The symbol # is known variously in English-speaking regions as the number sign, [1] hash, [2] or pound sign. [3] The symbol has historically been used for a wide range of purposes including the designation of an ordinal number and as a ligatured abbreviation for pounds avoirdupois – having been derived from the now-rare ℔.

Hash key may refer to: Number sign , also known as the number, pound or hash key, a key on a telephone keypad For its use in data structure, database and cryptographic applications, see hash function or unique key
Hash-based signature schemes use one-time signature schemes as their building block. A given one-time signing key can only be used to sign a single message securely. Indeed, signatures reveal part of the signing key. The security of (hash-based) one-time signature schemes relies exclusively on the security of an underlying hash function.
Key word signing is a form of augmentative and alternative communication (AAC) that uses manual signing as an additional mode of communication with the intention of strengthening the message. [2] Research suggests that lexical representations of words, including manual signing, as well as speech and graphic symbols, can be used to reinforce ...
1 Control-C has typically been used as a "break" or "interrupt" key. 2 Control-D has been used to signal "end of file" for text typed in at the terminal on Unix / Linux systems. Windows, DOS, and older minicomputers used Control-Z for this purpose.
The traditional key pair is based on a modulus, n, that is the product of two distinct large prime numbers, p and q, such that =. Starting with version 2.1, this definition was generalized to allow for multi-prime keys, where the number of distinct primes may be two or more.
The Secure Hash Algorithms are a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST) as a U.S. Federal Information Processing Standard (FIPS), including: SHA-0: A retronym applied to the original version of the 160-bit hash function published in 1993 under the name "SHA". It was ...
