History of Office encryption Weak encryptions. 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 key. Hacking software is now readily available to find a 16-byte key and decrypt the password-protected document.
AACS encryption key controversy. Internet users began circulating versions of this image, calling it the Free Speech Flag, in blog posts on dozens of websites and as user avatars on forums such as Digg.
