You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: fingerprinter.rb
    path of file: ./repos/identity-idp/app/services/pii
    
    the code of the file until where you have to start completion: module Pii
  class Fingerprinter
    def self.current_key
      IdentityConfig.store.hmac_fingerprinter_key
    end

    def self.fingerprint(text, key = current_key)
      digest = OpenSSL::Digest.new('SHA256')
      OpenSSL::HM
    
    def self.verify_queue(text, fingerprint)
      IdentityConfig.store.hmac_fingerprinter_key_queue.each do |key|
        return true if ActiveSupport::SecurityUtils.secure_compare(
          fingerprint, fingerprint(text, key)
        )
      end
      false
    end
