我想创建一个将.cer CA导入现有密钥库文件的JAVA程序。这样最终用户可以更加方便地插入CA证书(无需使用CMD和命令中的键)。
JAVA代码可以在任何地方做到这一点吗?
我尝试以某种方式,但仍然无法将证书导入Java
CertificateFactory cf = CertificateFactory.getInstance("X.509");
InputStream certstream = fullStream (certfile);
Certificate certs = cf.generateCertificates(certstream);
错误是不兼容的类型,还有其他建议吗?
谢谢很多
以下代码yourcert.cer
无需使用即可将CA cert文件插入密钥库keytool
:
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.security.Key;
import java.security.KeyStore;
import java.security.cert.Certificate;
import java.io.IOException;
import java.io.InputStream;
import java.io.DataInputStream;
import java.io.ByteArrayInputStream;
import java.security.spec.*;
import java.security.cert.Certificate;
import java.security.cert.CertificateFactory;
import java.util.Collection;
public class ImportCA {
public static void main(String[] argv) throws Exception {
String certfile = "yourcert.cer"; /*your cert path*/
FileInputStream is = new FileInputStream("yourKeyStore.keystore");
KeyStore keystore = KeyStore.getInstance(KeyStore.getDefaultType());
keystore.load(is, "yourKeyStorePass".toCharArray());
String alias = "youralias";
char[] password = "yourKeyStorePass".toCharArray();
//////
CertificateFactory cf = CertificateFactory.getInstance("X.509");
InputStream certstream = fullStream (certfile);
Certificate certs = cf.generateCertificate(certstream);
///
File keystoreFile = new File("yourKeyStorePass.keystore");
// Load the keystore contents
FileInputStream in = new FileInputStream(keystoreFile);
keystore.load(in, password);
in.close();
// Add the certificate
keystore.setCertificateEntry(alias, certs);
// Save the new keystore contents
FileOutputStream out = new FileOutputStream(keystoreFile);
keystore.store(out, password);
out.close();
}
private static InputStream fullStream ( String fname ) throws IOException {
FileInputStream fis = new FileInputStream(fname);
DataInputStream dis = new DataInputStream(fis);
byte[] bytes = new byte[dis.available()];
dis.readFully(bytes);
ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
return bais;
}
}
