HSM
Hardware Security Module
A tamper-resistant device that generates, stores, and manages cryptographic keys.
An HSM is a hardened, tamper resistant device that generates, stores, and uses cryptographic keys so private keys never leave the protected boundary in plaintext. It accelerates cryptographic operations and is central to PKI, certificate authorities, and high assurance signing. Tamper detection can zeroize keys if physical attack is attempted, supporting compliance requirements. Compared with a TPM, which is a per device chip for platform integrity, an HSM is a dedicated, often higher capacity appliance for enterprise key management.
Hardware Security Module: a separate, scalable box that generates and manages keys for many systems.
Looking HSM up is step one. Getting tested on it is step two.
