Abstract
Techniques for providing cryptographic keys for encrypted system volumes on machine instances in virtualized and/or distributed systems are described herein. At a time after detecting the requirement for a cryptographic key by a virtual machine instance, one or more computer system entities within a computer system invoke one or more computer system capabilities at least to create one or more virtual hardware devices capable of representing or providing appropriate cryptographic keys. The virtual hardware devices are connected to the machine instance under the control of the computer system so that the encrypted system volumes may be used. After the cryptographic key is no longer needed, it is detached from the machine instance.
