vti-common

Shared server-side infrastructure for VTA and VTC services in the Verifiable Trust Infrastructure workspace.

Overview

vti-common provides the foundational types and implementations shared across the VTA and VTC service crates:

  • Store abstraction -- Store and KeyspaceHandle enum dispatch to either a local fjall embedded database or a vsock-proxied backend (for TEE enclaves). Both variants support transparent AES-256-GCM encryption via .with_encryption().
  • Auth infrastructure -- JWT encoding/decoding (EdDSA / Ed25519), session management, and axum FromRequestParts extractors (AuthClaims, ManageAuth, AdminAuth, SuperAdminAuth).
  • ACL -- AclEntry, Role, CRUD operations, and validation.
  • Error types -- AppError enum with IntoResponse for consistent HTTP error handling.
  • Config types -- AuthConfig, LogConfig, StoreConfig, MessagingConfig, AuditConfig shared across services.

Feature Flags

Feature Default Description
encryption No AES-256-GCM encryption for KeyspaceHandle.with_encryption()
vsock-store No VsockStore + VsockKeyspaceHandle (Linux only -- requires tokio-vsock)

Usage

Add to your Cargo.toml:

[dependencies]
vti-common = "0.5"
