Android SSL BKS证书生成, 以及PFX与JKS证书的转换

一.Android SSL BKS 证书生成过程
1.生成服务器jks证书:
keytool -genkey -alias peer -keystore peer.jks
2.导出cert证书:
keytool -exportcert -alias peer -file peer.cert -keystore peer.jks
3.生成Android客户端bks证书
需要用到 bcprov-ext-jdk15on-151.jar , 官网:http://www.bouncycastle.org/latest_releases.html
将jar包放到 %JAVA_HOME%\jre\lib\security
keytool -importcert -keystore peer.bks -file peer.cert -storetype BKS -provider org.bouncycastle.jce.provider.BouncyCastleProvider
二.PFX与JKS证书的转换
工具类:
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.security.Key;
import java.security.KeyStore;
import java.security.cert.Certificate;
import java.util.Enumeration;
public class CertificateConvertUtil {
public static final String PKCS12 = "PKCS12";
public static final String JKS = "JKS";
/**
* pkcs12 转 jks
* @param input_keystore_file pkcs12证书路径
* @param keystore_password pkcs12证书密钥库口令
* @param ouput_keystore_file jks证书路径
*/
public static void PKCS12ToJKS(String input_keystore_file,
String keystore_password, String ouput_keystore_file) {
try {
KeyStore inputKeyStore = KeyStore.getInstance(PKCS12);
FileInputStream fis = new FileInputStream(input_keystore_file);
char[] nPassword = null;
if ((keystore_password == null)
|| keystore_password.trim().equals("")) {
nPassword = null;
} else {
nPassword = keystore_password.toCharArray();
}
inputKeyStore.load(fis, nPassword);
fis.close();
System.out.println("keystore type=" + inputKeyStore.getType());
KeyStore outputKeyStore = KeyStore.getInstance(JKS);
outputKeyStore.load(null, nPassword);
Enumeration enums = inputKeyStore.aliases();
while (enums.hasMoreElements()) {
String keyAlias = (String) enums.nextElement();
System.out.println("alias=[" + keyAlias + "]");
if (inputKeyStore.isKeyEntry(keyAlias)) {
Key key = inputKeyStore.getKey(keyAlias, nPassword);
Certificate[] certChain = inputKeyStore
.getCertificateChain(keyAlias);
outputKeyStore.setKeyEntry(keyAlias, key, nPassword,
certChain);
}
FileOutputStream out = new FileOutputStream(ouput_keystore_file);
outputKeyStore.store(out, nPassword);
out.close();
outputKeyStore.deleteEntry(keyAlias);
System.out.println("convert is finished!");
}
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* jks 转 pkcs12
* @param input_keystore_file jks证书路径
* @param keystore_password jks证书密钥库口令
* @param ouput_keystore_file pkcs12证书路径
*/
public static void JKSToPKCS12(String input_keystore_file,
String keystore_password, String ouput_keystore_file) {
try {
KeyStore inputKeyStore = KeyStore.getInstance(JKS);
FileInputStream fis = new FileInputStream(input_keystore_file);
char[] nPassword = null;
if ((keystore_password == null)
|| keystore_password.trim().equals("")) {
nPassword = null;
} else {
nPassword = keystore_password.toCharArray();
}
inputKeyStore.load(fis, nPassword);
fis.close();
System.out.println("keystore type=" + inputKeyStore.getType());
KeyStore outputKeyStore = KeyStore.getInstance(PKCS12);
outputKeyStore.load(null, nPassword);
Enumeration enums = inputKeyStore.aliases();
while (enums.hasMoreElements()) {
String keyAlias = (String) enums.nextElement();
System.out.println("alias=[" + keyAlias + "]");
if (inputKeyStore.isKeyEntry(keyAlias)) {
Key key = inputKeyStore.getKey(keyAlias, nPassword);
Certificate[] certChain = inputKeyStore
.getCertificateChain(keyAlias);
outputKeyStore.setKeyEntry(keyAlias, key, nPassword,
certChain);
}
FileOutputStream out = new FileOutputStream(ouput_keystore_file);
outputKeyStore.store(out, nPassword);
out.close();
outputKeyStore.deleteEntry(keyAlias);
System.out.println("convert is finished!");
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
使用工具类进行转换时, 会将 证书Alias 输出到控制台.
测试代码:
public static void main(String[] args) { CertificateConvertUtil.PKCS12ToJKS("D:/peer.pfx", "123456", "D:/peer.jks"); }
