Is Base64 encryption?
No. Base64 is a reversible text encoding and provides no confidentiality, authenticity, or password protection.
Does this tool handle Unicode text?
Yes. It converts strings through UTF-8 so characters outside basic ASCII can be encoded and decoded correctly.
Can I process arbitrary binary files?
No. This interface is designed for text input and output, not direct file or binary-stream conversion.
