Base64 encoding for development and testing
Base64 is commonly used to represent binary or text data in a transport-friendly format. It is useful for debugging, API tests, sample payloads, and quick conversions, but it is not encryption.
Best use cases
- Encode simple text for development and testing.
- Decode a Base64 string to inspect a non-sensitive payload.
- Check API examples, tokens, headers, or data snippets during debugging.
Common mistakes
- Treating Base64 as secure encryption. It is easy to decode.
- Pasting secrets, private keys, passwords, or customer data into browser tools.
- Forgetting character encoding differences when decoding text.
