Auric manages their own PCI and HIPAA compliant cryptographic key management service called the n-key™ service.
The n-key™ service securely generates cryptographic data encryption keys that are themselves encrypted using the public/private key OpenPGP technology.
Key rotation is automatic.
The service has been in use since 2011 and used by hundreds of payment application deployments. Auric uses the n-key™ service for both their own in-house AuricVault® data encryption and custom service deployments.
