This is obviously an url-encoded string. So, the CGI-Library is you  
saviour:

==== code ====

require 'cgi'
CGI.unescape('https%3A%2F%2Fwww.example.com%2Flogic%3Fss 
%3D1%26companyname%3DShhhhhhh%26userlogin%3Dshhhhh%40')
# => "https://www.example.com/logic?ss=1&companyname=Shhhhhhh&userlogin=shhhhh@ 
\n"

==== code ====
