Base64 is encoding, not encryption
Base64 changes binary or text data into characters that are easier to move through systems that expect text.
It does not hide data securely. Anyone can decode Base64 if they have the encoded string.
Decode before debugging
Base64 often appears in API responses, tokens, data URLs, configuration values, and copied snippets. Decoding it can reveal whether the value is text, JSON, or something else.
If the decoded text is JSON, formatting it after decoding can make the structure much easier to inspect.
- Check for private data
- Do not paste secrets into public examples
- Format decoded JSON before editing it
Encode when a text-safe value is needed
Encoding is useful when a value must travel through a text-only field, but it should not be used as a security layer.
If you need real secrecy, use proper encryption or secure storage instead.
