The to-base64 operation encodes the input value into Base64. Base64 is a binary-to-text encoding scheme commonly used for transmitting binary data over text-based protocols such as HTTP.
How it works
- Input – a string or binary value.
- Output – the Base64-encoded representation of the input.
- If the input is empty or cannot be processed, the result is an empty string.
Examples
| Input | Output |
|---|---|
| hello | aGVsbG8= |
| 12345 | MTIzNDU= |
| {“id”:1} | eyJpZCI6MX0= |
| (empty) | “ (empty string) |
Usage in PalDock
Use to-base64 when you need to:
- Encode credentials, tokens, or payloads for APIs that require Base64 (e.g. HTTP Basic Auth, JWT header encoding).
- Safely transmit binary content (images, files) in text-only fields.
- Normalize data into a consistent, ASCII-safe representation.
Best Practices
- Combine to-base64 with prefix to build Authorization headers, e.g. Bearer {token}.
- Ensure that the receiving API expects Base64 — do not use this operation unless the integration specifically requires it.
- Be aware that Base64 increases data size by ~33%, so avoid using it for very large payloads unless necessary.
