使用密钥库创建.p12文件 [英] Creating a .p12 file with a KeyStore
本文介绍了使用密钥库创建.p12文件的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个为我创建证书的外部服务,我从中获得一个缓冲区(字符串)。我尝试将此缓冲区加载到Java中的KeyStore中,然后使用存储功能来创建.p12文件。但是,存储功能会引发异常-给最终块未正确填充。
I have an external service that creates certificate for me, out of which I recieve a buffer (String). I attempt to load this buffer into a KeyStore in Java and then use the "store" function in order to create a .p12 file. However, the store function throws an exception - "Given final block not properly padded".
无论我如何尝试,我都无法使它正常工作或找到导致此情况的原因
No matter what I try, I cannot get this to work or find the cause of the issue.
我的代码是:
public void createP12Certificate(String userName, String comment) throws KeyStoreException, AdminCertificateException, CertificateException, NoSuchAlgorithmException, IOException
{
KeyStore store = KeyStore.getInstance("PKCS12");
/* Some Code that gets 'buff' etc. */
byte[] byteBuff = hexStringToByteArray(buff);
Arrays.reverse(byteBuff);
InputStream inputStream = new ByteArrayInputStream(byteBuff);
store.load(inputStream, password.toCharArray());
OutputStream outputStream = new FileOutputStream(userName+".p12");
store.store(outputStream,anotherPassword); //Throws Exception
}
非常感谢!
推荐答案
问题出在那几行
/* Some Code that gets 'buff' etc. */
byte[] byteBuff = hexStringToByteArray(buff);
因为其他发布的代码都可以正常工作。
Because the other posted code would work without an exception.
char[] passwordChars = "password".toCharArray();
String fileOne = "/tmp/output_1.p12";
String fileTwo = "/tmp/output_2.p12";
KeyStore keyStore = KeyStore.getInstance("PKCS12");
keyStore.load(null, null);
keyStore.store(new FileOutputStream(fileOne), passwordChars);
keyStore = KeyStore.getInstance("PKCS12");
byte[] byteBuff = Files.readAllBytes(Paths.get(fileOne));
InputStream inputStream = new ByteArrayInputStream(byteBuff);
keyStore.load(inputStream, passwordChars);
keyStore.store(new FileOutputStream(fileTwo), passwordChars);
