Creating and Managing Cryptographic Keys

What Are Cryptographic Keys?

Cryptographic keys are digital certificates used to sign your invoices with a Cryptographic Stamp Identifier (CSID). They ensure invoice authenticity and integrity.

Creating Keys

1. After enablement, navigate to the Key Management section
2. Click "Create New Key"
3. Give your key a descriptive name (e.g., "Production Key 2026")
4. Download and securely store the key files

Device Registration

Your System Integrator registers your device with NRS using your cryptographic keys. This process:

• Links your device to your NRS account
• Enables digital signing of invoices
• Creates a trust chain for invoice validation

Security Best Practices

• Never share your private keys with anyone
• Store keys in a secure, encrypted location
• Use separate keys for sandbox and production environments
• Rotate keys periodically as recommended by NRS
• Keep backup copies in a secure offline location

Key Revocation

If you suspect your keys have been compromised, immediately:

1. Contact NRS support
2. Revoke the compromised key
3. Generate new keys
4. Update your systems with the new keys
