystore -v -srckeystore trumgu.pfx -srcstoretype pkcs12 -srcstorepass trumgu123 -destkeystore trumgu.keystore -deststoretype jks -deststorepass trumgu123
- **-importkeystore:**導入密鑰庫，通過格式設(shè)定，我們可以將PKCS#12文件轉(zhuǎn)換為JKS格式。
-v顯示詳情 - **-srckeystore:**源密鑰庫，這里是trumgu.pfx
- **-srcstoretype:**源密鑰庫格式，這里為pkcs12
- **-srcstorepass:**源密鑰庫密碼，這里為trumgu123
- **-destkeystore:**目標密鑰庫，這里為zcs.keystore
- **-deststoretype:**目標密鑰庫格式，這里為jks，默認值也如此
- **-deststorepass:**目標密鑰庫密碼，這里為trumgu123
這時，我們已經(jīng)獲得了密鑰庫文件，只要確定對應(yīng)的別名信息，就可以提取公鑰/私鑰，以及數(shù)字證書，進行加密交互了！
keytool -list -keystore trumgu.keystore -storepass trumgu123 -v
- **-list:**列舉密鑰庫
- **-keystore:**密鑰庫，這里是trumgu.keystore
- **-storepass:**密鑰庫密碼，這里是trumgu123
- **-v:**顯示詳情
記住命令返回的別名
我這里生成的是
pvktmp:48383345-fae0-465f-a4b6-8b2619ddb8a2
導出證書
keytool -exportcert -alias pvktmp:48383345-fae0-465f-a4b6-8b2619ddb8a2 -keystore trumgu.keystore -file trumgu.crt -storepass trumgu123
- **-exportcert:**導出證書
- **-alias:**別名，這里是1
- **-keystore:**密鑰庫，這里是trumgu.keystore
- **-file:**證書文件，這里是trumgu.crt
- **-storepass:**密鑰庫密碼，這里是trumgu123
