Hasty Pudding Cipher
The Hasty Pudding cipher (HPC) is a variable-block-size block cipher designed by Richard Schroeppel, which was an unsuccessful candidate in the competition for selecting the U.S. Advanced Encryption Standard (AES). It has a number of unusual properties for a block cipher: its input block size and key length are variable, and it includes an additional input parameter called the "spice" for use as a secondary, non-secret key. The Hasty Pudding cipher was the only AES candidate designed exclusively by U.S. cryptographers. The Hasty Pudding cipher is in the public domain. The cipher The Hasty Pudding cipher consists of 5 different sub-ciphers: The Hasty Pudding cipher algorithms all use 64-bit words internally. The cipher is designed to run on 64-bit machines, which can easily perform simple operations on 64-bit words. Key expansion The Hasty Pudding cipher can take a key of any number of bits for any one of the five subciphers. The cipher itself uses a '' key table'' of 1 ...

Richard Schroeppel
Richard C. Schroeppel (born 1948) is an American mathematician born in Illinois. His research has included magic squares, elliptic curves, and cryptography. In 1964, Schroeppel won first place in the United States among over 225,000 high school students in the Annual High School Mathematics Examination, a contest sponsored by the Mathematical Association of America and the Society of Actuaries. In both 1966 and 1967, Schroeppel scored among the top 5 in the U.S. in the William Lowell Putnam Mathematical Competition. In 1973 he discovered that there are 275,305,224 normal magic squares of order 5. In 1998–1999 he designed the Hasty Pudding Cipher, which was a candidate for the Advanced Encryption Standard, and he is one of the designers of the SANDstorm hash, a submission to the NIST SHA-3 competition. Among other contributions, Schroeppel was the first to recognize the sub-exponential running time of certain integer factoring algorithms. While not entirely rigorous, his ...

Niels Ferguson
Niels T. Ferguson (born 10 December 1965, Eindhoven) is a Dutch cryptographer and consultant who currently works for Microsoft. He has worked with others, including Bruce Schneier, designing cryptographic algorithms, testing algorithms and protocols, and writing papers and books. Among the designs Ferguson has contributed to is the AES finalist block cipher algorithm Twofish as well as the stream cipher Helix and the Skein hash function. In 1999, Niels Ferguson, together with Bruce Schneier and John Kelsey, developed the Yarrow algorithm, a Cryptographically-Secure Pseudorandom Number Generator (CSPRNG). Yarrow was later further developed by Niels Ferguson and Bruce Schneier into the Fortuna CSPRNG In 2001, he claimed to have broken the HDCP system that is incorporated into HD DVD and Blu-ray Disc The Blu-ray Disc (BD), often known simply as Blu-ray, is a digital optical disc data storage format.

Dom Pérignon (wine)
Dom Pérignon (; ) is a brand of vintage Champagne. It is named after Dom Pérignon, a Benedictine monk who was an important quality pioneer for Champagne wine but who, contrary to popular myths, did not discover the Champagne method for making sparkling wines.D. & P. Kladstrup ''Champagne'', p. 38 Harper Collins Publisher, History Dom Pérignon (1638–1715) was a monk and cellar master at the Benedictine abbey in Hautvillers. He pioneered a number of winemaking techniques around 1670—being the first to blend grapes in such a way as to improve the quality of wines, balance one element with another in order to make a better whole, and deal with a number of their imperfections; perfecting the art of producing clear white wines from black grapes by clever manipulation of the presses; enhancing the tendency of Champagne wines to retain their natural sugar in order to naturally induce secondary fermentation in the spring; being a master at deciding when to bottle these wines in ...
