在我的例子中，我有一个pem文件，其中包含两个证书和一个用于相互SSL身份验证的加密私钥。
我的pem文件是这样的:
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: DES-EDE3-CBC,C8BF220FC76AA5F9
...
-----END RSA PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
以下是我所做的:
将文件拆分为三个单独的文件，这样每个文件只包含一个条目，
以“——BEGIN..”开头，以“——END..”结尾。让我们假设现在有三个文件:cert1。pem cert2。Pem和pkey.pem
pkey进行转换。使用openssl将pem文件转换为DER格式，并执行如下语法:
Openssl pkcs8 -topk8 -nocrypt -in pkey. exepem -out pkey.der -outform DER . pem
注意，如果私钥是加密的，你需要提供一个密码(从原始pem文件的供应商那里获得)
转换为DER格式，
Openssl会像这样要求你输入密码:“enter a pass phrase for pkey。pem:“
如果转换成功，您将得到一个名为“pkey.der”的新文件。
创建一个新的java密钥存储库，并导入私钥和证书:
String keypass = "password"; // this is a new password, you need to come up with to protect your java key store file
String defaultalias = "importkey";
KeyStore ks = KeyStore.getInstance("JKS", "SUN");
// this section does not make much sense to me,
// but I will leave it intact as this is how it was in the original example I found on internet:
ks.load( null, keypass.toCharArray());
ks.store( new FileOutputStream ( "mykeystore" ), keypass.toCharArray());
ks.load( new FileInputStream ( "mykeystore" ), keypass.toCharArray());
// end of section..
// read the key file from disk and create a PrivateKey
FileInputStream fis = new FileInputStream("pkey.der");
DataInputStream dis = new DataInputStream(fis);
byte[] bytes = new byte[dis.available()];
dis.readFully(bytes);
ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
byte[] key = new byte[bais.available()];
KeyFactory kf = KeyFactory.getInstance("RSA");
bais.read(key, 0, bais.available());
bais.close();
PKCS8EncodedKeySpec keysp = new PKCS8EncodedKeySpec ( key );
PrivateKey ff = kf.generatePrivate (keysp);
// read the certificates from the files and load them into the key store:
Collection col_crt1 = CertificateFactory.getInstance("X509").generateCertificates(new FileInputStream("cert1.pem"));
Collection col_crt2 = CertificateFactory.getInstance("X509").generateCertificates(new FileInputStream("cert2.pem"));
Certificate crt1 = (Certificate) col_crt1.iterator().next();
Certificate crt2 = (Certificate) col_crt2.iterator().next();
Certificate[] chain = new Certificate[] { crt1, crt2 };
String alias1 = ((X509Certificate) crt1).getSubjectX500Principal().getName();
String alias2 = ((X509Certificate) crt2).getSubjectX500Principal().getName();
ks.setCertificateEntry(alias1, crt1);
ks.setCertificateEntry(alias2, crt2);
// store the private key
ks.setKeyEntry(defaultalias, ff, keypass.toCharArray(), chain );
// save the key store to a file
ks.store(new FileOutputStream ( "mykeystore" ),keypass.toCharArray());
(可选)验证新密钥存储库的内容:
keytool -list -keystore mykeystore -storepass password
密钥库类型:JKS密钥库提供者:SUN
您的密钥存储库包含3个条目
cn =…,ou =…,o = . .， 2014年9月2日，trustedCertEntry，证书
fingerprint (SHA1): 2C:B8:…
importkey, 2014年9月2日，PrivateKeyEntry，证书指纹
(sha1): 9c: b0:…
cn =…,o =…， 2014年9月2日，trustedCertEntry，证书指纹
(sha1): 83:63:…
(可选)在SSL服务器上测试新密钥库中的证书和私钥:
(你可能想把调试作为一个虚拟机选项:-Djavax.net.debug=all)
char[] passw = "password".toCharArray();
KeyStore ks = KeyStore.getInstance("JKS", "SUN");
ks.load(new FileInputStream ( "mykeystore" ), passw );
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
kmf.init(ks, passw);
TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(ks);
TrustManager[] tm = tmf.getTrustManagers();
SSLContext sclx = SSLContext.getInstance("TLS");
sclx.init( kmf.getKeyManagers(), tm, null);
SSLSocketFactory factory = sclx.getSocketFactory();
SSLSocket socket = (SSLSocket) factory.createSocket( "192.168.1.111", 443 );
socket.startHandshake();
//if no exceptions are thrown in the startHandshake method, then everything is fine..
最后注册你的证书与HttpsURLConnection如果计划使用它:
char[] passw = "password".toCharArray();
KeyStore ks = KeyStore.getInstance("JKS", "SUN");
ks.load(new FileInputStream ( "mykeystore" ), passw );
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
kmf.init(ks, passw);
TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(ks);
TrustManager[] tm = tmf.getTrustManagers();
SSLContext sclx = SSLContext.getInstance("TLS");
sclx.init( kmf.getKeyManagers(), tm, null);
HostnameVerifier hv = new HostnameVerifier()
{
public boolean verify(String urlHostName, SSLSession session)
{
if (!urlHostName.equalsIgnoreCase(session.getPeerHost()))
{
System.out.println("Warning: URL host '" + urlHostName + "' is different to SSLSession host '" + session.getPeerHost() + "'.");
}
return true;
}
};
HttpsURLConnection.setDefaultSSLSocketFactory( sclx.getSocketFactory() );
HttpsURLConnection.setDefaultHostnameVerifier(hv);
