Encryption

Seald allows you to secure any document (Office, PDFs, videos...) with a simple drag and drop in the application. Once secured, the document can be sent safely through any communication channel chosen by the user (email, Internet, USB key,...).

Via the desktop application

1. In the application, drag and drop one or more documents or click on the encryption zone.	2. Select the contacts for whom you want to secure the document, or search for new contacts with their email address.
3. You also have the possibility to choose the storage mode for the encrypted documents (mandatory on the first use).	4. Wait until encryption is completed.
5. In case the "generate link" option has been chosen, a link is created for each document. Copy the link and send it through the channel you want.

WARNING

The document is always encrypted for you as well. You will be able to open it.

TIP

On the first use, you must choose the storage mode for the encrypted documents:

• saving the encrypted file next to the clear file;
• replacing the clear file with the encrypted version;
• creating a download link for the encrypted file.

On subsequent uses, the last storage mode used will be selected by default.

You can now send your encrypted document in the .seald format, or the newly created download link, without risk through the communication channel you want: email, Internet, USB key, ... If your recipient does not have Seald, they can open it using the Seald file format.

Via the right click (on Windows only)

On Windows, you can right-click on a file and use Seald to encrypt it. You can also right-click on a Seald file (.seald) to access the revocation and tracking functions.

Allow downloading at encryption

At encryption, you will find the option "Allow download" which allows your recipients who do not have Seald to download a clear version of your files when opening them on your browser. If this option is disabled and:

• either the format of one of your files to be encrypted is not previewable;
• or that its size exceeds 50 MB;

you should allow the download so that your recipients can access it through the download.
