...files with 230 million entries. my servers are overloaded and I simply afraid to run this task right now. - Do some analysis on bitcoin address generation and write a simple php script that will take address bit & sha256 hash on input as private key and generate hash160 & pack it into "address". preferably without using openssl functions as there're no native support of ECC (Elliptic curve cryptography) under CentOS version of openssl. Please note that I'm able do it myself but just do not have time right now. So you must be confident how to do it - no time wasters here. I need this done in ONE day. Budget cap is $50. Also since I'm a freelancer myself and I know how hard it was to get first projects - I'll consider only newbies fo...

...limited knowledge of this area. Each article is to be fairly short (something like 500 to 1500 words) and are intended to act as introductions or overviews to a category in which more detailed, more technical articles will be written by other members of my team. All articles will be in the fields of Information, Network and Cyber Security. They will cover topics such as Application Security, Cryptography, Forensics, Malicious Software, Network Security and Physical Security. Many of the articles will be more like extended definitions and it is intended that all articles feature as little technical terminology as possible. More like a lay-man's guide to a topic. They will be similar to Wikipedia articles, in their purpose and scope although often much shorter, much more...

I'm looking initially for 10 images to be created, as banners to go on top of a web site. The banners must be 650px by 150px and must be able to be cut down to 300px by 150px for "thumbnails". All images should be in the same style and there should be one image per category. The categories are all Computer Security related and are things like: Cryptography, Forensics, Network Security and Malicious Software. The artist is given freedom to create any image within the category theme for each category although if more specific information for each one is need that can be supplied too.

I am proposing an encryption system which has the potential to make things a little faster and could possible stir cryptography to claim openness as well. I call it eXCIPHER: It is described by way of mathematical elements of the GF. This is necessary for grasping the specifics. This is followed by the Knight's tour analogy: The key rationale (external context), embedded in the design proposed. The description of the cryptographic system will be clearly shown to volunteers or prospects. Other interested people (students) are welcomed to it. The implementation and practicality of the cipher (eXCIPHER) is been patterned as a prototype in java at the time of writing. My goal will be to make this cryptographic system available for collective development. The promise of nu...

...apparent, but with a human touch. Some visual styles to draw from would be Bladerunner, Ghost in the Shell, Tron-Legacy, and the 2012-13 Star Trek movies. Basically, NSA meets Bladerunner. Some background information on what we would like to showcase would be something along the lines of technologies that we make use of, such as machine learning, GPU processing, massively parallel programming, and cryptography. A lot of the work we do is funded by the Department of Defense so keep that in mind. I should add data science research, data visualization, historical and graphical information, computational biology, and complexity sciences to that list as well. What we have in mind is something that is competent and has the coolness to bleed through but with a subtle sense of human touc...

...we will not assist them further than our legal obligations and therefore protecting user data from any party is the only way to achieve total privacy. No data will be stored on any individual except the e-mail addresses on the server of course and the password in an encrypted form of some type so we will not know what it is the user chooses. I believe a way of doing this is called public-key cryptography. 2. The service should only be accessible as a Tor hidden service. I understand this is not difficult to set up so if you do not know what this is, it is not a problem as it is just a way for users to access their e-mail anonymously. 3. The service must offer 3 plans. A free plan, and two paid plans, the only difference is the additional mailbox size and also personal stora...

We have a partially completed Delphi project that requires one last step to finish it off. The project is for decrypting sectors from a TrueCrypt volume. This is NOT a password cracking a program. The password is known to the user at the time of running the program. We only require a routine to decrypt any sec...skills. TrueCrypt is open source and written in C/C++. Therefore knowledge of C/C++ is required in order to understand how to perform the sector decryption. You will be supplied with the full test application written in Delphi that requires completion. No GUI skills are required, as you will only be completing the test application. Please no time wasters. If you do not know anything about Cryptography - DO NOT BID. If you do not know how to program in Delphi - D...

We are looking for a developer with experience in cryptography and "byte-level" java development with a focus on performance. The project is to develop a library that can encrypt and decrypt byte arrays using a supplied standard called CCM*. This is a variation on AES-CCM block cipher mode. The CCM* mode coincides with the original CCM mode specification for messages that require authentication and, possibly, encryption, but does also offer support for messages that require only encryption. As with the CCM mode, the CCM* mode requires only one key. There is an extensive specification which also includes test vectors that should serve as input for unit tests. Writing the unit tests to validate that it works is also part of the project. Also, there is a C implementat...

...using multiple simultaneous connections to the same game server in order to increase their odds to win. We will have to add userIDs, email address, IP addresses to a black list, and code the web site to block them from connecting to the server for a period of time. You'd have to be willing to become somewhat knowledgeable about how Bitcoins and cryptography work to do this project... but you will not need to be an expert on BitCoins or cryptography by any stretch of the imagination. You must speaks excellent English and you should be a citizen of the USA, or live in a country where you could be extradited if I catch you putting backdoors in this system... or if the Feds or my book keepers come knocking on my door, asking about shady transfers, embezzlement, etc. ...

for my MS thesis i have to simulate des, aes and aes+ecc(hybrid) encryption algorithms on wireless sensor networks using ns2, ns3, matlab or some other simulator like them and compare their results in graph. i have a due date of this project next week if you could in any way create a simulation nearly matching this or compare encryption algorithms seprately and provide their values in wsn and just make a graph it will be enough

Need to simulate multiple cryptographic algorithms (DES, AES) in WSN using NS2 comparative analysis of DES and AES can be done in any other simulator but their result values must be used to simulate a wireless sensor network to show graphs of both algorithms.
