我试图在java中实现以下代码:

var keyGenerator = new Rfc2898DeriveBytes(password, salt, 1000);
byte[] key = keyGenerator.GetBytes(32);
byte[] iv = keyGenerator.GetBytes(16);
using (AesManaged aes = new AesManaged())
{
    using (ICryptoTransform encryptor = aes.CreateEncryptor(key, iv)) 
    {
        byte[] result = encryptor.TransformFinalBlock(content, 0, content.Length);
    }
}

使用以下一个:

SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
PBEKeySpec keyspec = new PBEKeySpec(password, salt, 1000, 256);
Key key = factory.generateSecret(keyspec);
SecretKeySpec secret = new SecretKeySpec(key.getEncoded(), "AES");
byte[] iv = "how_to_generate_in_java_as_in_c".getBytes();
AlgorithmParameterSpec ivSpec = new IvParameterSpec(iv);
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
cipher.init(Cipher.ENCRYPT_MODE, secret, ivSpec);
byte[] result = …
