Kindly post a comment if you have experience with cryptography and/or blowfish encryption algorithm. Write a few lines about what you have done in the past that is relevant with the specs below and any other comments you may have. Anyone who has at least 6 past jobs *and* at least 9 i n average will receive a reply back. Loose specs (these are not final/preceise specs): Program that makes blowfish encrypted virtual drive so when the encrypted file is open then it shows up as a virtual drive on the user machine (like another/extra drive). See more complete specs as below: ## Deliverables a) program that can make an encrypter container with triple-blowfish (up to 50 GB size per container). B) Login should have 12 fields where the code can be entered (up to 60 characters per field even though only 20-25 characters are viewable) C) Characters 0-9 and a-z should also be on the login screen where they are put random for each and every login. (so, the characters will never appear int eh same order (to protect against key-loggers). D) when creating the container then the user must make random movements with the mouse and random typing keys for XX seconds (say, 60 seconds - with a count down timer) to provide random data for the encryption. e) every mis-typed login should double the amount of time before a new F) when entering the password then it must be typed 2 times G) possible to change the password by enterin the old password and then entter the new password 2 times. Question: 1) is it possible for the container to compress the data inside? 2) Is it possible to make it so it is possible to have 2 areas inside the container - one area that is "write only" (but area is *only* read while the user is logged in? Of course, somehow the container must inform how much space is available for that area (the other area is read/write only when user is logged in). 3) is it possible to make a version of the above (a to G) with boothauthorization so the entire harddisk can be encrypted with 1344 bit blowfish - and where bootup is only possible after entering the password? 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). * * *This broadcast message was sent to all bidders on Friday Aug 12, 2005 11:50:49 AM: Hi Bidders, It has come to my attention that here is an opensource encryption progra at [login to view URL] that closely suits my needs. So, kindly revise your bids so they reflect modification of the prgram from [login to view URL] accordng to the specs given.

If you wish to bid on that bid request then kindly do so. In case you have trouble finding the bid then please contact me. Kind regards, John ## Platform xp/win 2000 or linux
