Base64 Encoder / Decoder Online
Brief description of Base64
Base64 encoding is used to represent any binary information, whether image or * exe-file, in the form of text, more precisely, the sequence of a specific set of characters. number 64 indicates the number of characters used to encode the data (see their set. below). Due to its versatility is widely used in data transmission, wherein other variants representation other than text, unacceptable. Base64 is also used as the easiest and most affordable way to "surrogate" encrypt text information from a direct reading: The information takes the form of chaotic character set decoding of base64 return it to its original view.
Base64 is used to:
- encode any non-text information to the text
- simple encryption (hiding) the text without cryptographic protection
The character set for encoding in base64: ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/
The basic principle of operation.
The basic principle of Regardless of their origin, all data is stored as binary data: sets of zeros and ones, so having an equal representation in the PC memory. Base64 encoding in essence is quite simple: the original binary content is taken and split into groups of 3 bytes (24 bits), and then each group is further divided into 4: 6 bits each. Last (probably) is not a multiple of six group is padded with zeros. These groups of six bits are then mapped to one of the character set that supports the format base64.
