useSecureStore

Encrypted key/value storage for secrets (tokens, etc.), backed by Electron safeStorage (OS keychain). Values are encrypted at rest in userData/nextop-secure-store.json; plaintext is never written.

const { isAvailable, setItem, getItem, removeItem, hasItem, clear } = useSecureStore()

Member	Type	Notes
`isAvailable`	`() => Promise<boolean>`	Whether OS encryption is available (e.g. false if a Linux keyring is missing).
`setItem`	`(key: string, value: string) => Promise<boolean>`	Rejects if encryption is unavailable (won't store plaintext).
`getItem`	`(key: string) => Promise<string \| null>`	`null` if the key is absent.
`removeItem`	`(key: string) => Promise<boolean>`
`hasItem`	`(key: string) => Promise<boolean>`
`clear`	`() => Promise<boolean>`	Wipes the whole store.

import { useSecureStore } from 'nextop-app'

const store = useSecureStore()

if (await store.isAvailable()) {
  await store.setItem('apiToken', 'secret-value')
  const token = await store.getItem('apiToken')
}

This protects per-user/local secrets at rest. It does not make it safe to embed shared/central DB master credentials in app code — see the Security Model.
