In Excel and Word 95 and prior editions a weak protection algorithm is used that converts a password to a 16-bit verifier and a 16-byte XOR obfuscation array [1] key. [4] Hacking software is now readily available to find a 16-byte key and decrypt the password-protected document. [5] Office 97, 2000, XP and 2003 use RC4 with 40 bits. [4]
When it was released, the computer press reported on the change approvingly: "PowerPoint 4.0 has been re-engineered from the ground up to resemble and work with the latest applications in Office: Word 6.0, Excel 5.0, and Access 2.0.

For example, master keyed pin tumbler locks often have two shear points at each pin position, one for the change key and one for the master key. A far more secure (and more expensive) system has two cylinders in each lock, one for the change key and one for the master key. Master keyed lock systems generally reduce overall security. [2]
It is typically used as the space for the page number. In the earliest printed books it also contained the first words of the next page; in this case they preferred to place the page number in the page header, in the top margin.
