Encryption vs. Encoding: What's the Difference?

Edited by Harlon Moss || By Janet White || Published on December 22, 2023
Encryption is the process of converting information into a secure format, unreadable without a key. Encoding is the process of converting data into a specific format for storage, transmission, or processing.

Key Differences

Encryption is a security process where information is converted into a code to prevent unauthorized access. Encoding, however, transforms data into a different format for compatibility or efficiency in processing or storage.
Encryption is designed to protect data confidentiality, making it accessible only to authorized users. Encoding is meant for maintaining data integrity and ensuring it's correctly processed by computers.
An encryption process requires a key for both encrypting and decrypting information. Encoding follows a standardized or known algorithm that does not require a key for converting back to the original format.
Encryption is critical in data security, particularly for sensitive information like financial or personal data. Encoding, on the other hand, is used in routine data processing, like encoding videos for streaming or files for storage.

Encryption and Encoding Definitions


Protecting information confidentiality.
Encryption is vital for online transactions.


Preparing data for transmission.
The data was encoded for efficient transmission.


Preventing unauthorized access.
Encryption ensures that only authorized users can access the data.


Data format transformation.
Encoding the video made it compatible with different players.


Secure data transformation.
They used encryption to protect the emails.


Converting data for processing.
Encoding text for computer processing is essential.


Using keys for data security.
The system uses strong encryption for data protection.


Using standard formats.
The file was encoded in UTF-8 format.


Conversion into a cipher.
Encryption converted the message into an unreadable format.


Ensuring data integrity.
Encoding ensures the data remains intact during transfer.


The process or result of encrypting data.


To convert (a message or other information) into code.




To format (electronic data) according to a standard format.


(cryptography) The process of obscuring information to make it unreadable without special knowledge, key files, or passwords.


(Genetics) To specify the genetic code for (a protein, for example).


(cryptography) A ciphertext, a cryptogram, an encrypted value. Usually used with the preposition "of" followed by the value that is hidden in it.


To convert information into code.


The process of converting messages in ordinary language, or other information into a secret coded form that cannot be interpreted without knowing the secret method for interpretation, called the key.


To format electronic data according to a standard format.


The activity of converting from plain text into code


(Genetics) To specify the genetic code for a protein.


(computing) The way in which symbols are mapped onto bytes, e.g. in the rendering of a particular font, or in the mapping from keyboard input into visual text.


A conversion of plain text into a code or cypher form (for decoding by the recipient).


Present participle of encode


The activity of converting from plain text into code


Is encryption visible to users?

Often, it's transparent to end-users.

What is encryption used for?

To secure data from unauthorized access.

Is a key needed for encryption?

Yes, for encrypting and decrypting data.

Can encryption be broken?

It's challenging but possible with enough resources.

Do all systems use encryption?

It's common in systems handling sensitive data.

Do we always notice encoding?

Not always; it's often a background process.

What is the purpose of encoding?

To convert data for compatibility and processing.

Is a key needed for encoding?

No, encoding follows standard algorithms.

Is encoding necessary for all data?

It's essential for certain types of data handling.

Can encrypted data be lost?

Yes, if the key is lost or corrupted.

Can encoded data be easily read?

Yes, if the format is known.

Is encryption legally required?

In some cases, especially for sensitive data.

Is encoding relevant for all industries?

It's widely applicable in many sectors.

Does encoding change the content?

No, it changes the format, not the content.

Is encryption foolproof?

It's highly secure, but not entirely foolproof.

Can encoding be customized?

Yes, depending on the requirements.

Can encoding standards vary?

Yes, different standards exist for different needs.

Can encryption slow down systems?

It can, due to the extra processing required.

What types of data are encoded?

Various types, including text, video, and audio.

How does encryption affect data size?

It can increase the data size slightly.
