In their own words
CrystalKey 360
CrystalKey 360 is an API-based control layer for managing cryptographic policy and automating key lifecycles across hybrid environments. It supports governance of ownership, approvals, and evidence, and automates key rotation through API integrations. Native data-protection capabilities include tokenization, MACing, data masking, code signing, database encryption, encryption, and decryption. Logging across supported environments is intended to improve visibility, accountability, and evidence collection. The product is designed to work alongside existing cryptographic infrastructure, with integrations listed for HSMs from Thales, Utimaco, Entrust, and Futurex, as well as AWS, Azure, GCP, other cloud platforms, and supported key stores. Identified use cases include cryptographic estate consolidation, shared trust infrastructure, payment-key management, and preparation for algorithm transitions and key migration. It supports AES, 3DES, RSA, EC, and HMAC keys, with external key control through BYOK. Platforms include API, Linux, self-hosted, web, and Windows. Pricing is on request; prospective customers can request a demo or use-case discussion.
OpenKCM (Open Key Chain Manager)
OpenKCM (Open Key Chain Manager) is a free, open-source key management service for governing encryption keys and protecting data at rest. It supports BYOK key import and HYOK, which keeps master keys in a customer’s infrastructure. Its recursive L1–L4 hierarchy makes data keys dependent on higher-level keys. Governance and policy control are handled by CMK, while Krypton performs cryptographic execution; applications request key operations through the KMIP API.
The Gateway is designed to run near applications, such as in Kubernetes or a cloud VPC, and the same software can operate across AWS, Azure and on-premise environments. Customer root keys can remain in AWS, Azure or GCP key services, or on-premise HSMs, while OpenKCM holds a reference to the L1 key. A kill switch can halt downstream key use by removing that reference or revoking the root key. CMK connects to a corporate identity provider and sends audit logs to SIEM systems. The project’s CMK and Krypton components are actively being developed; encryption and decryption operations are in progress, while audit export, high availability and disaster recovery are planned for 2027.
