Base64 Encoding Chart

Base64 is one of the most common encoding methods for transmitting 8-bit byte codes on the web. It's a method of representing binary data with 64 printable characters. You can refer to RFC2045-RFC2049 for detailed MIME specifications, or often use ASCII code values for keyboard keys during client development; these values usually don't need to be memorized and can be looked up in a table when needed.
