密码学java中如何将字符串转换为密钥

Question

我想将字符串强制转换为键类型

BufferedReader br = new BufferedReader(new FileReader(publicKeyFile));
String publicKey = br.readLine();//(Key) keyIn.readObject();
br.close();

Cipher cipher = Cipher.getInstance("RSA");
cipher.init(Cipher.WRAP_MODE, publicKey);

cipher.init(Cipher.WRAP_MODE, publicKey);需要具有接口^{}的类型的publickey

那个么我如何将字符串转换为键呢

Answer 1

使用KeyFactory根据KeySpec创建所需的密钥
