[[Attacks]] used against encryption. Part of the [[science]] of [[Cryptography]]. Like any [[security]] system, it is important to know what tools a [[thief]] has in order to make a stronger lock.

* [[Brute Force]] Trying all possible [[key|keys]]; a systematic [[searching|search]] to find the decryption key. This can take a prohibitively long time.

* [[Dictionary Attack]] - Trying all the words in the dictionary to guess a [[password]]. This is an effective attack as most people use simple words their password. Often, even if a dictionary attack doesn't work on one user, if an attacker has access to many 100+ users, he can likely get access to at least one using this technique.

* [[Math Attack]] - Trying to solve the math problem itself something historically, done during [http://www.saintanns.k12.ny.us/depart/math/Gena/ccw.html War time] but no longer feasible due to advances in encryption complexity. Except, however, given a theoretical leap in computing power such as with [[Quantum Computing]] or an advance in the ability to factor several multiplied prime numbers. A major eventual weakness in mathematical (whether [[Public-Key Cryptosystem|public-key]] or [[Symmetric-Key Cryptosystem|symmetric]]) cryptography that could someday be solved perhaps years or hundreds of years from now.

* [[Key-Logging Attack]] - any item or software that captures [[user]]-input such as typed-in [[password|passwords]], [[e-mail]] messages, or otherwise. This often makes cryptography useless by either gaining the encrypted document as it is typed or the password used to encrypt it.

* [[Man-In-The-Middle Attack]] - someone between you and your connection works as a intermediary, listening in on your communications and possibly [[modify|modifying]] them.

* [[Rubber Hose Attack]] - referring to the human vulnerability via social, litigation, or physical, stress, that people will reveal the method to access hidden information.

* [[Traffic Analysis Attack]] - in the absence of a way to decipher a given method of encryption, a method to see what ''type'' of information is being transferred therefore infer what is being communicated ([[chat]], [[e-mail]], [[data]]).

* [[Undelete Attack]] - finding deleted but still-present files on a computer.
