Whirlpool

A whirlpool is a body of swirling water produced by the meeting of opposing currents. The vast majority of whirlpools are not very powerful. More powerful ones in seas or oceans may be termed maelstroms. Vortex is the proper term for any whirlpool that has a downdraft.

Very small whirlpools can easily be seen when a bath or a sink is draining. In oceans, whirlpools are normally caused by tides; there are few stories of large ships ever being sucked into such a maelstrom, although smaller craft are in danger. Smaller whirlpools also appear at the base of many waterfalls. In the case of powerful waterfalls, like Niagara Falls, these whirlpools can be quite strong. The most powerful whirlpools are created in narrow, shallow straits with fast flowing water.

Notable whirlpools

Moskstraumen

The original Maelstrom (described by Poe and others) is the Moskstraumen, a powerful tidal current in the Lofoten Islands off the Norwegian coast. The Maelstrom is formed by the conjunction of the strong currents that cross the straits (Moskenstraumen) between the islands and the great amplitude of the tides, and reaches speeds of 27.8 km/h (17.3 mph)

Whirlpool (cryptography)

In computer science and cryptography, Whirlpool (sometimes styled WHIRLPOOL) is a cryptographic hash function. It was designed by Vincent Rijmen (co-creator of the Advanced Encryption Standard) and Paulo S. L. M. Barreto, who first described it in 2000. The hash has been recommended by the NESSIE project. It has also been adopted by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) as part of the joint ISO/IEC 10118-3 international standard.

Design features

Whirlpool is a hash designed after the Square block cipher. Whirlpool is a Miyaguchi-Preneel construction based on a substantially modified Advanced Encryption Standard (AES). It takes a message of any length less than 2²⁵⁶ bits and returns a 512-bit message digest.

The authors have declared that "WHIRLPOOL is not (and will never be) patented. It may be used free of charge for any purpose."

Version changes

The original Whirlpool will be called Whirlpool-0, the first revision of Whirlpool will be called Whirlpool-T and the latest version will be called Whirlpool in the following test vectors.

Whirlpool (1934 film)

Seal IV

Seal IV is the fourth studio album (and third self-titled album) by Seal. It follows the aborted sessions for Togetherland, which was scrapped because Seal thought it was not up to the standard of his previous work.

In the United Kingdom, the album debuted at number four. In the United States, it debuted at number three in the U.S. Billboard 200, making his highest charting album to date. The album sold over 1 million copies worldwide.

Seal (emblem)

A seal is a device for making an impression in wax, clay, paper, or some other medium, including an embossment on paper, and is also the impression thus made. The original purpose was to authenticate a document, a wrapper for one such as a modern envelope, or the cover of a container or package holding valuables or other objects.

The seal-making device is also referred to as the seal matrix or die; the imprint it creates as the seal impression (or, more rarely, the sealing). If the impression is made purely as a relief resulting from the greater pressure on the paper where the high parts of the matrix touch, the seal is known as a dry seal; in other cases ink or another liquid or liquefied medium is used, in another color than the paper.

In most traditional forms of dry seal the design on the seal matrix is in intaglio (cut below the flat surface) and therefore the design on the impressions made is in relief (raised above the surface). The design on the impression will reverse (be a mirror-image of) that of the matrix, which is especially important when script is included in the design, as it very often is. This will not be the case if paper is embossed from behind, where the matrix and impression read the same way, and both matrix and impression are in relief. However engraved gems were often carved in relief, called cameo in this context, giving a "counter-relief" or intaglio impression when used as seals. The process is essentially that of a mould.
