What is Base64 encoding used for?

Base64 encoding is commonly used to encode binary data such as images, audio files, and other media for transmission over text-based protocols. It's essential for email attachments, embedding images in HTML/CSS, and storing complex data in JSON or XML formats.

Is Base64 encoding secure for sensitive data?

Base64 is not an encryption method but rather an encoding scheme. It doesn't provide any security or confidentiality. For sensitive data, you should use proper encryption methods before Base64 encoding for transmission.

How does Base64 encoding work?

Base64 encoding works by converting every 3 bytes of binary data into 4 ASCII characters. It uses a set of 64 characters (A-Z, a-z, 0-9, + and /) to represent different binary values, hence the name 'Base64'.

Why does Base64 encoded text end with = signs sometimes?

The equals sign (=) is used as padding at the end of Base64 encoded text when the input length is not divisible by 3. This ensures the output length is always a multiple of 4 characters.
