Base64 is encoding, not encryption

Base64 represents bytes with text-safe characters and is often used in data URLs, email attachments and API payloads. Anyone can decode it, so it must never be used to protect passwords, tokens or confidential information.

For structured API data, use the JSON Formatter or our Python JSON guide.
