History of password protection in MS-Word

In Word 95, 97 and 2000 the encryption method contains vulnerabilities. This means that the document can be decrypted within 10 seconds without knowing the password. There are password crackers that even offer online services to do this.

In Word 2002 and 2003, the default encryption method is "97/2000 compatible", which means that the same insecure encryption method is used. To achieve good encryption, one has to select a strong encryption method. . Office 2007 uses strong encryption by default. This means that the only way to break the protection of a "password to open" is to guess the password. If a strong password is used, this could take years. Microsoft Office 2007 uses 128 bit AES for password encryption.
