If the number of bytes are not in numbers of three, then padding is used = for 1 byte and = for 2 bytes.Ĭonsult wikipedia for more information. Those 6 bits form a number corresponding to the index in the character set supported by Base64 (A-Z, a-z, 0-9, + and /). The resulting buffer of 3 bytes is then broken in 4 packs of 6 bits each. How does Base64 encoding work?īytes forming the data are broken into buffers of 24 bits (3 bytes at a time). Concrete examples would be sending images in an XML file or in an email attachment. This is useful when binary data needs to be sent over media that are usually designed to handle textual data. Message Digester (MD5, SHA-256, SHA-512)īase64 is an encoding scheme used to represent binary data in an ASCII format.
