What are the differences between hashing vs encryption? Hashing and encryption are the two most fundamental functions of a computer design. But there are differences between these both.
Differences Between Hashing vs Encryption
Hashing and encryption both depend on digital security for their function, but they are different because hashing is a one-way function, whereas encryption is a two-way function. Also, hashing is a process that converts data in an input string of secure data into a secure hash.
Encryption on the other hand uses two sets of keys, one public and the other private. The public key is while the private key decrypts. So, the main purpose of encryption is to provide security for data and communication.
Because of their different characteristics, hashing and encryption are for different purposes. Also, hashing is mostly used to verify the authenticity of data, whereas encryption is to secure data from unauthorized access.
Objectives
The main objective of hashing is to verify the authenticity of data. So, the main objective of encryption is to secure data from unauthorized access.
Usage
Hashing has gained popularity as it is in many applications including computer security and cryptography. Also, it is in digital signatures and digital fingerprints to protect information from unauthorized access.
Encryption takes place when plain text is into encrypted text using encryption algorithms. This encrypted text may be decrypted using a special key that enables one to convert the encrypted text into the original plain text.
Comparison Chart
Hashing is a one-way function. Encryption is a two-way function. In hashing, the data is not modified. In encryption, the data is in its encrypted form.
Hashing makes use of several algorithms for encryption. Encryption makes use of only one algorithm for encryption.
In hashing, the original data can be following certain mathematical operations. Also, in encryption, the original data cannot be without using its relevant key.
The main purpose of hashing is to verify the authenticity of data. Also, the main purpose of encryption is to secure data from unauthorized access.
Hashing is mostly used to store passwords and other sensitive data. Encryption is mostly used to secure information that is over the internet.
