在实际应用中,我们可以使用Python的第三方库如pycryptodome来实现aes算法的加密和解密。下面是一个简单的Python代码示例: from Crypto.Cipher import AES from Crypto.Util.Padding import pad, unpad def encrypt_data(data, key): cipher = AES.new(key, AES.MODE_ECB) encrypted_data = cipher.encrypt(pad(dat...

if (encryptKey.length() != KEY_LENGTH) { throw new IllegalArgumentException("加密的encryptKey必须为16位"); } // 创建cipher实例 参数按"算法/模式/填充模式" "AES/ECB/PKCS5Padding" Cipher cipher = Cipher.getInstance(PADDING); // 初始化ciper, // (1)opmode :Cipher.ENCRYPT_MODE(加密模式)和...
println("Encrypted text: " + encryptedText); // 解密 Cipher decryptCipher = Cipher.getInstance("AES"); decryptCipher.init(Cipher.DECRYPT_MODE, secretKey); byte[] decryptedBytes = decryptCipher.doFinal(Base64.getDecoder().decode(encryptedText)); String decryptedText = new String(decryptedBytes)...

1. 环境配置：确保你的开发环境中已经包含了必要的加密库。例如，如果你使用的是Java，需要确保已经导入了相应的加密库或框架。在某些情况下，可能还需要配置特定的安全提供者。2. 参数理解：`cipher.getInstance`中的参数`"aes/ecb/pkcs5padding"`代表使用的加密算法、模式和填充方式。具体为：AES代表...
