Class SHA224

ReadonlyblockSize

clean

• clean(): void

• Cleans internal buffers and resets hash state.

  Returns void

cleanSavedState

• cleanSavedState(savedState): void

• Cleans state returned by saveState().

  Parameters

  • savedState: SavedState

  Returns void

digest

• digest(): Uint8Array

• Returns the final hash digest.

  Returns Uint8Array

finish

• finish(out): this

• Finalizes hash state and puts hash into out. If hash was already finalized, puts the same value.

  Parameters

  • out: Uint8Array

  Returns this

reset

• reset(): this

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

  Returns this

restoreState

• restoreState(savedState): this

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

  Parameters

  • savedState: SavedState

  Returns this

saveState

• saveState(): SavedState

• 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

• update(data, dataLength?): this

• 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
  • OptionaldataLength: number

  Returns this
