In cryptography, a substitution cipher is a method of encrypting in which units of plaintext are replaced with the ciphertext, in a defined manner, with the help of a key; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth.
SocialDocs file encryption uses AES256 to provide a free-online file encryption tool XFire uses AES-128, AES-192 and AES 256 to encrypt usernames and passwords Certain games and engines, such as the Rockstar Advanced Game Engine used in Grand Theft Auto IV , use AES to encrypt game assets in order to deter hacking in multiplayer.
Password-based cryptography is the study of password-based key encryption, decryption, and authorization. It generally refers two distinct classes of methods: It generally refers two distinct classes of methods:
The following example demonstrates the process of encrypting a message using the K2 Aristocrat Cipher, employing the keyword "jumping" and the phrase "The quick brown fox jumps over the lazy dog." This particular phrase is often used in cryptographic examples because it is a pangram. This makes it ideal for demonstrating encryption and ...
Lua 1.0 was designed in such a way that its object constructors, being then slightly different from the current light and flexible style, incorporated the data-description syntax of SOL (hence the name Lua: Sol meaning "Sun" in Portuguese, and Lua meaning "Moon").
Passwords or passphrases created by humans are often short or predictable enough to allow password cracking, and key stretching is intended to make such attacks more difficult by complicating a basic step of trying a single password candidate. Key stretching also improves security in some real-world applications where the key length has been ...
Encrypt the data you send: Private Wifi uses premium-level security to encrypt everything you send and receive on your computer or mobile device over public WiFi. Real-time data protection: DataMask by AOL creates a secure browsing experience by using anti-keylogging and anti-phishing software that helps protect you from internet threats and ...
In cryptography, the ElGamal encryption system is an asymmetric key encryption algorithm for public-key cryptography which is based on the Diffie–Hellman key exchange. It was described by Taher Elgamal in 1985. [ 1 ]
