Hashing in cryptography is an IT security technique that offers businesses the chance to maintain data integrity and authenticity. Generally, we mix up hashing with encryption by considering them similar to each other but the reality is different. In this blog, we'll look into hashing and learn more about it. 

What is Cryptography? 

Cryptography is a methodology for protecting data and communications by using encryption so that only authorized individuals can decrypt and process when needed. As a result, unwanted exposure to data is restricted. The word "crypt" refers to "hidden," while the suffix "graphy" refers to "writing." 

Cryptography technologies are based on mathematical principles and rule-based calculations which are commonly known as algorithms to transform communications that end up making them difficult to decrypt. These algorithms are used for cryptographic key generation, cryptographic certificates, and authentication to secure data privacy, web surfing, and private transactions including credit or debit card transactions. 

Types of Cryptography 

There are mainly three types of cryptography: 

•    Symmetric Key Cryptography 
•    Asymmetric Key Cryptography 
•    Hash Functions 

What are the features of Cryptography? 

Cryptography is the means through which we can build highly robust and reliable interconnections to protect our confidentiality. Cryptographic technologies make it more difficult to breach encryption technology, enabling encrypted data, files, or network services to be accessed only by authorized users. 

The following are some features of cryptography: 

•    Confidentiality - It offers data encryption and its accessibility only to the specific individual for whom it is designed. This eliminates the risk of data loss and security breaches. 
•    Non-repudiation - The creator/sender of information cannot deny his or her intention to send information at a later stage. 
•    Integrity - Data cannot be modified in storage or during the transfer between the sender and the authorized receiver again with no modification to the data. 
•    Authentication - It authenticates the identities of both sender and the receiver. Furthermore, it also verifies the destination and the origin of data before transferring. 

What is Hashing?

Hashing is a cryptographic technique for validating the originality and integrity of different input types and patterns. It is primarily used in cryptographic techniques to protect plaintext passwords from being stored in databases. Furthermore, it is additionally used to authenticate business documents, communications, and different data types. A poor hashing technique can cause serious security breaches, but neglecting to employ hashing to encrypt confidential business data in the first place is even worse. 
How does cryptographic hashing work?

Hashing is a process of converting readable text into unreadable highly secure text. It is a one-way cryptographic process that offers irreversible and secure hashes. A hashing output doesn’t allow anyone to reproduce the content of a file. However, it helps in determining whether two files are identical by comparing them without knowing their data. 

Types of Hashing Algorithms

There are in general three types of Hashing Algorithms:

•    Secure hashing algorithm 256 (SHA256) 
•    Secure hashing algorithm 1 (SHA1) 
•    Message digest 5 (MD5) 

What makes Hashing important for businesses?

Hashing, when compared to other IT security database systems, provides a more secure and customizable technique for obtaining data. It is faster than scanning lists and arrays. In extreme cases, hashing can recover data from anything saved in a tree. Unlike other data structures, hashing does not specify the speed. However, it is very important to maintain a balance between time and space while performing hashing. To achieve stable data security always go for a reputed IT security solution provider in India. 

There are two methods to achieve this balance. 

•    Controlling speed by deciding how much space to allow for the hash table. 
•    Controlling space by selecting a recovery speed. 

Passwords that have been hashed can’t be changed, stolen, or hacked. The technique offers robust encryption with zero breach possibility. Furthermore, there is no reason to be worried if a hash code is hacked as it can't be used anywhere. 

Hashing allows two files to be quickly compared for equality. It is not necessary to open the two documents separately. Hashing evaluates them word by word, and the resultant hash value shows you right away if they are different. 

Final Words 

Ultimately, hashing and hashing algorithms are important mechanisms in IT security. We've learned about hashing's objectives, which include data integrity and authentication. We've covered what hashing is, how it works, and how hashing is used in cryptography.
