Need to find X in SHA1[(AES-128(X)] DramaticTical Junior Member Posts: 7 Threads: 1 Joined: Dec 2014 12-30-2014, 04:13 PM (This post was last modified: 12-30-2014, 04:19 PM by DramaticTical.) Hi This is the problem I am trying to solve: Please take you birthday (day and month) in hexadecimal form. Find message X that SHA1[(AES-128(X)]=0x[18 arbitrary bytes][day][month]. AES key is 0x00000000000000000000000000000000. For example, if you birthday is January 10th, please find X, that SHA1[AES-128(X))]=0x[18 arbitrary bytes]1001. I am quite noob to working with problems like this so I was hoping someone could explain how exactly am I supposed to work this out. Sorry for the vague question but I don't really know what to exactly ask either. Thanks! « Next Oldest | Next Newest »
