They work with a 65-character subset of US-ASCII where each of the first 64 characters maps to an equivalent 6-bit binary sequence. Base64 encoding and decodingД«ase64 relies on simple encoding and decoding algorithms. For this example, the image would be shown inline with the rest of the message.

The recipient's email software will Base64-decode the encoded textual image to restore the original binary image. Note that the entire encoding for this or any other example is about 33 percent larger than the original binary data. indicates text that I haven't shown for brevity. The illustration shows that this encoded image starts with / and ends with =.

Later, it was officially presented as Base64 in RFC 2045: Multipurpose Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies, and subsequently revisited in RFC 4648: The Base16, Base32, and Base64 Data Encodings.Д«ase64 is used to prevent data from being modified while in transit through information systems, such as email, that might not be 8-bit clean (they might garble 8-bit values). Base64 request for comment documentsД«ase64 was first described (but not named) in RFC 1421: Privacy Enhancement for Internet Electronic Mail: Part I: Message Encryption and Authentication Procedures. Each Base64 digit represents exactly 6 bits of binary data. What is Base64?Д«ase64 is a binary-to-text encoding scheme that represents binary data in a printable ASCII string format by translating it into a radix-64 representation. What is Base64 and how do I use this API? This post answers these questions. Some will also remember Java 8 for introducing various small but useful features such as the Base64 API. Requires import .binary.Java 8 will be remembered mainly for introducing lambdas, streams, a new date/time model, and the Nashorn JavaScript engine to Java. 8.GetString(64String(base64EncodedData)) You should use Base64 whenever you intend to transmit binary data in a textual format. When and why would you use Base64 encoding? It also uses a = character at the end of a string to signify whether the last character is a single or double byte. MIME Base64 encoding is the most common, and is based on the RFC 1420 specification. Encoding data in Base64 results in it taking up roughly 33% more space than the original data. Other examples of Base64 encoding are Radix-64 and YUI's Y64. It is used to transmit attachments via email over the Simple Mail Transfer Protocol (SMTP). MIME, which stands for Multi-Purpose Internet Mail Extensions, is the most common that is seen today. The term Base 64 is generic, and there are many implementations. RGFuJ3MgVG9vbHMgYXJlIGNvb2wh What is Base64 encoding?

The MIME implementation uses the characters A-Z, a-z, and 0-9 for the initial 62 values that it can use to encode data. This is done via the MIME implementation of Base64. An example of this is an attachment in an email. To allow binary data to be transmitted with textual data it must be encoded.
