But if the operating system itself gets compromised or if some other mechanism might allow for the reading of all memory then secrets in one program’s part of memory may still be readable by outsiders. They do a good job of making sure that only the authorized process can read and manipulate certain things in memory. Modern operating systems are much better about this.
Programs could easily cause other programs or the whole system to crash, and malware was very easy to create. Back in the old days (when I had to walk two miles through the snow to school, up hill, both ways) some operating systems did not do a good job of enforcing memory protection. It is the operating system’s (OS’s) job to make sure that one process can’t access the memory of another. We don’t want some other program running on your computer to peer what is in 1Password’s memory when 1Password is unlocked. And it is a security problem if one program can read the memory of another program. It is a Bad Thing™ if one program can mess with another program’s memory. It needs this both for the actual program and for the data that the program is working on. Ordinary memory protectionĪ program running on a computer needs to use the system’s memory. SGX does a lot of other things, too but the feature I’m focusing on now is the privacy it offers for regions of system memory and computation. It is a security layer in the chip that cryptographically protects regions of operating system memory.

Their most recent CPUs include the ability for software running on Windows and Linux to create and use secure enclaves that are safe from attacks coming from the operating system itself. Intel, as most of you know, make the chips that power most of the desktop and laptop computers we all use. It has been great working with them, and I very much look forward to continuing this collaboration.
I would also like to say that we would not be where we are today without the support of many people at Intel. SGX support in 1Password isn’t ready for everybody just yet as there are a number of system requirements, but we are very happy to talk about what we have done so far and where we are headed. Soon (some time this month) 1Password for Windows customers running on systems that support Intel’s SGX will have another layer of protection around some of their secrets. We have been working with Intel over the past few months to bring the protection of Intel’s Software Guard Extensions (SGX) to 1Password. 🎶 Them keys, them keys, them random keys (3x)Īnd that is a simplification! But it is the appropriate simplification for what I want to talk about today: Some of our intrepid 1Password for Windows beta testers can start using a version of 1Password 6 for Windows that will have an extra protection on that “master key” described in that song.🎶 And the derived key comes from the MP.🎶 And the master key’s encrypted with the derived key.🎶 Each item key’s encrypted with the master key.The details differ for our different data formats, but here is a little ditty from our description of the OPVault data format to be sung to the tune of Dry Bones.

Instead, your Master Password is used to derive a key encryption key which is used to encrypt a master key. You might reasonably think that your data is encrypted directly by your Master Password (and your secret Account Key), but there are a number of technical reasons why that wouldn’t be a good idea. These are 77-digit (256-bit) completely random numbers. These include the various encryption keys that 1Password uses to encrypt your data. But there are lots of secrets that 1Password has to juggle that you never see. There are the secrets that you see and manage such as your passwords and secure notes and all of the other things you trust to 1Password. When you unlock 1Password there are lots of secrets it needs to manage.
