File Header

MS Word documents begin with the hex string 0xd0cf11e0a1b11ae1 and end with the string "Word.Document.8".


Versions 97/2000 encrypt documents with a very weak algorithm. This password scheme can be broken easily by several different products and it is possible to decrypt the contents without discovering the password. This is done by testing all 1,099,511,627,776 possible keys. Ultimate Zip Cracker by VDGSoftware is one utility that can perform this decryption.
