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.
