However, generally they are considerably slower (typically by a factor 2–10) than fast, non-cryptographic random number generators. These include: Stream ciphers. Popular choices are Salsa20 or ChaCha (often with the number of rounds reduced to 8 for speed), ISAAC, HC-128 and RC4. Block ciphers in counter mode.
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] Another type of approach is password spraying, which ...
The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. [5] [6] [7] The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; [8] the pattern of position detection was found and determined by applying the least-used ratio (1:1:3 ...
It also revealed its Mini Apps feature, which allows users to build apps within Telegram, in a bid to become increasingly like the super app WeChat, which boasts over 1.3 billion mostly Chinese users.

A cryptographically secure pseudorandom number generator ( CSPRNG) or cryptographic pseudorandom number generator ( CPRNG) is a pseudorandom number generator (PRNG) with properties that make it suitable for use in cryptography. It is also referred to as a cryptographic random number generator ( CRNG ).
A technetium-99m generator, or colloquially a technetium cow or moly cow, is a device used to extract the metastable isotope 99m Tc of technetium from a decaying sample of molybdenum-99. 99 Mo has a half-life of 66 hours [1] and can be easily transported over long distances to hospitals where its decay product technetium-99m (with a half-life ...
A 2015 Williams Institute comparison of 50 Most Populous Metro Areas ranked by Gallup Daily tracking and the US Census, ranked SLC 7th in Metro areas, up from 39th in 1990. [ 148 ] In 2007, Salt Lake City was ranked by Forbes as the most vain city in America, based on the number of plastic surgeons per 100,000 and their spending habits on ...
