Encoding & Decoding
Base64, Base32, Hex and other encoding algorithms (Not for security purposes)
What is Encoding & Decoding?
Encoding is the process of converting data into a different format, but unlike encryption, it does not serve a security purpose. Encoding is used to transfer or store data between different systems. For example, Base64 encoding converts binary data into text format, making it usable in email attachments or web pages. The encoding process is reversible (decoding) - meaning you can return to the original data.
Use Cases
- Email attachments (MIME)
- Embedding binary data in web pages
- API data transfer
- Database storage
- URL encoding
- Data visualization
Key Features
- Reversible
- No security purpose
- Optimized for data transfer
- ASCII compatible
- Fast processing
