[Closed] What's the difference between encoding, encryption, and hashing?

All these techniques are used for converting the format of data. Encoding transforms data into another format using a scheme that is publicly available so that it can easily be reversed. It does not require a key. Encryption transforms data into another format and it is used for keeping the data secret. In Hashing technique, data is converted to a message digest or hash, which is usually a number generated from a string of text. Hashing is not reversible.

Encryption trades with keys which are using encrypt and decrypt the data. These keys are used to change a simple text into a cypher text and the vice versa.

Encryption is used to Security of data

Encoding:

The message is encoded by using an algorithm in encoding. However, one cipher text is produced for each plain text. The strategy used for change is not kept secret like in the case of encryption.

Encoding is used to Protection of integrity of data

Hashing:
Data is converted to a message digest or hash, which is a number generated from a string of text. These digests are important as one can effortless match the hash of sent and received messages to ensure that both are the same and no tempering is done with the data.

Hashing is used to Verification of data

The Difference between hashing and encryption is that encrypted strings can be turned back into their original decrypted form if you have the right key.

What is hashing in network security:

Hashing means safe and secure data, such as passwords or importance files. It's is the transformation of a string characters into a normally shorter fixed-length value or key that represents the original string. Hashing is used to index and recover items in a database because it is faster to find original value.

John, Your answer is good and perfectly understandable about encoding, encryption, and hashing.

• Encoding transforms data into other formatting using a scheme that is publicly available so that it can easily be reversed.
• Hashing is meant to protect or keep data such as strings (passwords usually) or file secure.
• Encryption is the process of transforming information using an algorithm.

Encryption, encoding and hashing are techniques used for converting the format of data. These methods offer various levels of security to data that has been transformed.

Encryption - is used for changing plain text into cipher text so that only authorized entities can understand it.

Encoding - is used for changing the data into a special format which makes it usable by external processes.

In hashing - the data is converted to a message digest or hash, which is usually a number generated from a string of text. Hashing is not reversible as encryption and encoding.

Usually, in data is represented in some alternate form but with different intentions.

Encoding is done to convert data to represent it in a more convenient form or say for compression.

Encryption is done to hide data and make it difficult to understand by unauthorised person. Hashing technique, data is converted to a message digest or hash, which is usually a number generated from a string of text. Hashing is not reversible.

Hope this will help you !

• Encoding is for maintaining data usability and can be reversed by employing the same algorithm that encoded the content, i.e. no key is used.
• Encryption is for maintaining data confidentiality and requires the use of a key (kept secret) in order to return to plaintext.
• Hashing is for validating the integrity of content by detecting all modification thereof via obvious changes to the hash output.

Encryption, Encoding and Hashing are kind of similar terms and are often confused with each other. So let’s discuss each term and how they are different from each other. here its is  http://www.differencebetween.info/difference-between-encryption-encoding-and-hashing
