decryptConversationTitle

decryptConversationTitle(encryptedTitle: string, address: string): Promise<string>

Defined in: src/lib/db/chat/lazyDecrypt.ts:148 

Decrypt a single conversation title on demand.

Designed for the lazy display path: pair with listConversationsLazy and call this once a row is actually visible.

Behavior:

• Plaintext input (no enc: prefix) is returned unchanged. This covers conversations created before encryption was enabled and keeps the helper safe to call unconditionally from rendering code that may receive a mix of encrypted and plaintext titles.
• Encrypted input is decrypted via decryptField, which uses the same per-version cached CryptoKey as the eager path — no new key derivations are triggered.
• Concurrent calls for the same (address, encryptedTitle) share a single decrypt promise.
• The result is memoized in a 256-entry LRU.

Throws if the encryption key for address isn’t loaded. (The underlying decryptField would otherwise silently return the ciphertext, which would surface to the UI as a literal enc:v3:... title — strictly worse than a thrown error the caller can catch.)

Parameters

Returns

Promise<string>

The decrypted plaintext title.
