Since version 0.86 BitComet includes discussion and stat-tracking features which send information about torrents to the Bitcomet.com servers, including the torrent hash.
Each file that is shared using eMule is hashed as a hash list comprising separate 9500 kibibyte chunks using the MD4 algorithm.
Donald Knuth notes that Hans Peter Luhn of IBM appears to have been the first to use the concept, in a memo dated January 1953, and that Robert Morris used the term in a survey paper in CACM which elevated the term from technical jargon to formal terminology.

The same technique can be used to map two-letter country codes like "us" or "za" to country names (262=676 table entries), 5-digit zip codes like 13083 to city names (100000 entries), etc.
The site itself does not host the files, but collects and sorts special Magnet links, which contain a hash value to identify files being shared by other Gnutella2 users through clients such as Shareaza.
In one form, product activation refers to a method invented by Ric Richardson and patented (US 5,490,216) by Uniloc where a software application hashes hardware serial numbers and an ID number specific to the product's license (a product key) to generate a unique installation ID.
The document, email, or file to be protected is used to generate a signed hash, a number generated from the contents of the document.
Examples of hard fingerprints are hashcode (or Hash function), for which even a one bit modification of the original content produces different fingerprint and exclude all recognition process.
If a file was found, the hash of the file along with IP address and Primary node details of the user with the file was sent to the user who made the search.

For example, MISTY1 is a Feistel cipher using a three-round Feistel network in its round function, Skipjack is a modified Feistel cipher using a Feistel network in its G permutation, and Threefish (part of Skein) is a non-Feistel block cipher that uses a Feistel-like MIX function.
These techniques included full-text processing; hash codes; Key Word in Context indexing (see also Herbert Marvin Ohlman); auto-indexing; automatic abstracting and the concept of selective dissemination of information (SDI).
Logging in involves a challenge/response protocol using the SHA-1 hash function and RC4.
When a second hash function ξ is used to determine the sign of a feature's value, the expected mean of each column in the output array becomes zero because ξ causes some collisions to cancel out.
Fowler–Noll–Vo hash function, a non-cryptographic hash function created by Glenn Fowler, Landon Curt Noll, and Phong Vo
The situation changed fundamentally in Excel 2007, where the modern AES algorithm with a key of 128 bits started being used for decryption, and a 50,000-fold use of the hash function SHA1 reduced the speed of brute-force attacks down to hundreds of passwords per second.
