Difference Between Encryption, Encoding, and Hashing
Encryption | Encoding | Hashing |
---|---|---|
Encryption is a type of encoding technique where the message is encoded using an encryption algorithm so that only authorized persons can access that information. | Encoding is a technique where the data is transformed from one form to another. | Hashing is a technique where the data is converted to hash using different algorithms present there. |
Encryption is a technique used for protecting the confidentiality of the data. | Encryption is used for preserving the usability of the data. | Hashing is simply used for checking the integrity of the data. |
Appropriate Keys are used in the Encryption. | No Keys are used in Encoding. | No Keys are used in Hashing. |
Encryption can be reversed back to its original form by using appropriate keys. | Encoding can be reversed back to its original form. | The hashed one cannot be reversed back to its original form. |
Example: AES Algorithm, RSA Algorithm, Diffie Hellman | Example: BASE64, UNICODE, ASCII, URL Encoding. | Example: MD5, SHA256, SHA – 3. |
Encryption vs Encoding vs Hashing
Pre-Requisite: Encryption, Encoding, Hashing.
Encryption, Encoding, and Hahsing are similar kinds of things and have little difference between them. They all are used to change the format of the data or data transformation for different purposes. We will discuss them separately. Let us first discuss the definition of all these three processes and then we will move to see how they differ.
