Fail closed instead of storing a cleartext password when no OS keystore is available - #522
ravjotbrar wants to merge 4 commits into
Conversation
When the OS has no secure store (e.g. headless/minimal Linux without
gnome-keyring or KWallet), safeStorage.isEncryptionAvailable() is false
and the encrypt IPC previously returned the plaintext password, which the
renderer then persisted to localStorage while the UI implied it was
protected.
Fail closed:
- The encrypt handler now returns { ok, value } and never returns
plaintext; adds a secure-storage:is-encryption-available IPC.
- The connect/save paths keep the entered plaintext in memory so the
current session still connects, mark the connection isPasswordEncrypted
= false, and warn the user (with an actionable keyring hint).
- persistConnections is the single localStorage write path: a connection
whose password could not be encrypted is written with password
undefined (and the transient flag dropped), so no cleartext reaches
disk. On next use the connection re-prompts for the password.
Passwordless connections are unaffected (encryption is never invoked).
Adds wrapper tests for the new structured contract and persistConnections
strip tests.

Self-review of the fail-closed change found three paths where the isPasswordEncrypted marking was lost while the plaintext password remained, so persistConnections would not strip it: - The connect-success epic rebuilt the saved entry without the flag, so the primary path (connect then persist) still wrote plaintext. - updateConnectionDetailsEpic copied connectionDetails onto the stored entry without the flag. - The connectPending reducer took the flag only from the payload, so retry/resume/auto-reconnect re-dispatches (which omit it) wiped the marking in Redux. Carry the flag through all three, preserving an existing marking when a re-dispatch omits it while still letting an explicit value override it. Adds reducer regression tests for the preserve/override behavior. Signed-off-by: ravjotb <ravjot.brar@improving.com>

The cluster node connect flow reuses a sibling connection's stored password via selectEncryptedPassword, which returned only the password string. With the fail-closed change that value can now be plaintext (marked isPasswordEncrypted=false on its source connection), and the reuse dispatch targeted a new connectionId with no marking — so the persistence strip was bypassed and the plaintext could be written to disk as if encrypted. Rename the selector to selectClusterPassword and return the password together with its source connection's isPasswordEncrypted marking, and include that marking in the connectPending dispatch.

Two more paths could persist a plaintext password because an absent isPasswordEncrypted marker is treated as safe: - A core-field edit with an unchanged password deletes the old connection and reconnects under a new connectionId with no marker, so the reducer has nothing to inherit from. Initialize the marker from the source connection when the password is unchanged. - selectClusterPassword could return a password whose source marker was absent (e.g. a connection restored from localStorage, including legacy plaintext persisted before this fix). Default the marker to false so reuse can never persist plaintext; a restored ciphertext reused this way just re-prompts on the next session instead of being saved.
