About Base64 Encoding
Base64 is a binary-to-text encoding scheme that represents binary data in ASCII string format by translating it into a radix-64 representation.
Use cases: Email attachments, embedding images in HTML/CSS, data URLs, API authentication tokens, and transmitting binary data over text-based protocols.
Not encryption: Base64 is encoding, not encryption. The data can be easily decoded by anyone. Don't use it to hide sensitive information.
Character set: Base64 uses 64 characters: A-Z, a-z, 0-9, +, / and = for padding.
