【日用】获取pfx证书序列号[通俗易懂]

大家好，又见面了，我是你们的朋友全栈君。

一、使用java代码

package com.sanglp.util;
import java.io.ByteArrayInputStream;
import java.io.File;
import java.io.IOException;
import java.math.BigInteger;
import java.security.KeyStore;
import java.security.cert.X509Certificate;
import java.util.Enumeration;
import org.apache.commons.io.FileUtils;
/** * * @author yang6 从pfx文件里面读取信息 * */
public class ReadPFX { 

// 先得到keyStore
private static KeyStore getKeyStore(byte[] pfxData, String password) throws Exception { 

KeyStore keystore = KeyStore.getInstance("PKCS12");
keystore.load(new ByteArrayInputStream(pfxData), password.toCharArray());
return keystore;
}
// x509证书
public static X509Certificate getX509Certificate(byte[] pfxData, String password) throws Exception { 

X509Certificate x509Certificate = null;
KeyStore keystore = getKeyStore(pfxData, password);
Enumeration<String> enums = keystore.aliases();
String keyAlias = "";
while (enums.hasMoreElements()) { 

keyAlias = enums.nextElement();
if (keystore.isKeyEntry(keyAlias)) { 

x509Certificate = (X509Certificate) keystore.getCertificate(keyAlias);
}
}
return x509Certificate;
}
// 得到操作员的证书序列号
public static String getOpertatorSn(String strPfx, String strPassword) { 

File pfxFile = new File(strPfx);
String opertatorSn = null;
try { 
 // org.apach.commons.io
X509Certificate cert = getX509Certificate(FileUtils.readFileToByteArray(pfxFile), strPassword);
BigInteger serialNumbers = cert.getSerialNumber();
opertatorSn = serialNumbers.toString(16); // 转十六进制
} catch (IOException e) { 

// TODO Auto-generated catch block
e.printStackTrace();
} catch (Exception e) { 

// TODO Auto-generated catch block
e.printStackTrace();
}
return opertatorSn;
}
public static void main(String[] args) { 

System.out.println(getOpertatorSn("D://79813821473.pfx", "111111"));
}
}

二、使用脚本

#!/bin/sh
PFX=$1
openssl pkcs12 -in $PFX.pfx -nodes -out $PFX.pem
openssl rsa -in $PFX.pem -out $PFX.key
openssl x509 -in $PFX.pem -out $PFX.crt
openssl x509 -noout -text -in $PFX.crt

方式二使用的时候需要执行脚本，并输入证书的名称（不需要.pfx后缀）
