Enter the message or password you want to share securely. After you submitted the message by pressing the "Create secret" button, you will get a link. Send this link to your messaging partner so she can read the secret message.
Attention! The message can be read only once! After it's read, the message will be destroyed and can not be restored. Also note that if you send the link through an application which provides preview of websites, it may tries to download and create preview for this link as well by fetcing the URL. It means that this third party tool will read and destroy the secret. To pervent it, it's suggested to use the JavaScript enabled version of the application which can address this issue with add some additional mechanism.
