#创建.pfx
CN=名称(一般填公司名称)
OU=单位名称
O=作者名称
L=地区
C=国家第一步打开CertManager.exe
第二步
第三步
以上步骤操作完成之后会生成以下文件
#从.pfx文件提取密钥*
方法:
1:通过keytool密钥库导入命令importkeystore，将密钥库格式由 PKCS#12转换为JKS。
2:检索新生成的密钥库文件，提取别名信息。
3:由密钥库文件导出数字证书（这里将用到别名）。
4:通过代码提取公钥/私钥、签名算法等.
CMD代码
keytool -importkeystore -v -srckeystore zcs.pfx -srcstoretype pkcs12 -srcstorepass 12345678 -destkeystore zcs.keystore -deststoretype jks -deststorepass 12345678
######=================================================================
**-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zcs.pfx
**-srcstoretype:**源密钥库格式，这里为pkcs12
**-srcstorepass:**源密钥库密码，这里为12345678
**-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12345678
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
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！
CMD代码
keytool -list -keystore zcs.keystore -storepass 12345678 -v
**-list:**列举密钥库
**-keystore:**密钥库，这里是zcs.keystore
**-storepass:**密钥库密码，这里是12345678
**-v:**显示详情
现在可以导出证书了
CMD代码
keytool -exportcert -alias pvktmp:4c306f24-9992-446d-a334-82e8be541ca5 -keystore zcs.keystore -file zcs.crt -storepass 12345678
**-exportcert:**导出证书
**-alias:**别名，这里是1
**-keystore:**密钥库，这里是zcs.keystore
**-file:**证书文件，这里是zcs.crt
**-storepass:**密钥库密码，这里是12345678
最后上Java代码:
