About this tool

When to encrypt text vs file

Use text encryption when sending a secret message over a channel that has no end-to-end encryption (SMS, email, public chat). The output is base64, so it copies and pastes cleanly. Use file encryption when the data is already a file, or when the text is too long for inline pasting.
