Part 5. How Secure Is Microsoft Office's Password Protection

The Microsoft Office suite has password encryption tools. Any protection system that encrypts information is highly secure. Encrypting a file consists of dividing the file into tiny segments. Each segment is assigned an identifying number known as "Hash" and, subsequently, the password that the user enters as part of a formula designed to create chaos in the order of the segments that make up the file is used. For this reason, the only way to break this type of security is to try different combinations in an orderly manner. This process is very impractical because, with current computing power, it could take many years to crack the password (the more characters the password has, the exponentially more difficult it will be to break).
