Encode / Decode:

Base64 encoding is a way of representing binary data, such as images or files, as text. It works by dividing the binary data into blocks of 6 bits, and then representing each block as a unique combination of 64 characters from the Base64 character set. This allows the binary data to be represented as text, which can be easily transmitted and stored.

Base64 decoding is the opposite process, where Base64-encoded text is converted back into the original binary data. This is necessary when receiving Base64-encoded data, in order to be able to interpret and use the data as intended.

Overall, Base64 encoding and decoding is a useful way of representing binary data as text, and is often used in applications such as email and web development, where transmitting binary data can be challenging. It allows binary data to be easily transmitted and stored as text, and can then be decoded back into its original form when needed.
