Abstract
Examples associated with cryptographic key security are described. One example system includes a secure storage accessible to a basic input/output system (BIOS). A BIOS security module stores an authorization value in a fixed location in the secure storage. The authorization value is stored by the BIOS during a boot of the system. A cryptographic key module reads the authorization value from the fixed location, overwrites the authorization value in the fixed location, and obtains a cryptographic key using the authorization value.
