I need an algorithm in php that generates keys for my software and writes the key to the database as well. The key should be 'irreversible' so the inputted data should be completely hidden. Please only submit a bid if you have a working knowledge about cryptography. A simple xor, and, or and not algorithm will not be accepted. The variables you get as input are: Registers name, purchase date, reseller name and country. There is one constant value that is the companies name. Should be easy if you have a working knowledge of cryptography (2~3 hours work). The output must be in the following format: But one that will actually result in a code in the format: sDi-qXL-EJw-U47 Or in regex: (w{3}-){3}wd{2}

Hi, I need URGENT HELP in doing Assignment based on Computer Security and C++ to be completed in 2-3 days time. The main purpose of this lab is for you to gain hands-on experience with public key cryptography algorithms, in particular RSA cryptosystems. A generalization of the standard two-prime RSA is ‘multi-prime RSA’ in which modulus contains more than two primes. Encryption, decryption, signature generation and verification in multi-prime RSA are similar to that of two prime RSA; however computational costs of decryption and signature generation can be lowered if the Chinese Remainder Theorem (CRT) is used (you are not expected to implement CRT for this lab) If you are sure that you can help me in this deadline then please contact me asap and i will give ...

Hi, There is a sentence at the beginning of the document. It says "Find the solutions of following questions(or solve them, it is up to you). Then prepare a report thatcompares this solutions with the solutions of your real homework." I'll make the second part. I need your help for only the first part. So, I need the solutions of the questions. It says "Find the solutions of following questions" but I could not find them with an internet search.

I read at your resume and note that you uses Android and cryptography. I have 10 games that make it in Adobe Flash, and we want to post it over Android Store and Mac Store. At Mac Store, we are having error to upload it due to bad security signature and never they can be uploaded to the store, they run correctly over our Ipad and Ipod. The thing is just tell me whats wrong with my Mac configuration, help me to upload the games correctly and help me to post the same games at Android Store. I can pay to you 250 USD for that work. Are you interested?

Write c# code in silverlight that encrypts data and write python code that decrypts the data; use AES cryptography. If I encrypt 'Hello World', I want to get 'Hello World' when I decrypt it again. For the python code you must only use the Pycrypto library.

The task is to port the original project (developed in C++) to pure Ansi C. This will require familiarity with certain cryptography concepts, peer-to-peer programming, multi-threading, and a number of C++ libraries (e.g. Boost) as more than 50% of the code comprise of libraries. Only Ansi C compliant libraries can be used in the target project and all libraries must be open source. Required completion time is 30 days max. The project is purely for academic purposes and there are no commercial interests. Feel free to ask questions if interested.

Hi, This project would be suited for computer science students (better if existing student). I need a series in 5 parts, each part being approx 1500 words. The topic has to be a technical computer science topic, and I am open to suggestions. You can go for any algorithm (like compression, AI, cryptography etc) or networking or anything that you consider your strong point. The first part has to be basics of the topic which a bit techy person can understand. In subsequent parts, you can increase the technicalities. I would appreciate if at least one part is devoted entirely to the application and demonstration of the topic (sample devices, code etc). Please do NOT copy wikipedia or any source in the internet. If you use something as a reference, do mention it...

...nhage-Strassen algorithm ? F?rer's algorithm. The last functions are described below. ## Deliverables division:Here is an excerpt from wikipedia that I think explains things perfectly for division. "Methods designed for hardware implementation generally do not scale to integers with thousands or millions of decimal digits; these frequently occur, for example, in modular reductions in cryptography. For these large integers, more efficient division algorithms transform the problem to use a small number of multiplications, which can then be done using an asymptotically efficient multiplication algorithm such as Toom-Cook multiplication or the Sch?nhage-Strassen algorithm. Examples include reduction to multiplication by Newton's method as described above[5...

“Java Password Based Encryption(JPBE)” Password-Based Encryption (PBE) derives an encryption key from a password. In order to make the task of getting from password to key very time-consuming for an attacker. JPBE is an implementation of Password-Based-Encryption which is developed on JAVA platform Using JCA(Java Cryptography Architecture).
