Base64 decoding reverses the Base64 encoding process, converting encoded ASCII characters back into the original binary or text data.
Base64 encoding represents each 3 binary bytes as 4 ASCII characters using the characters A-Z, a-z, 0-9, plus (+) and slash (/). An equal sign is used at the end as padding for missing bytes. Decoding reverses this process to recover the original data.
Base64 encoded data is commonly found in HTTP headers, email attachments, data URLs in HTML, and encryption keys.
Base64 IS NOT an encryption algorithm, it is merely a data encoding algorithm providing absolutely no protection!
