YUBICO YubiHSM v2.0

The YubiHSM 2 is a Hardware Security Module that is within reach of all organizations. It provides advanced cryptography, including hashing, asymmetric and symmetric key cryptography, to protect the cryptographic keys that secure critical applications, identities, and sensitive data in an enterprise for certificate authorities, databases, code signing and more.
Its ultra-slim "nano" form factor fits completely inside a server's USB port and also makes it highly transportable for off-line key transport or backup.

• Enhance protection for cryptographic keys
  YubiHSM 2 offers a compelling option for secure generation, storage and management of keys. Key protection is done in the secure on-chip hardware isolated from operations on the server. Most common use cases involve protecting of the certificate authorities (CAs) root key. YubiHSM 2 capabilities include: generate, write, sign, decrypt, hash and wrapping keys.
• Enable hardware based cryptographic operations
  YubiHSM 2 can be used as a comprehensive cryptographic toolbox for low-volume operations in conjunction with a huge set of open source and commercial applications spanning many different products and services. Most common use case involve on-chip hardware based processing for signature generation and verification.
