Cryptanalysis

Hi there, I’m struggling with the AES-ECB Flag...

Key point of AES-ECB is, that same input blocks are calculated to same output blocks. That’s why I was looking for equal blocks...

I suggest that the key length is 192 and part of the content, since the total length of the file doesn’t equal the block length.
That’s why I tried to encrypt everything with the last 192 Bit as a Key and with the first 192 Bit as Key (in latter case, I deleted the Key from the content.
Also without any result...

There are a couple of half-bytes 0x00000000, 0x10000000 and 0x20000000. That’s quite suspicious but I don’t really know how to use this information..

Can please someone give me a hint??

Thanks

Google for the filename description.
