Moreover, since the CSPs are not active by the default, their use is limited to advanced users only.

Nonetheless, a password can be fairly quickly picked with brute-force attack, because its speed is still high regardless of the CSP selected. If a strong CSP is chosen, guaranteed document decryption becomes unavailable, and therefore a password can't be removed from the document. Word's 2003/XP default protection remained the same but an option that allowed advanced users choosing a Cryptographic Service Provider was added. Statistically, the possibility of recovering the password depends on the password strength. Use of rainbow tables by online services like can not only remove a password, but also find an actual password that was used by a user to encrypt the document using brute-force attack approach.

However, modern cracking software allows removing such a password very quickly - a persistent cracking process takes one week at most. Key length in Word was strengthened up to 40 bit.
Word 95 and all the preceding editions had the weakest protection that utilized a conversion of a password to a 16-bit key. Password to open a document offers much tougher protection that had been steadily enhanced in the subsequent editions of Microsoft Office. There's no encryption of documents that are protected by such passwords, and Microsoft Office protection system saves a hash sum of a password in a document's header where it can be easily accessed and removed by the specialized software or online services like. The second and the third type of passwords were developed by Microsoft for convenient shared use of documents rather than for their protection.
It is especially vulnerable when the beginning of the output keystream is not discarded, or nonrandom or related keys are used some ways of using RC4 can lead to very insecure cryptosystems such as WEP. While remarkable for its simplicity and speed in software, RC4 has weaknesses that argue against its use in new systems. It is also knows as ARC4 or ARCFOUR and is the most widely used software stream cipher and is used in popular protocols such as Secure Sockets Layer (SSL) (to protect Internet traffic) and WEP (to secure wireless networks). This encryption method is also found in older Microsoft Office suits like Offand even 2003. Microsoft Office Word utilizes the encryption algorithm knows as RC4.
