Projects / crackxls2003


crackxls2003 breaks the encryption on Microsoft Excel and Word 97/2000/XP/2002/2003 files which have been encrypted using the RC4 method. These files are encrypted using a 40-bit-long key. It will not work on files encrypted using versions later than 2007 or versions 95 or earlier, or if a non-default encryption method was used.
