Other Base64 variations share the same property but they use different symbols in the last two values. The Base64 implementation in MIME uses a-z, A-Z and 0-9 for the first 62 values. The base64 base encoding specified by RFC 4648 section 4, Base 64 Encoding. This mixture leaves the data impossible to be altered in transportation thru information systems, such as electronic mail, that were typically not 8-bit clean. Decode the Base64-encoded data in input and return the data in a new byte array. returns the ASCII bytes of the string foo. The common concept is to select a set of 64 characters that is both part of a subset typical to most encodings. Google uses cookies to deliver its services, to personalize ads, and to. The specific set of characters chosen for the 64 characters needed for the base can vary among implementations. Decode the Base64-encoded data in input and return the data in a new byte array. Base64 is generally used in a number of applications including electronic mail via MIME, and keeping complex information in XML. This guarantees that the data stays unchanged without modification during transfer. Types of URI charactersīase64 encoding schemes are generally used when there is a need to encode binary information that needs to be stored and transferred over media that are developed to deal with textual information. Basically, Base64 is a collection of related encoding designs which represent the binary information in ASCII format by converting it into a base64 representation. The term Base64 is coming from a certain MIME content transfer encoding.
