What is Base64 Encoding?
Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format. It is most 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 textual data.
Common Use Cases
- Embedding small images directly into HTML or CSS (Data URIs).
- Sending binary attachments in emails via MIME.
- Passing complex data in URLs without breaking the link structure.
Is Base64 Secure?
A common mistake is thinking Base64 is a form of encryption. It is NOT. Anyone can use a Base64 Decoder to revert the string to its original form. Never use it for sensitive information like passwords.
