The YubiHSM 2 is a USB-based, multi-purpose cryptographic device for servers. Its diminutive physical size is ideal for installation directly into internal or external server ports.
PKCS#11 API version 2.40
Yubico Key Storage Provider (KSP) to access Microsoft CNG. The KSP is provided as 64-bit and 32-bit DLLs
Full access to device capabilities through Yubico’s YubiHSM Core Libraries (C, Python)
2048, 3072, and 4096 bit keys (with e=65537)
Signing using PKCS#1v1.5 and PSS
Decryption using PKCS#1v1.5 and OAEP
Curves: secp224r1, secp256r1, secp256k1, secp384r1, secp521r, bp256r1, bp384r1, bp512r1, Ed25519
Signing: ECDSA (all except Ed25519), EdDSA (Ed25519 only)
Derivation: ECDH (all except Ed25519)
SHA-1, SHA-256, SHA-384, SHA-512
Import and export using NIST-approved AES-CCM Wrap with 128, 196, and 256 bit keys
On-chip True Random Number Generator (TRNG) used to seed NIST SP 800-90A Rev.1 AES-256 CTR_DRBG
Asymmetric key pairs generated on-device may be attested using a device-specific Yubico attestation key and certificate, or using your own keys and certificates imported into the HSM.
