Dec 10, 2010 · A hash value is a result of a calculation (hash algorithm) that can be performed on a string of text, electronic file or entire hard drives contents. The result is also referred to as a checksum, hash code or hashes.
A hash value (or simply hash), also called a message digest, is a number generated from a string of text. The hash is substantially smaller than the text itself, and is generated by a formula in such a way that it is extremely unlikely that some other text will produce the same hash value. Hash values can be thought of fingerprints of files. Compared to the authentication of ID documents, the security level of hash values is higher. Since hash is a unique computational numerical value generated according to the size, time, type and creator. In Blockchain, a hash value will be generated per transaction. Our Hash Function that will return the Hash Code will be, Hash Code = Element value % 10. This Hash code for, 12 will be 2. 23 will be 3. 56 will be 6. 67 will be 7. 89 will be 9. 43 will be 3. Now Using this hash code for each element it will be decided where that element will be stored i.e. 12 will be in bucket 2 because its hash code is 2. Hashing is the transformation of a string of character s into a usually shorter fixed-length value or key that represents the original string. Hashing is used to index and retrieve items in a database because it is faster to find the item using the shorter hashed key than to find it using the original value. It is also used in many encryption Aug 23, 2018 · Hashes are the products of cryptographic algorithms designed to produce a string of characters. Often these strings have a fixed length, regardless of the size of the input data. Take a look at the above chart and you’ll see that both “Fox” and “The red fox jumps over the blue dog” yield the same length output. Hashish, or hash, is a drug made from the resin of the cannabis plant. It is consumed by inhaling from a small piece, typically in a pipe, bong , vaporizer or joint , or via oral ingestion (after decarboxylation ). Mar 28, 2007 · A "hash value" is not particular to Oracle. Rather, it is a computer science concept. I will briefly explain this concept, but you can read more about hash values at Wikipedia. Data is often stored in an array, which is a set of consecutive chunks of memory. Oracle's caches are often predefined

Let me explain (with an example) how we can use Hash Values to determin the Integrity of Data. There are many free tools available in internet to find Hash Values of data. One of such tool is File Checksum Integrity Verifier, which is a free download from Microsoft. FCIV is a command line tool, which supports MD5 and SHA-1 Hash Value calculation.
