What is Hashing Algorithm & How Does It Work?
Hashing Algorithm – One of the Methods for Sending Essential Files
Here’s What’s Hashing
Moreover, it’s one of the convenient and secure ways when it comes to identifying or comparing databases and files. It’s the process which transforms the dataset into a fixed-length character series, without considering the size of input data. And the received output is known as hash value, digest, code, or simply hash. Additionally, the term “hash” is used for describing both the hash function as well as the hash value.
To put it another way, it’s majorly used for confirming the originality of the sent message. For example, if you send a file and you want to know whether it has been sent to an intended user without any change or not, then there’s the number of ways to check, like contacting the addressee or verifying the file and one of the approaches is also this hashing algorithm.
Let’s dig into the detail and understand: Hash Function & Hashing Algorithm.
What’s the Hash Function?
Let’s move further and explore what’s hashing algorithm.
What is Hashing Algorithm & How Hashing Algorithm Work?
However, there’s no guarantee that the message will be in multiples of 512 bits. In some cases, a technique named Padding is used, where the whole message is divided equally in a fixed size of data blocks. The below example shows how the data blocks are processed.
An Ideal Hash Cryptographic Hash Functions Are:
- Fast to compute the hash value regardless of the data.
- Once hashing is done, it’s almost impossible to generate a message in its original form.
- Should be able to avoid hash collisions. For every message, it has its hash value.
- Even a small change should make a change in the entire hash value. Also known as the avalanche effect.
Here Are Some of the Popular Hashing Algorithms:
1. MD (Message Digest) Algorithm
3. Rivest–Shamir–Adleman (RSA)
4. RACE Integrity Primitives Evaluation Message Digest (RIPEMD)
5. Secure Hash Algorithm (SHA)
Moreover, it’s also useful for the identification of the files, indexing of data in hash tables, detecting duplicate data, or as checksums to detect there’s no accidental or intentional corruption of data in the sent file. Lastly, for security purposes, it’s recommended to use hashing algorithms equipped with the newest technologies.
