B64Base64 Encode/Decode

What is Base64 Encoding/Decoding?

Base64 is an encoding scheme that converts binary data into an ASCII string. It is widely used to safely transmit binary data in text-based systems such as email attachments, image data URIs, JWT tokens, and API authentication headers. Characters that may be corrupted in certain environments — such as non-Latin scripts or special symbols — can be safely transferred once converted to Base64.
