Introduction To Signature Commands
The commands are operations that enable you to generate digital signatures using the private keys stored securely on your Cryptnox hardware devices. These commands are essential for:
- Authenticating transactions, messages, and documents.
- Ensuring their integrity and origin.
Core Signature Commands Explained
One primary signature command is the EC Signature. This command allows the card applet to sign any 256-bit hash provided by the you, utilizing Elliptic Curve Digital Signature Algorithm (ECDSA) with NIST P-256 (secp256r1) parameters. This functionality is crucial for various cryptographic operations, including blockchain transactions and secure communications.
