Katta bring zero-config storage management and zero-knowledge key management for teams and organizations.

This library implements the Katta Server API as Cyberduck protocol features for the Katta Client.

Features:

• Client code is generated for Katta Backend API through openapi.json
• Katta Server interaction (workflows like first login, vault creation, (automatic) access grant and sync of storage profiles and vaults): implementation and integration/regression tests.
• S3 and S3STS Cyberduck protocols for Katta (see Katta S3 Modes) incl. token exchange and AWS role chaining. Cyberduck handles OAuth 2.0 token management (authorization code grant and token refresh).
