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.
Most seals have always given a single impression on an essentially flat surface, but in medieval Europe two-sided seals with two matrices were often used by institutions or rulers (such as towns, bishops and kings) to make two-sided or fully three-dimensional impressions in wax, with a "tag", a piece of ribbon or strip of parchment, running through them. These "pendent" seal impressions dangled below the documents they authenticated, to which the attachment tag was sewn or otherwise attached (single-sided seals were treated in the same way).
Some jurisdictions consider rubber stamps or specified signature-accompanying words such as "seal" or "L.S." (abbreviation of locus sigilli, "place of the seal") to be the legal equivalent of, i.e., an equally effective substitute for, a seal.
In the United States, the word "seal" is sometimes assigned to a facsimile of the seal design (in monochrome or color), which may be used in a variety of contexts including architectural settings, on flags, or on official letterheads. Thus, for example, the Great Seal of the United States, among other uses, appears on the reverse of the one-dollar bill; and several of the seals of the U.S. states appear on their respective state flags. In Europe, although coats of arms and heraldic badges may well feature in such contexts as well as on seals, the seal design in its entirety rarely appears as an emblem.
The study of seals is known as sigillography or sphragistics.
In cryptography, SEAL (Software-Optimized Encryption Algorithm) is a very fast stream cipher optimised for machines with a 32- bit word size and plenty of RAM. SEAL is actually a pseudorandom function family in that it can easily generate arbitrary portions of the keystream without having to start from the beginning. This makes it particularly well suited for applications like encrypting hard drives.
The first version was published by Phillip Rogaway and Don Coppersmith in 1994. The current version, published in 1997, is 3.0. SEAL, covered by two patents in the United States, both of which are assigned to IBM.
A mechanical seal is a device that helps join systems or mechanisms together by preventing leakage (e.g. in a plumbing system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets.
A stationary seal may also be referred to as 'packing'.

Seal (East Asia)
A seal, in an East Asian context, is a general name for printing stamps and impressions thereof which are used in lieu of signatures in personal documents, office paperwork, contracts, art, or any item requiring acknowledgement or authorship. China, Japan, Taiwan, and Korea currently use a mixture of seals and hand signatures, and increasingly, electronic signatures. It is used to a lesser extent in Vietnam by authorised organisations and businesses, and also traditional Vietnamese artists. It was more common in Vietnam prior to French rule, when thereafter the practice of signature became a commonality, although western-like signatures are usually seen as having less authority in a company situation.
Chinese seals are typically made of stone, sometimes of metals, wood, bamboo, plastic, or ivory, and are typically used with red ink or cinnabar paste . The word 印 ("yìn" in Mandarin, "in" in Japanese and Korean, pronounced the same) specifically refers to the imprint created by the seal, as well as appearing in combination with other ideographs in words related to any printing, as in the word "印刷", "printing", pronounced "yìnshuā" in Mandarin, "insatsu" in Japanese. The colloquial name chop, when referring to these kinds of seals, was adapted from the Hindi word chapa and from the Malay word cap meaning stamp or rubber stamps.
Seal (1991 album)
Seal is the eponymous debut studio album by Seal, released in 1991. It contains the UK singles " Killer" (originally performed with Adamski), " Crazy", " Future Love Paradise", "The Beginning" and "Violet". The album debuted at #1 in the UK. Seal's following album, released in 1994, was also named Seal it is usually referred to as Seal II.
The song "Crazy" was covered by Me First and the Gimme Gimmes on their album Take a Break, by Mushroomhead on their album XIII, by Talisman on their 1995 album Life, by Alanis Morissette on her 2005 compilation album Alanis Morissette: The Collection, and by German power metal band Iron Savior.
Many of the songs (including various ZTT mixes) were featured in the Greg Stump 1991 film Groove Requiem in the Key of Ski. Later Seal tracks appeared in other Stump films as well.
The track "Killer" was also featured on the American crime series Homicide: Life on the Streets and was included on the 2-disc soundtrack album.
There are two versions of the album, with minor and major differences in three songs. The shorter version of "Wild" is more rock-based and heavy than the original. The shorter version of "Violet" contains no dialogue within the singing. Track lengths of both versions are given for each song affected.
The album won Best British Album at the 1992 Brit Awards.
Seal (contract law)
In the law, a seal affixed to a contract or other legal instrument has had special legal significance at various times in the jurisdictions that recognise it. In the courts of common law jurisdictions, a contract which was sealed ("made under seal") was treated differently from other written contracts (which were "made under hand"), although this practice gradually fell out of favour in most of these jurisdictions in the 19th and early 20th century. The legal term seal arises from the wax seal used throughout history for authentication (among other purposes).
Originally, only a wax seal was accepted as a seal by the courts, but by the 19th century many jurisdictions had relaxed the definition to include an impression in the paper on which the instrument was printed, an embossed paper wafer affixed to an instrument, a scroll made with a pen, or the printed words "Seal" or "L.S." (standing for the Latin term locus sigilli meaning "place of the seal").
Notwithstanding their reduced significance, seals are still used on contracts, usually in the impression on paper form.

Douglas Harper's Etymology Dictionary
"design stamped on wax," especially one attached to a document as evidence of authenticity, c.1200, from Old French seel "seal on a letter" (Modern French sceau), from Vulgar Latin *sigellum (source of Italian suggello, Spanish sello; also Old Frisian and Middle High German sigel, German Siegel), from Latin sigillum "small picture, engraved figure, seal," diminutive of signum "mark, token" (see sign (n.)). An earlier borrowing directly from Latin is represented by Old English insigel. Technical use, "what prevents the escape of a gas or liquid" is from 1853.
fish-eating mammal with flippers, Old English seolh "seal," from Proto-Germanic *selkhaz (compare Old Norse selr, Swedish sjöl, Danish sæl, Middle Low German sel, Middle Dutch seel, Old High German selah), of unknown origin, perhaps a borrowing from Finnic. Seal point "dark brown marking on a Siamese cat" is recorded from 1934, from the dark brown color of seal fur; compare seal brown "rich, dark brown color," by 1875. Old English seolhbæð, literally "seal's bath," was an Anglo-Saxon kenning for "the sea."
"to fasten with (or as with) a seal," c.1200, from seal (n.1). Meaning "to place a seal on (a document)" is recorded from mid-14c.; hence "to conclude, ratify, render official" (late 15c.). Sense of "to close up with wax, lead, cement, etc." is attested from 1660s, from the notion of wax seals on envelopes. In reference to the actions of wood-coatings, 1940. Related: Sealed; sealing. Sealing-wax is attested from c.1300. To seal (one's) fate (1799) probably reflects the notion of a seal on an execution warrant.
