What is Base64 Encoding?
Base64 is an encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation. It is widely used to ensure that data remains intact without modification during transport through information systems that might not be 8-bit clean.
Common Use Cases
- Data URIs: Embedding small images directly in HTML or CSS.
- Basic Auth: Transmitting credentials in HTTP headers.
- JSON Payloads: Sending binary metadata through purely textual JSON APIs.
