The Crypt library does not work for Ruby 1.9 and later. You can use this gist instead. It requires no gems: https://gist.github.com/kajic/5686064

url = 'http://localhost:3000?username=vam&paswd=1234&street=hyd&contact=999999999&company=raymarine&city=hyd&state=UP&country=ZP&zip_code=543211'
encrypted_url = Cipher.encrypt_base64('your secret key', url)

Shamelessly stolen and adapted, this appears to be what you want.

require 'rubygems'
require 'crypt/blowfish'
require 'base64'

plain = "http://localhost:3000?username=vam&paswd=1234&street=hyd&contact=999999999&company=raymarine&city=hyd&state=UP&country=ZP&zip_code=543211"
puts plain

blowfish = Crypt::Blowfish.new("A key up to 56 bytes long")
enc = blowfish.encrypt_string(plain)

mimed = Base64.encode64(enc)

puts mimed


$ ruby blowfish.rb 
http://localhost:3000?username=vam&paswd=1234&street=hyd&contact=999999999&company=raymarine&city=hyd&state=UP&country=ZP&zip_code=543211

Of course, if you need the encrypted contents to serve as an URL, then prepend http://localhost:3000/foo?q= to the encrypted contents, and provide a /foo/q GET handler that can decrypt the string and do whatever it is you need to do with it.
