- Add more examples
- Improve coverage
- Manages & Orchestrates JWT for user login, logout & renew
- Option 1: DynamicVault (uses dynamic dispatch but requires considerable less boiler-plate code)
- Option 2: DefaultVault (uses static dispatch but requires considerable more boiler-plate code)
- Async ready
- Easy start
- No un-safe code
- Runs on stable rust
- Uses Argon (see video)
- Library approach (Requires no runtime)
- Supports plugable components
- Invalidates old refresh upon new refresh token renewal
- Invalidates old authentication upon new authentication token renewal
- Cross feeding not allowed
- Handles Thundering herd problem upon authentication token expiry
- Works with any web-server, any password hashing, and any backend (here)
- Fully functional webserver with actix and postgres

-
To begin use
login
with user and password-
Upon successful login is provides user will be provided with JWT pair (authentication/refresh)
-
Authentication token is then provided to access any resources
-
Refresh token is used to renew an authentication token upon expiry
-
-
Use
resolve_session_from_client_authentication_token
with user and authentication_token to restore user session -
Use
renew
with user and refresh_token to generate new authentication token -
Use
logout
with user and authentication_token will remove all tokens associated with the user -
Use helper
continue_generate_temporary_token
to generate temporary token for user- Temporary token creates temporary session, and does not corrupt the original session info
- Temporary token cannot be used to login/logout/renew/revoke original session
- Temporary token does not have refresh key (this is intentional), to avoid token refresh
- Note: DynamicVault users can directly use instance method
generate_temporary_token
- Typical use-case: Forgot Password
-
Use helper
resolve_temporary_session_from_client_authentication_token
to restore user temporary session- Temporary session are isolated instance, and thus has no fingerprints of the originals session
- Typical use-case: Reset Password
