YubiKey 5 Cryptographic Module
Yubico, Inc. - FIPS 140 #5291
The YubiKey 5 Cryptographic Module (the module) is a single-chip module validated at FIPS 140-3 Security Level 2. The module is a secure element that supports multiple protocols designed to be embedded in USB and/or NFC security tokens. The module can generate, store, and perform cryptographic operations for sensitive data and can be utilized via an external touch-button for Test of User Presence in addition to PIN for smart card authentication. The module implements several major functions - FIDO, PIV-compatible smart card, OpenPGP smart card, OATH authentication, Security Domain, and YubiHSM Auth.
