A free and open source command-line tool for easily cracking encrypted XLS files
The application will try to crack the XLS file and present a working key if it finds one. It doesn't work on files encrypted using Excel or Word 2007 or later. Additionally, it will not work with files that were encrypted with a non-standard method.
To use the program, simply execute ./crackxls2003 [filename.xls]. To restart the cracking process, use ./crackxls2003 -s "00 00 00 00 00" file.xls.
Users are advised that the program is extremely slow, as on some computers will take even a month to check through the whole key-space and decrypt the files.
