Encryption and hashing are very popular members of the cryptography family. Let’s figure out some major differences between encryption and hashing in this article.
What is Hashing?
Hashing is a method that can convert any form of data into a key or unique string of text with the help of a hash function. Here, it is not possible to fetch the information from the hash key.
What is Encryption?
Encryption is the process of converting the original readable data (plaintext) into alternative or non-readable data (ciphertext).
Difference between Hashing and Encryption
| S.No. | Hashing | Encryption |
|---|---|---|
| 1 | Hashing is the process of transforming the details into a key using a hash operation. | Encryption is the process of converting plaintext into ciphertext. |
| 2 | The objective of hashing is indexing and fetching entities from the database. | The objective of encryption is to convert information to keep it confidential from everyone to maintain security. |
| 3 | In hashing, we cannot fetch the original details by any means. | In encryption, we can easily retrieve the information by using the encryption key. |
| 4 | Hashing is more secure than encryption. | It is less secure as compared to hashing. |
| 5 | SHA256, MD5 are examples of hashing. | RSA, Blowfish, and AES are examples of encryption. |
| 6 | Here, the statement can be read by another person. | The encrypted statement cannot be read or modified by another person. |
