Quick answers

Frequently asked questions

Does Base64 encoding make text confidential?

No. Base64 is a reversible representation of bytes, not encryption. Do not use it to protect passwords, tokens, or private documents.

Which text encoding is used before Base64?

Matrix encodes the input as UTF-8 bytes, then converts those bytes to Base64. That preserves ordinary multilingual text for compatible decoders.
