What is Base64?
Base64 represents binary data using a set of 64 printable characters. It is commonly used in APIs, data URLs, and email attachments.
Is Base64 secure?
No. Base64 is an encoding format, not encryption. Anyone can decode it, so do not use it to protect passwords, tokens, or other sensitive information.
