# How MockFlow encrypts your data

> MockFlow encrypts every transfer with HTTPS, encrypts sensitive data such as passwords with a 256-bit key, and lets you password protect board and .wire files.

Encryption keeps your boards and account details unreadable to anyone who should not see them. MockFlow encrypts data while it travels between your device and MockFlow, protects sensitive data on its servers, and lets you encrypt the board and wireframe files you keep yourself.

## Encryption in transit

All data moves between your browser or the desktop app and MockFlow over SSL/HTTPS with AES 256-bit encryption. This covers everything: opening a board, editing it live with your team, uploading files and signing in. Qualys, a leader in security auditing, rates MockFlow's HTTPS setup A+.

## Encryption of sensitive data

On MockFlow's servers, sensitive information such as passwords is encrypted with a 256-bit key, so it is never stored as readable text. Backups are encrypted too. See [Where your data is stored and how it is backed up](/docs/where-your-data-is-stored).

## Password protected board and .wire files

In the MockFlow desktop app, boards and Classic WireframePro projects can be saved as files on your computer. You can protect a .board or .wire file with a password, which encrypts it with AES 256-bit encryption. Anyone who opens the file needs the password, even if the file is sent by email or copied to a USB drive. See [Password protect a board file](/docs/password-protect-a-board-file).

## Protect public links with a key

When you share a board with a public link, you can turn on **Protect with key** so viewers must enter a key before the board opens. See [Share a board with a public link](/docs/share-a-board-with-a-public-link).
