在Storm中實現(xiàn)數(shù)據(jù)的加密和解密可以通過使用加密算法和解密算法對數(shù)據(jù)進(jìn)行處理。以下是一種可能的實現(xiàn)方式:
import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.spec.SecretKeySpec;
public class EncryptionUtil {
private static final String ALGORITHM = "AES";
private static final String KEY = "YourSecretKey";
public static byte[] encrypt(byte[] data) {
try {
SecretKey secretKey = new SecretKeySpec(KEY.getBytes(), ALGORITHM);
Cipher cipher = Cipher.getInstance(ALGORITHM);
cipher.init(Cipher.ENCRYPT_MODE, secretKey);
return cipher.doFinal(data);
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
}
public class DecryptionUtil {
private static final String ALGORITHM = "AES";
private static final String KEY = "YourSecretKey";
public static byte[] decrypt(byte[] encryptedData) {
try {
SecretKey secretKey = new SecretKeySpec(KEY.getBytes(), ALGORITHM);
Cipher cipher = Cipher.getInstance(ALGORITHM);
cipher.init(Cipher.DECRYPT_MODE, secretKey);
return cipher.doFinal(encryptedData);
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
}
在Storm拓?fù)渲?,可以在需要加密或解密?shù)據(jù)的地方調(diào)用相應(yīng)的加密和解密方法,對數(shù)據(jù)進(jìn)行處理。例如,在Spout或Bolt中處理數(shù)據(jù)前先加密,處理完成后再解密。
