_stateHi: Int32Array = ...

blockSize: number = BLOCK_SIZE

Block size

digestLength: number = DIGEST_LENGTH

Length of hash output

Methods

  • _initState(): void
  • clean(): void
  • Cleans internal buffers and resets hash state.

    Returns void

  • Cleans state returned by saveState().

    Parameters

    Returns void

  • digest(): Uint8Array
  • Returns the final hash digest.

    Returns Uint8Array

  • finish(out: Uint8Array): SHA512
  • Finalizes hash state and puts hash into out. If hash was already finalized, puts the same value.

    Parameters

    • out: Uint8Array

    Returns SHA512

  • Resets hash state making it possible to re-use this instance to hash other data.

    Returns SHA512

  • Function useful for HMAC/PBKDF2 optimization. Restores state saved by saveState() and sets bytesHashed to the given value.

    Parameters

    Returns SHA512

  • Function useful for HMAC/PBKDF2 optimization. Returns hash state to be used with restoreState(). Only chain value is saved, not buffers or other state variables.

    Returns SavedState

  • update(data: Uint8Array, dataLength?: number): SHA512
  • Updates hash state with the given data.

    Throws error when trying to update already finalized hash: instance must be reset to update it again.

    Parameters

    • data: Uint8Array
    • dataLength: number = data.length

    Returns SHA512
