The_oldman Posted November 27 Share Posted November 27 I have some files which encrypted by a 256-bytes keys and I already found all these keys(256bytes) I wounder if QuickBMS can handle a lookup table to decrypt the files? eg: keys for 00 to FF(255) are 0xb2,0x11,0x34,0x3f,0x68,0x94,0xf3,0x22,0x6d....0x00,0xd3,0xff,0x58 the encrypt file is 01 02 05 05 ff fd 08 06... the real data will be 11 34 94 94 58 00 6d f3... thanks Link to comment Share on other sites More sharing options...
Solution ikskoks Posted November 27 Solution Share Posted November 27 I did something similar in the past using MEMORY_FILE's in quickbms for game "The Genius of Sappheiros" https://github.com/bartlomiejduda/Tools/blob/master/NEW Tools/The Genius of Sappheiros Weekend/The_Genius_of_Sappheiros_Weekend_PAK_script.bms Check out MAKE_KEY_ARRAY function. In your case you should probably use "goto" and "get" commands to read the data first and then you should copy data to MEMORY_FILE. Link to comment Share on other sites More sharing options...
