Hashing can't be reversed.


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.


Difference between Internal hashing n external hashing?

Internal hashing mainly used for internal file, it is particularly an array of records. External hashing used for file disk


Which is better encryption algorithm among DES Blowfish and MD5?

MD5 isn't a encryption algorithm, it's a hashing algorithm. Encryption will 'hide' the meaning of the encrypted text, while MD5 will 'add up' all the text to come up with a number. This number can be compared to another time this file was 'added up', to provide a simple kind of check to see if the text has been changed or if it is the same.


What are the available key sizes for the SHA1 hashing algorithm?

SHA-1 produces a fixed output size of 160 bits, which is equivalent to 20 bytes. Unlike some other hashing algorithms that offer multiple key sizes, SHA-1 does not provide options for varying output lengths. Its design specifies this single, consistent size for all generated hash values.

What is the significance of ketama hashing in load balancing algorithms?

Ketama hashing is significant in load balancing algorithms because it helps evenly distribute incoming requests among servers based on a consistent hashing algorithm. This ensures that the workload is spread efficiently, preventing any single server from becoming overwhelmed.


The rules for making a hash algorithm are public on the fips website how come someone with access to lets say my sha1 function cant decipher the resulting hash?

Great question - one of the things about hashing is that it is very difficult or impossible to reverse the hashing process, even if you know the algorithm. This is because just doing the steps backwards will not result in the original value.


How does two-way hashing work to securely encrypt and decrypt data in a single process?

Two-way hashing uses a mathematical algorithm to convert data into a fixed-length string of characters, making it difficult to reverse engineer the original data. This process allows for secure encryption and decryption of data using the same algorithm, providing a way to protect sensitive information.


What are different types of hashing techniques are there in DBMS?

there are 2 types of hashing techniques 1- Static hashing 2-Dynamic hashing


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


What is the meaning of the acronym SHA1?

Secure hashing algorithm refers to a 2 layer encryption device. This a very rare term and would not be commonly know to anyone not in the computer programming field.


What are the difference between static and dynamic hashing in DBMS?

Search operation in static hashing is time consuming, but in dynamic hashing it is not.
