Analysis of Security Algorithm Named RSA

From this value to the private key we deduce how strong the private key which composed of 904 bytes 2048 bits as shown. The algorithm will encrypt the user's passwords by the public key while the private key will be used for decryption purposes using the following code for encryption public function RSA_encrypt data if openssl_public_encrypt data, encrypted this pubkey data base64_encode encrypted else throw new Exception Unable to encrypt data. Perhaps it is bigger than the key size return data In other hand the following codes used for decryption public function RSA_decrypt data if openssl_private_decrypt base64_decode data decrypted this privkey data decrypted else data return data Where openssl_public_encrypt function is used inside RSA_encrypt data function to encrypt data with public key and stores the result into encrypted variable. As well as openssl_private_decrypt function used inside RSA_decrypt data function to decrypt data with private key and stores the result into the decrypted variable. First after the creation of both public and private keys and prepare them using setkey val function. This is followed by compression of the data to be sent in encrypted form which in our case are the passwords for users using the following piece of codes, plaintext, gzcompress plaintext. Then a created system gets the public key of the recipient using a command publicKey, openssl_pkey_get_public public key. Generate the public key for the private key using a command a_key openssl_pkey_get_details publicKey.

Types and performance analyses of the RESTful APIs

REST APIs, as well as their deficits with respect to compliance with the REST architectural style Knowing and analyzing this data in detail, may help to improve the state of the art with purposeful solutions. Software systems may face recurring design problems good solutions to which are known as design patterns that improve the design quality and facilitate maintenance and evolution of software systems. Anti-patterns are the attempted RESTful HTTP usage that creates issues showing the failed adoption of REST ideas. Sometimes it is a poor and counterproductive solution to the design issues. Therefore it is necessary to detect REST anti-patterns for improved maintenance and evolution of RESTful systems. RESTful services are gaining increasing popularity day by day Twitter, Google, Facebook, YouTube, and many more companies leverage REST. However, the usage of REST for designing and developing Web-based applications has increased which has raised the threats to common software engineering challenges. In fact like any other software system, RESTful systems also must evolve to handle new resources i.e meet new business requirements and become scalable. Even the changes in underlying technologies or protocols may force the REST APIs to change.

Highlighting the positive impacts the Smart City idea is having on the People and the Environment

For about 20 years development of smart cities has experienced technological, economic and social evolution such as the development of the tele cities, informational cities and virtual cities, inventions and innovations, privacy concerns and security concerns. The study of smart cities has therefore attracted the attention of scholars from across disciplines, like Urban planning. Architecture Environmental Science, Computer Science, Economics, Geography as well as other social science disciplines. The development of smart cities has therefore brought about both positive and negative impacts on society and the environment. This paper, therefore, aims at highlighting the positive impacts the smart city idea is having on the people and the environment, the challenges in implementing the idea and finally a suggestion of possible actions that ought to be put in place to solve the identified challenges. Positive Impacts of The Smart Cities Development Development of ICTs, Internet and Technological Innovations. The vast amount of information in the city can now be easily acquired, organized, processed and analyzed due to the advancement of information and communication technologies.

All that You Need To Know about Pointless Websites.

All that You Need To Know about Pointless Websites and how they Work Well we bring you Pointless websites that are certain to put a smile on your pretty face and they will definitely cheer you up. It is the weekend and you’re tired. You want to relax and do something fun. Have you thought of something that will ensure a good mood? Then continue reading. What are pointless websites? Neither is it innovative nor is it ingenious but it is an excessive way to waste your time. The pointless websites are nothing but an assortment of some of the world's worst useless and pointless websites. It's fundamentally a massive button that one can click to take one to those useless websites several of which you’ll know and love and others that may be completely innovative and extremely creative to you. But all of those sites share one collective peculiarity they’re useless AF. What is the purpose of pointless websites? Now the question is why would someone create a website as useless as making a worm dance with your mouse on screen ducks, are the best with flashing ducks moving images, weird and confusing facts and images on the website just to create attraction or what. No idea at all. The useless web is for those who are looking for a time pass because there are websites that are useless in a way but if you are a pointless useless person yourself you might find something catchy about them.

Study description documents of REST APIs and perform structural analysis.

Abstract. A REST API is an application program interface that uses HTTP protocol for making requests to a web server using GET, PUT,  POST and DELETE methods on the data. A RESTful API also referred to as a RESTful web service is based on representational state transfer. REST technology an architectural style and approach to communications often used in web services development. REST is a very popular architectural choice for building Web-based applications due to its resources. Many worldwide used APIs are analyzed not to be fully compliant to the principles of HTTP. In this work I intend to study description documents of REST APIs and perform structural analysis. I will base my findings on manually examining a body of publicly available API descriptions and provide conclusions about common description forms output types usage of API parameters authentication details and level of reusability. This analysis can be used as a basis for devising common standards and guidelines for API development. This project aims to classify the patterns and anti-patterns as well as mark their presence in a few real-world APIs if found. Keywords REST design patterns anti-patterns REST API structural analysis.
