生成AES公钥和私钥的方法是使用Java的密钥生成器(KeyGenerator)类和密钥生成器(KeyPairGenerator)类。下面将介绍如何使用这两个类来生成AES公钥和私钥,并提供一个具体的问题来解决。 ## 问题描述 假设有两个应用程序A和B,它们需要进行加密通信。A需要生成AES公钥和私钥,并将公钥发送给B,B使用这个公钥来加密数据,然后...
AES Key Generator Please enjoy your free AES Key! Below is a Base64 Encoded AES-256 key which was been generated using the secure javax KeyGenerator. This key will work perfectly with any of the AES encryption code elsewhere on my site, and probably most of yours as well....
