Difference Between Hashing And Encryption. In this article, you will come up with information about what is hashing, what is encryption, what is the main difference between hashing and encryption, and a comparison between hashing and encryption. There are various methods to make the data secure and two of them are hashing and encryption. Have a look at the differences between these two methods.

What Is The Main Difference Between Hashing And Encryption?

The main difference between hashing and encryption is that the:

-Hashing is a process in which data is converted into a unique number that is generated from a string of text. It is a mathematical operation. The hashing output cannot be converted into its original form.

-Encryption is the conversion of readable data into unreadable data to avoid and prevent any unauthorized access. The encrypted data can be decrypted into its original form.

Hashing is a process in which data is converted into a unique number that is generated from a string of text. It is a mathematical operation. The hashing output cannot be converted into its original form. Hashing is used to verify the data.

The output in hashing is known as hash or message digest. The input in hashing has an arbitrary length, but the output is always fixed in it. In hashing, the hashing algorithm is used to convert the data. But the data cannot be converted back into its original form. A unique data will produce the same hash. The process of hashing is easy to perform, but very difficult to reverse. Some various hashing functions are MD5, SHA1, and SHA-256.

What Is Encryption?

Encryption is the process in which we convert readable data or information into unreadable characters. This is done to prevent any unauthorized access to the data. The encrypted data is treated just like any other data. You can store it or send it in an e-mail message. If you want to access or read the data, it should be decrypted or decipher first to make it into readable form.

The original message is converted to an unrecognizable message in order to send it through the network. It cannot be identified, thus the hacker cannot steal it. A special type of encryption algorithm and a key is used to convert the original data into encrypted data. This converted data is known as Ciphertext. And encryption is also known as enciphering.

Comparison Between Hashing Vs Encryption:

-Hashing output cannot be reversed.
-Encrypted data can be reversed.

-Hashing does not use keys.
-Encryption uses keys.

-In hashing, data is converted into numbers generated from a string of text.
-In encryption, algorithm and key transmit the data into an unrecognizable form.

-Hashing is used to verify the data.
-Encryption is used to secure the data.

-Hashing is used for sending files, searching or passwords.
-Encryption is used to transfer high security and sensitive business information.
