<b>Base64</b><br /><br />
|
|
The term Base64 is coming from a certain MIME content transfer encoding.
|
|
Basically, Base64 is a collection of related encoding designs which
|
|
represent the binary information in ASCII format by converting it
|
|
into a base64 representation.<br /><br />
|
|
Base64 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. This guarantees that the data
|
|
stays unchanged without modification during transfer.
|
|
Base64 is generally used in a number of applications including electronic mail
|
|
via MIME, and keeping complex information in XML.<br /><br />
|
|
The specific set of characters chosen for the 64
|
|
characters needed for the base can vary among implementations.
|
|
The common concept is to select a set of 64 characters that is both
|
|
part of a subset typical to most encodings. 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.
|
|
The Base64 implementation in MIME uses a-z, A-Z and 0-9 for the first 62 values.
|
|
Other Base64 variations share the same property but they use different symbols
|
|
in the last two values.<br /><br />
