如果知道 明文 密文 可以根据TEA算法来推算出正确的 TEA算法密钥 吗?
觉得好的请+热心, +吾爱币

下点官方手册，就能破了吗。
不是的,还得看软件作者怎么验证! 不知道算法密钥 是不能复制一模一样的狗的,但是可以根据程序验证狗的代码 提供符合条件的数据或者自己重新 写空狗来满足程序简单的验证 13407720031 发表于 2016-4-26 20:43
问下这个代码该怎么使用呢？小白一个请赐教。
提供加密解密的函数，只要有密钥就能加解密 感谢. 先留着备份,加密狗很久没玩过了 也许用的上. 感谢分享 下点官方手册，就能破了吗。 感谢分享...学习一下... Sound 发表于 2015-12-27 05:15
