Alternative to if-then-else or case statements

I am parsing keywords from a string and wondering if there is an alternative method other than massive if-then-else statements or using a switch statement. Any direction would be helpful

application = application.downcase
if(application.include?("ssl"))
     return "SSL"
elsif(application.include?("ssh"))
     return "SSH"
elsif(application.include?("dce"))
     return "DCE"
elsif(application.include?("https"))
     return "HTTPS"
elsif(application.include?("https"))
     return "http"
else
     return "nil"
