Base64 Encoder / Decoder
Convert UTF-8 text to Base64 and decode it again, without sending it anywhere.
Unicode in. Base64 out.
Encode UTF-8 text into standard Base64, or decode padded and unpadded Base64 back into readable UTF-8 text.
Base64 is encoding, not encryption. Do not treat it as protection for secrets.
