Hardware Security Modules (HSM)

Cloud HSMs provide FIPS 140-2 Level 3 hardware key protection without managing physical devices. Here's how AWS CloudHSM, Azure Managed HSM, and Google Cloud HSM compare, and where cloud HSM creates operational dependencies.

A key ceremony is the formal, witnessed process of generating cryptographic keys inside an HSM. Here's what happens during a ceremony, why it's required for CA keys, and where ceremonies go wrong.
