What is the difference between AES Rijndael symmetric algorithm encryption and a hash algorithm?
678
Advantages of Secure hash algorithm?
because it is more secure than any other algorithm.
What is Hash file organization in DBMS?
Hashing is the most common form of purely random access to a file or database. It is also used to access columns that do not have an index as an optimisation technique. Hash functions calculate the address of the page in which the record is to be stored based on one or more fields in the record. The records in a hash file appear randomly distributed across the available space. It requires some hashing algorithm and the technique. Hashing Algorithm converts a primary key value into a record address. The most popular form of hashing is division hashing with chained overflow.
What is hash key?
hash key is an element in the hash table. it is the data that you will combine (mathematical) with hash function to produce the hash.
What is a hashing algorithm?
hashing algorithm contain two components - hashing function & collision. hashing is mechanism which generally used in random file organization to convert the record key value into address.

Which common hash algorithm is a 160 bit hash value?
Both SHA-1 and SHA-0 use a 160-bit hash value. Note that "SHA-0" is a retronym for the original SHA hash algorithm. SHA-1 corrected some significant flaws in the original algorithm that yielded some serious security weakness. The TIGER hash algorithm is designed to use a 192-bit hash, but also has the capability to use 160-bit and 128-bit hash values. The HAVAL algorithm can produce hashes in lengths of 128 bits, 160 bits, 192 bits, 224 bits, and 256 bits. One version of the RIPEMD algorithm, RIPEMD-160, has a 160-bit hash. Other versions of RIPEMD, RIPEMD-128, RIPEMD-256, and RIPEMD-320, use 128, 256, and 320-bit hashes respectively. Of these, the most common is probably SHA-1, which is available on most Windows based machines.
Which hash algorithm creates a 128-bit digest?
MD5
Which hash algorithm is commonly used in networking protocols and systems?
SHA-1
Which hash algorithm is a 160 bit hash value?
Some well-known hash algorithms with a 160-bit output:RIPEMMD-160SHA-0/SHA-1Tiger-160
Which two algorithm are used for hash encoding to guarantee the ingerity of data?
MD5 and SHA
What makes fasta faster than needleman wunsch algorithm?
Hash loookup table in FASTA makes it faster than Needleman Wunsch algorithm.
What is a mathematical formula that generates a code from the contents of a message?
hash, cypher, algorithm, private key
What does MD5 encryption mean?
You are probably referring to the MD5 Message-Digest Algorithm which is a widely used cryptographic hash function that produces 128-bit (16-byte) hash values. A hash function is an algorithm that takes a block of data and creates a string of data (hash) of fixed length. By running the algorithm on a received block of data, a user should be able to detect whether the data has been altered because a given block of data should always yield the same hash unless it has been altered. Ideally a hash function will allow easy computation of the hash value for any given message but make it hard to start with the hash value and come up with a message that will yield that hash value. It should also be so difficult to modify a message without changing the hash that the time and effort necessary to do it exceeds the value of doing it and extremely difficult or impractical to find two different messages with the same hash. Note that by its nature the MD5 hash is not supposed to allow you to recover the message that was processed. Usually when we use the word "encryption" we are talking about a process where a message is converted to something called "cyphertext" which is unreadable unless you have the right algorithm and key to decrypt it and convert it back to the original message. In this respect it is more accurate to refer to "MD5 hashing" rather than MD5 encryption. See the attached link for more details on the MD5 hash.
How does the algorithm work?
It is basically a one way cryptographic hash function. It performs many binary options on the "message" to compute and process a 128 "hash". It is a very basic form a processing binary data.
What is the definition of the word 'hashing'?
Hashing is an algorithm (hash function) to convert a string of characters into a fixed sized text using mathematical functions. The file to be hashed is known as “input” the algorithm used in known as ”hash function” and output is called “Hash Value”, some people call hash value as message digest. Hash value is the value that dictates what exactly in this file and always produces hexadecimal value. more on :networkingmania
