1. 导入必要的库 在Java中,我们需要通过import语句导入所需的库,以便使用AES加密算法。 importjavax.crypto.KeyGenerator;// 导入KeyGenerator库importjavax.crypto.SecretKey;// 导入SecretKey库importjava.security.NoSuchAlgorithmException;// 导入NoSuchAlgorithmException类 1. 2. 3. 这些库提供了生成密钥所需的功能。
importjavax.crypto.KeyGenerator;importjava.security.Key; 1. 2. 生成AES密钥 KeyGeneratorkeyGenerator=KeyGenerator.getInstance("AES");keyGenerator.init(128);KeysecretKey=keyGenerator.generateKey(); 1. 2. 3. 获取公钥和私钥 byte[]publicKeyBytes=secretKey.getEncoded();byte[]privateKeyBytes=secretKey.getEn...
