TODO

• Pure cli version of LiMe Server to enable deployment on linux headless server.
• Adapt Travis CI ATS
• Rebuild The Protocol with Restful API (json)
• Gradle the project
• Use HTML to render the email content
• Use Hibernate or Mybatis as a persistence framework
• The process bar for the file transmission
• A fancy website for LiMe
• Merge all the services out of P.R.China to provide a global-based service.
• Store the password on the server with MD5
• Local password storage encrypted with AES using a random key, the random key stored with AES digested with MD5
• Transport the message with AES and keys digested with MD5
• Open group chat for all users
• Enable user to reset the password via a server-sent Email
• Redirect LiMe to the new domain name
• Email should be a unique key (LiMeSeedRecoverPassword)
• The file transmission function
• Use the database to validate and manage the user
