If we are building a web service that communicates using JSON format which is text based then we can attach binary data encoded in base64. We can use this trick to convert email attachments to text and send the email as if it is completely text. For example, there are some systems that only work with text data such as SMTP protocol. Note that for every 3 bytes of data there are at least 4 bytes of base64 data.Ĭonverting bytes to plain text can have many benefits. Base64 maps each 6 bits in the input stream into an ASCII character from the following set (A-Z a-z 0-9 + / =) where = is used for padding (will see what padding means later). Note that with only 6 bits we can represent a maximum of 64 characters, hence it is called base64. The goal is to convert the 8 bit stream into 6 bit characters. ASCII, UTF-8), image, email attachment, etc. The input data can be a string of characters (ex. It explains how Python handles Unicode and string data types.īase64 encoding starts with a stream of bytes that could represent any data. For beginners, I highly recommend that you check the following article. Understanding how characters are represented is very important to make sense of base64.
