Base64algoritmilla

Base64algoritmilla, often referred to simply as Base64, is a binary-to-text encoding scheme. It is designed to represent binary data in an ASCII string format. This is useful when binary data needs to be transmitted over media that are designed to handle only text. The algorithm works by taking groups of 3 bytes (24 bits) of input data and converting them into 4 Base64 characters (each representing 6 bits).

The Base64 alphabet consists of 64 characters: the uppercase letters A-Z, the lowercase letters a-z, the digits 0-9, and two additional symbols, typically '+' and '/'. For padding, if the input data is not a multiple of 3 bytes, the '=' character is used at the end of the encoded string. One '=' indicates that the last group had 2 bytes, and two '==' indicate that the last group had 1 byte.

Base64 encoding is not a form of encryption, as it is easily reversible. It is primarily used for embedding binary data, such as images or files, within text-based formats like JSON, XML, or email. It ensures that the binary data remains intact during transmission without being corrupted by text-based protocols. Other common uses include data URLs and storing authentication credentials in HTTP headers. The standardized Base64 alphabet can vary slightly depending on the implementation.
