Base64 is a binary-to-text encoding scheme that represents binary data using 64 characters (A-Z, a-z, 0-9, + and /). It's commonly used to transmit binary data through systems that only support text content.
URL-safe Base64 replaces characters that have special meaning in URLs (+ and /) with URL-safe alternatives (- and _). This makes the encoded string safe to use in URLs without additional encoding.
Base64 is an encoding method, not an encryption method. It doesn't provide security or privacy - anyone can decode Base64 data. Use proper encryption if you need to secure your data.
