Convert B64 to BIN

QUICK ANSWER
Is it possible to convert B64 to BIN?
Yes - B64 converts to BIN.

'Converting' a .b64 to .bin means decoding the Base64 back to the original binary. Windows: 'certutil -decode input.b64 output.bin'. Linux/macOS: 'base64 -d input.b64 > output.bin'. After decoding, identify the actual file type (use the 'file' command on Linux, or inspect magic bytes) and rename with the correct extension.
