About HID Crescendo® SDK

HID Crescendo® SDK provides integrators with API and a Command Line Interface (CLI) Tool to manage and use HID Crescendo® devices, including the Crescendo hybrid smart cards and the USB- and NFC-enabled HID Crescendo Key Series.

Either with API-level integration, or with the CLI Tool, integrators can:

Identify an inserted device by product name and device serial number
Configure PKI keys and certificates, and use them for authentication, digital signature and encryption services
Configure a device with One-Time Password options, and generate HOTP, TOTP and OCRA-compliant passwords for highly secure transactions
Configure and access PIV data objects
Configure PIN policies and PIN itself
Configure PUK, unblock PIN using PUK
Configure Management Keys
When using the FIPS-certified version of Crescendo devices, use Secure Key Injection to securely transfer OTP, PIV or Management keys to the token.
