What is the difference between encoding and encryption?

Encoding is the process of converting data into a different format using a scheme that is publicly available, while encryption is the process of converting data into a format that is unreadable without a key, ensuring confidentiality.

Can you give me examples of each?

Sure! An example of encoding is Base64, which is used to encode binary data into ASCII text. An example of encryption is AES (Advanced Encryption Standard), which secures data by transforming it into a format that can only be decrypted with a specific key.

When should I use encoding instead of encryption?

You should use encoding when you need to ensure data integrity and compatibility, such as when transmitting data over media that only supports text. Use encryption when you need to protect sensitive information from unauthorized access.

Are there any security risks with encoding?

Yes, while encoding itself is not a security measure, it can expose data if not used in conjunction with encryption. Encoded data can be easily decoded, so sensitive information should always be encrypted.
