Hi, I am graduated in Computer Science with 92% and I have 3 and a half years of industry work experience. I love to work with cryptographic projects. I also have A in Cryptography and Data Information Security and I completely understand working of certificates authorities, RSA(Public Key Algorithm), AES, DES, 3DES, IDEA and TwoFish. I also have research paper in this Cryptography field. I understand your requirements. I have already implemented RSA in C#, Java and between php server and mobile phone apps(iPhone and Android). I can provide your sample work of RSA in C#, JAVA, PHP, iPhone and Android. I can negotiate regarding price and time after detail requirements. Waiting for your response for further discussion. Regards, Rainbow

I have MS in Information Security with research interest of Cryptography. I have implemented Cryptography algorithms in Java and C, written security solutions in J2EE and Java, have implemented datastructures in Java, and built two websites for research / proof-of-concept purposes. Additionally, ~2 years of IT experience. I have taken Graduate level courses in Cryptography and Security that dealt with analysis of Cryptographic protocols, my Masters level project involved design of a Cryptographic protocol for a specific authentication problem in three-party settings. I have executed a number of projects that focussed almost entirely / heavily on Cryptography. I have also written Cryptographically signed Java applet for a J2EE application. Details about projects executed available on request. You might want to go through reviews project creators left for me on freelancer.com, see https://www.freelancer.com/u/ciphe.html.

Hello, I'm Mathieu, senior developer with something like 10 years of experience in Microsoft technologies such as C# .net. I'm also skilled in Asp.Net/C#, MVC, WPF, WCF. I have a good knowledge of MSSQL server and internet technologies (JavaScript, JQuery, knockout.js, HTML5, CSS3, bootstrapper etc.) as well. We could use the Cryptography namespace's implementation of the algorithm to generate a class that performs the verification.. I'm very serious and competent and my highest concern is to always get my clients 100% satisfied. So please concider my bid. Regards, Mathieu
