Valv is an open-source Key Management System (KMS) built for modern cloud environments. It is heavily inspired by Google Cloud KMS and their internal Keystore.
⚠️ IMPORTANT: Valv is currently in technical alpha stage and does not implement all features fully. It is not suitable for production use. APIs and functionality may change at any time without notice. Use at your own risk.
Valv's Keystore is designed to encrypt millions of data-encryption-keys (DEKs) using a much smaller number of key-encryption-keys (KEKs). The KEKs are wrapped using the Root Keystore master key and stored in a highly available FoundationDB cluster.
Valv's KMS is designed to be compatible with popular cloud KMS protocols, with a focus on modern cloud environments. While the specific protocol for compatibility has not been finalized, Google Cloud KMS is a strong contender due to its alignment with the Google Cloud Envelope Encryption whitepaper, which inspired Valv's design.
A Google KMS compatibility layer can be found in the examples/google-kms directory, showcasing potential integration with Google Cloud KMS protobuf. However, please note that the final protocol choice is still under consideration.
