Most file sharing services offer the ability to encrypt your data as you upload it to the server, using a technology known as SSL. This is the same technology that banks use to make sure your browser connection is secure, and you’ll often see a padlock in the address bar of your web browser. Like those sites, we use SSL to secure your browser connection too. What you may not realize, is that once the data gets to their server, it gets decrypted...and what happens from there can be a crap shoot. Many service providers will also tell you they can also store your data encrypted, but the problem is that since they are the ones encrypting it, they also hold the key. Why is that a problem? Because if someone on their end wants to read your files (or even worse, someone hacks into their system) they have the means to do so since they have access to the encryption key.
SendSafely works in an entirely different way. Rather than have us encrypt the data for you, we let your browser encrypt it before we ever see it. And even better, we don’t ever get access to the key. The key is derived from the link that only you and the people you share it with have access to. What that means is that even if we wanted to read your files, we can’t because we don’t have the key. And if someone gains access to our system they won’t be able to decrypt them either.
