Staticcreate

• create<C extends Ciphersuite>(
      ciphersuite: C,
      vk: VerifyingKey<C>,
      sig: Signature<C>,
      msg: Uint8Array,
  ): Item<C>

  Create a new batch Item from a VerifyingKey, Signature and a message to be verified.

  Type Parameters

  • C extends Ciphersuite

  Parameters

  • ciphersuite: C

    The ciphersuite to use

  • vk: VerifyingKey<C>

    The verifying key

  • sig: Signature<C>

    The signature

  • msg: Uint8Array

    The message to be verified

  Returns Item<C>

  A new batch Item

  Throws

  FrostError if pre-verification or challenge computation fails

verifySingle

• verifySingle(): void

  Perform non-batched verification of this Item.

  This is useful (in combination with cloning) for implementing fallback logic when batch verification fails. In contrast to VerifyingKey.verify(), which requires the message data, the Item type is unlinked from the message.

  Returns void

  Throws

  FrostError if verification fails

clone

• clone(): Item<C>

  Clone this item.

  Returns Item<C>
