Diceware is a method for creating passphrases, passwords, and other cryptographic variables using ordinary dice as a hardware random number generator. It involves rolling five dice and looking up the numbers in a word list to form a word, which can be repeated to form a longer passphrase.
Learn how to use the major system, a mnemonic technique to memorize numbers by converting them into consonants and words. The system is based on the principle that images are easier to remember than numbers and has a standard mapping of numerals to sounds.
A pseudorandom number generator (PRNG) is an algorithm that produces a sequence of numbers that resemble random numbers, but are completely determined by an initial value. Learn about the properties, applications, and potential issues of PRNGs, as well as the difference between PRNGs and cryptographically secure PRNGs (CSPRNGs).
A hardware random number generator (HRNG) is a device that generates random numbers from a physical process capable of producing entropy. Learn about the history, uses, and types of HRNGs, and how they differ from pseudorandom number generators (PRNGs).
The VIC cipher can be regarded as the evolutionary pinnacle of the Nihilist cipher family.. The VIC cipher has several important integrated components, including mod 10 chain addition, a lagged Fibonacci generator (a recursive formula used to generate a sequence of pseudorandom digits), a straddling checkerboard, and a disrupted double transposition.
RNG stands for random number generator, a device or algorithm that produces a sequence of numbers or symbols that cannot be reasonably predicted. Learn about the methods, applications and types of RNG, such as true and pseudorandom numbers.
Learn how to generate strong and secure passwords using software, hardware, or manual methods. Compare different sources of randomness, password types, and entropy calculations.
ASCII (/ ˈ æ s k iː / ⓘ ASS-kee), [3]: 6 an acronym for American Standard Code for Information Interchange, is a character encoding standard for electronic communication. . ASCII codes represent text in computers, telecommunications equipment, and other devic
