How to use the Base64 Encoder and Decoder.
Base64 is an encoding, not encryption. Use the correct byte encoding and validate the input rather than treating unreadable output as secure storage.
Make the workflow fit your task.
Choose standard or URL-safe Base64 and define how text becomes bytes, normally UTF-8. Validate alphabet and padding according to the destination before decoding. For binary content, report bytes or an appropriate file format rather than assuming readable text.
- What you provide
- Text or Base64 string.
- What you get
- Deterministic encoding or decoding with validation.

Decisions and troubleshooting.
Can Base64 protect a password or other secret?
No. Anyone who has the encoded value can decode it. Use it only as a representation format.
Why does a decoded string contain replacement characters?
The bytes may be binary or use a different text encoding. Confirm the original encoding before interpreting them as text.
Try it with your own source.
Replace the example with your material in the task prompt. Keep the requirements you need, then copy the task into WebAct.
