Ophcrack is a free open-source (GPL licensed) program that cracks Windows log-in passwords by using LM hashes through rainbow tables.The program includes the ability to import the hashes from a variety of formats, including dumping directly from the SAM files of Windows, and can be run via the command line or using the program’s GUI (Graphical user interface).

In cryptanalysis and computer security, password cracking is the process of guessing passwords [1] protecting a computer system.A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. [2]
Sequence diagram for a Wi‑Fi deauthentication attack. Unlike most radio jammers, deauthentication acts in a unique way.The IEEE 802.11 (Wi-Fi) protocol contains the provision for a deauthentication frame.
On systems or services using NTLM authentication, users' passwords are never sent in cleartext over the wire. Instead, they are provided to the requesting system, like a domain controller, as a hash in a response to a challenge–response authentication scheme.
A dictionary attack is based on trying all the strings in a pre-arranged listing. Such attacks originally used words found in a dictionary (hence the phrase dictionary attack); [2] however, now there are much larger lists available on the open Internet containing hundreds of millions of passwords recovered from past data breaches.

The PBKDF2 key derivation function has five input parameters: [9] DK = PBKDF2(PRF, Password, Salt, c, dkLen) where: PRF is a pseudorandom function of two parameters with output length hLen (e.g., a keyed HMAC)
Reconstruction of the appearance of cyclometer, a device used to break the encryption of the Enigma machine.Based on sketches in Marian Rejewski's memoirs.. Cryptanalysis (from the Greek kryptós, "hidden", and analýein, "to analyze") refers to the process of analyzing information systems in order to understand hidden aspects of the systems. [1]
