要将AES CTR模式追加到CipherOutputStream中,您可以按照以下步骤操作:
以下是一个示例代码,演示了如何追加AES CTR模式到CipherOutputStream中:
import javax.crypto.Cipher;
import javax.crypto.CipherOutputStream;
import javax.crypto.spec.SecretKeySpec;
import java.io.FileOutputStream;
import java.io.IOException;
public class AESCTR {
public static void main(String[] args) {
try {
// 定义密钥和数据
byte[] key = "0123456789abcdef".getBytes();
byte[] data = "Hello, World!".getBytes();
// 创建Cipher对象并初始化为AES CTR模式
Cipher cipher = Cipher.getInstance("AES/CTR/NoPadding");
SecretKeySpec secretKeySpec = new SecretKeySpec(key, "AES");
cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec);
// 创建输出流和CipherOutputStream
FileOutputStream fileOutputStream = new FileOutputStream("encrypted.txt", true);
CipherOutputStream cipherOutputStream = new CipherOutputStream(fileOutputStream, cipher);
// 写入加密数据
cipherOutputStream.write(data);
// 关闭流
cipherOutputStream.close();
fileOutputStream.close();
System.out.println("数据已加密并追加到文件中。");
} catch (Exception e) {
e.printStackTrace();
}
}
}
请注意,此示例将数据追加到名为"encrypted.txt"的文件中。每次运行该代码,它都会在文件中追加新的加密数据。
