我在使用KeyStore时遇到了一些问题。我在KeyStore上添加了密钥,无法从那里获取密钥。 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));
}
输出是:
true
false
似乎是关键的消失,或者我无法核心地加载KeyStore。你在这看到任何错误吗?
答案 0 :(得分:3)
在向其添加密钥之前,您正在保存密钥库。交换这两行:
NSMutableArray *coordinateLatit=[[NSMutableArray alloc]init];
for(NSDictionary *d in nearbyStop)
{
NSString *latit=d[@"result"][@"lat"];
if(lat) [coordinateLatit addObject:latit];
}
这样他们就是:
ks.store(new FileOutputStream(path), pass);
ks.setKeyEntry(keyName, key, pass, null);
