What is Base64?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with text.
This ensures that the data remains intact without modification during transport. It is widely used in email (MIME), data URLs, and basic authentication.
Common Use Cases
- •Data URLs: Embedding small images or other files directly in HTML or CSS.
- •Basic Auth: Encoding credentials for simple HTTP authentication.
- •Data Storage: Storing binary data in text-based formats like JSON or XML.
Developer Tips
Not Encryption
Remember that Base64 is an encoding, not encryption. It can be easily decoded by anyone and should not be used for sensitive secrets without actual encryption.
Padding Characters
Base64 strings often end with one or two "=" characters. These are padding characters used to ensure the encoded string is the correct length.
