Para esta implementação deverá ser usada uma máquina virtual com sistema operacional Linux (FEDORA), em sua última versão, que seja capaz de instalar pacotes de aplicativos atualizados. Será necessária para esta implementação a instalação dos serviços do DNS, HTTP e OpenSSL. Para que esta configuração funcione, o servidor implementado na máquina virtual deverá possuir IP fixo, pois, constitui pré-requisito para o serviço de DNS. É necessário gravar um vídeo demonstrando a implementação do serviço DNS e HTTPS conforme detalhamento a seguir: 1. Deverá ser configurado um servidor de DNS com 2...

Hi, We operate a META search project connected with BING. We are looking to hire a backend developer to join our team to integrate Bing places results into our search results similar to how Google places rank in their search results. We need to understand similar projects you have worked on. Our platform is built using: Apache 2+ (mod_rewrite) PHP 7+ (MySQLnd, OpenSSL, cURL, mbstring) MySQL 5+ We have updated our design using html / css and are in the process of building our own text ads platform similar to Google Ads to show on search results. But it is priority that we integrate the Bing places information into our search results as often people just search for a local business / café / and need the address or phone number.

You've to build a websocket client using Emscripten and also incorporate OpenSSL as a dependency for SSL support. You have provided with the code for the websocket client, which you will use to build the Emscripten version of the client. You have provide instructions on how to build the Emscripten version and an example HTML page that demonstrates the functionality of the client. Regarding the SQL project, I understand that the code for the project has been provided and will not change the outcome of the Emscripten jobs. However, it seems like you are concerned about the quality of the documentation and want me to focus on it and make it clearer for someone with no programming experience to understand.

I need someone very skilled in C language that understand very good how TLS/SSL works and able to understand OpenSSL source code. I am interesting to modify the library for sending custom client hellos (for avoid JA3 fingerprint). For spoof JA3 fingerprint, you need to have access to send custom client hellos (SSL Extensions, Ciphers, etc...) You can search on Google how JA3 fingerprint works and what they capture, problem is that OpenSSL can't send the client hellos you can, in the order that you want. If you know how to do that, let me know.

... namely because of speed I chose stream algorithm instead of block algorithm. I work with transmitting important files over unsecured channels on a regular basis, at the moment I used and use the usual openssl aes-128-cbc, but the encryption speed leaves much to be desired...

Hi. I need a cryptography programmer who can code for me a highly sophisticated elliptic curve cryptography key generator (preferably using OpenSSL) which I can hash with SHA-256. If ECC is too complex, RSA may also be substituted as a replacement as I believe both of these methods use a public and private key. I already have the working SHA-256 hash code but I need someone to help me with the ECC or RSA code. The idea would be that we would hash the data and then sign the hash. This will prove that whoever generated this hash has the private key. Then you get the data that you want to verify, calculate the hash on it and then check that. If the calculated hash matches the one in the signature then the signature is valid. At this point we will have have high confidence that the da...
