Private generateCredential

• generateCredential(req): Promise<SerializedPCD<PCD<unknown, unknown>>>

• Generates the requested credential, if possible. Takes a CredentialRequest and produces a serialized PCD which consists of a signature PCD (e.g. a semaphore signature PCD) which wraps a FeedCredentialPayload. This payload contains a timestamp, and may contain a PCD if a) the feed requests one and b) CredentialManager can find a matching PCD.

  Parameters

  • req: CredentialRequest

  Returns Promise<SerializedPCD<PCD<unknown, unknown>>>

Private getCachedCredentials

• getCachedCredentials(type, cacheId): undefined | SerializedPCD<PCD<unknown, unknown>>

• Parameters

  • type: undefined | string
  • cacheId: string

  Returns undefined | SerializedPCD<PCD<unknown, unknown>>

Private getCurrentCacheId

• getCurrentCacheId(): string

• Returns string

Private purgeExpiredCredentials

• purgeExpiredCredentials(): Promise<void>

• Returns Promise<void>

Private semaphoreSignPayload

• semaphoreSignPayload(payload): Promise<Credential>

• Parameters

  • payload: CredentialPayload

  Returns Promise<Credential>

Private setCachedCredentials

• setCachedCredentials(request, value): void

• Parameters

  • request: CredentialRequest
  • value: SerializedPCD<PCD<unknown, unknown>>

  Returns void
