blowfish encrypted url in ruby

How to encrypt and decrypt the url using blowfish in ruby?

ex: url= http://localhost:3000?username=vam&paswd=1234&street=hyd&contact=999999999&company=开发者_StackOverflow中文版raymarine&city=hyd&state=UP&country=ZP&zip_code=543211

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.

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)
