The Base64 encoding algorithm receives an input stream of 8-bit bytes. It processes the input from left to right and organizes the input into 24-bit groups by concatenating three 8-bit bytes. These 24-bit groups are then treated as 4 concatenated 6-bit groups. Finally, each 6-bit group is converted to a single character in the Base64 alphabet ...

Base64. In computer programming, Base64 is a group of binary-to-text encoding schemes that transforms binary data into a sequence of printable characters, limited to a set of 64 unique characters. More specifically, the source binary data is taken 6 bits at a time, then this group of 6 bits is mapped to one of 64 unique characters.
Oct 14, 2008 · The base64 is a binary to a text encoding scheme that represents binary data in an ASCII string format. base64 is designed to carry data stored in binary format across the channels. It takes any form of data and transforms it into a long string of plain text.
Nov 28, 2023 · So you need base64 when: Incompatible data is transmitted through the network. First of all it's a problem of emails – for example, encoding is necessary when you need to attach an image to a textual message. This was the reason why base64 was first introduced. Incompatible data is stored in files or elsewhere.

The history of the Base64 started long ago, in those times when engineers argued how many bits should be in a byte. Now we use eight-bit bytes, but before that were used seven-bit, six-bit, and even three-bit bytes. By the time the eight-bit encoding was approved as a standard, many systems used old encodings and did not support the “new standard”....
Initially, the algorithm was named as “printable encoding” and only after a couple of years, in June 1992, RFC 1341 defines it as “Base64”. Since this algorithm uses 64 basic charactersit was not difficult to give it a name (especially that Base85 already existed). Therefore, I think it will not be a problem for you to guess what means the names of...
During encoding, the Base64 algorithm replaces each three bytes with four bytes and, if necessary, adds padding characters, so the result will always be a multiple of four. Simply put, the size of the result will always be 33% (more exactly, 4⁄3) larger than the original data. The formula for calculating the length of the result string without padd...
Base64 is most commonly used to encode binary data (for example, images, or sound files) for embedding into HTML, CSS, EML, and other text documents. In addition, Base64 is used to encode data that may be unsupported or damaged during transfer, storage, or output. Here are some of the applications of the algorithm: 1. Attach files when sending emai...
Base64 is not an encryption algorithm and in no case should it be used to “hash” passwords or “encrypt” sensitive data, because it is a reversible algorithm and the encoded data can be easily decoded. Base64 may only be used to encode raw result of a cryptographic function. Roughly speaking, in terms of information security, Base64 is just a foreig...

Aug 26, 2024 · Base64. Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by transforming it into a radix-64 representation. The term Base64 originates from a specific MIME content transfer encoding. When the term "Base64" is used on its own to refer to a specific algorithm, it typically refers to ...
