Abstract
Methods, systems, and devices for cryptographic key management are described. A memory device can issue, by a firmware component, a command to generate a first cryptographic key for encrypting or decrypting user data stored on a memory device. The memory device can generate, by a hardware component, the first cryptographic key based on the command. The memory device can encrypt, by the hardware component, the first cryptographic key using a second cryptographic key and an initialization vector. The memory device can store the encrypted first cryptographic key in a nonvolatile memory device separate from the hardware component.
