常熟董浜招聘:征服*.PFX(*.p12)——个人信息交换文件

征服*.PFX(*.p12)——个人信息交换文件

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

1. echo 格式转换   
2. keytool -importkeystore -v  -srckeystore zlex.pfx -srcstoretype pkcs12 -srcstorepass 123456 -destkeystore zlex.keystore -deststoretype jks -deststorepass 123456  

echo 格式转换keytool -importkeystore -v  -srckeystore zlex.pfx -srcstoretype pkcs12 -srcstorepass 123456 -destkeystore zlex.keystore -deststoretype jks -deststorepass 123456

1. echo 查看证书   
2. keytool -list -keystore zlex.keystore -storepass 123456 -v  

echo 查看证书keytool -list -keystore zlex.keystore -storepass 123456 -v

1. echo 导出证书   
2. keytool -exportcert -alias 1 -keystore zlex.keystore -file zlex.crt -storepass 123456  

echo 导出证书keytool -exportcert -alias 1 -keystore zlex.keystore -file zlex.crt -storepass 123456
