- this page is a stub
A Hardware Security Module (HSM) is a – typically sealed – electronic circuit
with security features such as cryptographic functions (algorithms),
a cryptographic key generator, a (pseudo) random number generator and storage
facilities for cryptographic keys and passwords.
A HSM is often used to secure otherwise generic
products like computers, servers, telephones, etc.
HSMs were first used in the 1990s and are still in use today.
Some smart cards can also be used as a HSM.
