what is base64?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It’s commonly used to encode binary data, such as images, audio files, and other non-text data, so that it can be transmitted over text-based protocols like HTTP or embedded into text-based documents like XML or JSON.
Base64 encoding works by taking 3 bytes of binary data and converting them into 4 ASCII characters. Each ASCII character represents 6 bits of the original binary data. If the length of the input binary data is not a multiple of 3, padding characters (‘=’) are added at the end to ensure that the length of the encoded string is a multiple of 4.
Base64 encoding is not encryption; it’s simply a way to represent binary data using printable ASCII characters, making it suitable for transmission via text-based channels that may not support raw binary data. However, it’s worth noting that Base64 encoding does not provide any form of data compression or security.
