AES256解密示例代码 下面是一个使用Java实现AES256解密的示例代码: importjavax.crypto.Cipher;importjavax.crypto.spec.SecretKeySpec;importjava.nio.charset.StandardCharsets;importjava.util.Base64;publicclassAES256Decryption{privatestaticfinalStringALGORITHM="AES";privatestaticfinalStringENCRYPTION_KEY="0123456789abc...
AES(Advanced Encryption Standard)是一种对称加密算法,它在Java中可以用于加密数据,而在C#中可以用于解密数据。 AES加密算法是目前应用最广泛的加密算法之一,它具有高安全性、高效率和可靠性的特点。AES算法支持不同的密钥长度,包括128位、192位和256位。较长的密钥长度可以提供更高的安全性,但也会增加计算成本。
