Java如何读取PFX密钥文件？

public ReadPFX (){

//转换成十六进制字符串

String stmp="";
for (int n=0;nb.length;n++) {
stmp=(java.lang.Integer.toHexString(b[n] 0XFF));
if (stmp.length()==1) hs=hs+"0"+stmp;
else hs=hs+stmp;
//if (nb.length-1) hs=hs+":";
}
return hs.toUpperCase();
}

int temp = number;
byte[] b=new byte[4];
for (int i=b.length-1;i-1;i--){
b[i] = new Integer(temp0xff).byteValue();//将最高位保存在最低位

private PrivateKey GetPvkformPfx(String strPfx, String strPassword){

// If the keystore password is empty(""), then we have to set
// to null, otherwise it won't work!!!
char[] nPassword = null;

nPassword = null;
}
else
{
nPassword = strPassword.toCharArray();
}
ks.load(fis, nPassword);
fis.close();
System.out.println("keystore type=" + ks.getType());
// Now we loop all the aliases, we need the alias to get keys.
// It seems that this value is the "Friendly name" field in the
// detals tab -- Certificate window -- view -- Certificate
// Button -- Content tab -- Internet Options -- Tools menu
// In MS IE 6.
Enumeration enumas = ks.aliases();
String keyAlias = null;
if (enumas.hasMoreElements())// we are readin just one certificate.
{
keyAlias = (String)enumas.nextElement();
System.out.println("alias=[" + keyAlias + "]");
}
// Now once we know the alias, we could get the keys.
System.out.println("is key entry=" + ks.isKeyEntry(keyAlias));
PrivateKey prikey = (PrivateKey) ks.getKey(keyAlias, nPassword);
Certificate cert = ks.getCertificate(keyAlias);
PublicKey pubkey = cert.getPublicKey();
System.out.println("cert class = " + cert.getClass().getName());
System.out.println("cert = " + cert);
System.out.println("public key = " + pubkey);

java客户端怎么访问带有pfx格式证书的https网站（服务器）呢，
使用HttpURLConnection 访问https地址。
以下是导入JKS证书的方式，可以参考。
String keystorefile = "file";
String keystorepw = "password";
String keypw = "password";
KeyStore keystore = KeyStore.getInstance("JKS");
keystore.load( new FileInputStream(keystorefile), keystorepw.toCharArray());
KeyManagerFactory keymanagerfactory = KeyManagerFactory.getInstance("SunX509");
keymanagerfactory.init(keystore, keypw.toCharArray());
KeyManager akeymanager[] = keymanagerfactory.getKeyManagers();
TrustManagerFactory trustmanagerfactory = TrustManagerFactory.getInstance("SunX509");
trustmanagerfactory.init(keystore);
TrustManager atrustmanager[] = trustmanagerfactory.getTrustManagers();
sslcontext = SSLContext.getInstance("TLS");
sslcontext.init(akeymanager, atrustmanager, null);
sslSocketFactory = sslcontext.getSocketFactory();
String url = "asdfdf";
URL testURL = new URL(url);
HttpURLConnection urlConnection = (HttpURLConnection) testURL.openConnection();
if (urlConnection instanceof HttpsURLConnection) {
HttpsURLConnection conn = (HttpsURLConnection) urlConnection;
conn.setSSLSocketFactory(sslSocketFactory);
}
如何在Java处理PFX格式证书
开发人员通常需要将PFX文件转换为某些不同的格式，如PEM或JKS，以便可以为使用SSL通信的独立Java客户端或WebLogic Server使用
在Security编程中，有几种典型的密码交换信息文件格式:
DER-encoded certificate: .cer, .crt
PEM-encoded message: .pem
PKCS#12 Personal Information Exchange: .pfx, .p12
PKCS#10 Certification Request: .p10
PKCS#7 cert request response: .p7r
PKCS#7 binary message: .p7b
