我在KeyStore上有一些问题。我向KeyStore添加了密钥,但无法从那里获取它。
我的代码:
try
{
KeyGenerator keygen = KeyGenerator.getInstance("AES");
SecureRandom random = new SecureRandom();
keygen.init(128, random);
SecretKey key = keygen.generateKey();
KeyStore ks = KeyStore.getInstance("UBER", "BC");
ks.load(null, pass);
ks.store(new FileOutputStream(path), pass);
ks.setKeyEntry(keyName, key, pass, null);
System.out.println(ks.containsAlias(keyName));
key = null;
KeyStore ks1 = KeyStore.getInstance("UBER", "BC");
ks1.load(new FileInputStream(path), pass);
System.out.println(ks1.containsAlias(keyName));
}
输出为:
true
false
好像是密钥分配器,或者我不能完全加载KeyStore。在这里看到错误了吗?
最佳答案
您要在添加密钥库之前保存密钥库。交换这两行:
ks.store(new FileOutputStream(path), pass);
ks.setKeyEntry(keyName, key, pass, null);
因此它们是:
ks.setKeyEntry(keyName, key, pass, null);
ks.store(new FileOutputStream(path), pass);
