通过隐写图片工具stegsolve工具打开pic1.jpg 然后选择image comibiner工具打开另一张图片pic2.png \ 对2张图片进行合并,合并后可获得flag 方法二: 得到两张相似的图片,第一反应是两张图片的合并,于是使用kali下的compare命令进行合并,然后得到FLAG compare pic1.jpg pic2.jpg -compose src flag.jpg 最终得到flag:...

Thus we can conclude that the transforms T and T' are "Multiplicative Inverse" of each other, and since these transforms only depend on the`KEY`used during the encryption (or decryption), we need to perform the decryption with a KEY', such that KEY' = MultipicativeInverse(KEY). ...
