I need a production-ready AES implementation that I can drop into our stack to protect data at rest. The focus is on clean, well-documented source code that supports 128, 192, and 256-bit keys, CBC and GCM modes, plus straightforward hooks for key rotation. My environment is a mix of Python micro-services and a Java back-end, so a portable C/C++ core wrapped for those languages—or native, equally secure versions—would work. What matters most is that the code passes standard NIST test vectors, includes unit tests, and ships with a concise integration guide. Deliverables: • Fully commented AES library (source + build instructions) • Test suite confirming compliance with FIPS/NIST vectors • Short README covering integration and key management reco...

...execute it. The objective is crystal clear: show me, with evidence, how an attacker could breach the site, especially around two vital areas—authentication/authorization flows and data security. Scope • Black-box or gray-box methodology is acceptable so long as you respect live-traffic limits I will provide. • Focus your effort on login, role-based access controls, session management, encryption practices, and any data at rest or in transit. • Social-engineering and network layers are outside this engagement; please stay strictly within the web application boundary. What I expect as deliverables 1. A brief kickoff plan outlining test phases, tools (Burp Suite, OWASP ZAP, Kali, custom scripts, etc.) and timelines. 2. Daily status notes during a...

...proof-of-concept that lets ordinary smartphones keep talking when every tower is down. The app must run on iOS, remain fully functional in Airplane Mode, and rely only on radios already inside the phone. Core requirements • Device-to-device discovery and auto-forming mesh that supports 2–3 hops. • Short text messages and current GPS coordinates relayed across the mesh. • Basic AES-128/256 encryption so content and location data stay tamper-free. • A simple text-based interface—no maps, no shiny graphics—just a clear log of peers, coordinates, and messages. GUI is preferred but not mandatory for this proof of concept. Technical direction On iOS you can use Multipeer Connectivity plus BLE. Feel free to suggest alternative...

My home network needs a thorough security overhaul focused on cybersecurity and data protection. I’m looking to tighten every layer—router configuration, firewall rules, Wi-Fi encryption, secure remote access, and reliable backup strategies—so that every device in the house stays protected without slowing anything down.

Their alignment with Jamaican and international regulations covering Data Protection & Privacy, Anti-Money Laundering (AML), and Electronic Payments & Transactions. You will receive architecture diagrams, user flows, API documentation and direct access to a staging environment for both apps. I am specifically interested in whether my encryption strategy, authentication logic and general vulnerability surface meet current industry best practices (OWASP Top 10, ISO 27001, PCI DSS, etc.). On the compliance side, I want a clear gap analysis that maps each requirement in the above-mentioned regulations to the way the apps currently operate. Please be prepared to reference the Bank of Jamaica sandbox guidelines as you ...

I’m ready to connect my Lovable account with GoHighLevel but need an expert to handle the technical details from end to end. The main outcome I’m after is a secure, fully-functioning integration that issues Encryption keys for public use so outside services or landing pages can tap into GHL without exposing any sensitive data. Here’s the flow I have in mind. Once the two platforms talk to each other, the system should automatically generate and surface a public-facing key pair while keeping the private component locked away. Although my immediate priority is getting those Encryption keys live, I’m open to expanding the build later to include contact management, automated email sequences, or sales-funnel tracking once the core connection is stable. Yo...

...a School Management System delivered as a dedicated mobile app for both iOS and Android. The solution must include a solid back-end, restful APIs, and a well-structured database so that the Admin, Teacher, and Student roles each see only what they should. A classic username-and-password flow is enough for the first release, but it must be implemented securely with proper session handling and encryption in place. Core modules I expect from day one are fee tracking, attendance, timetable, examination results, push notifications, and printable reports. Everything should be responsive to different screen sizes, optimised for low-bandwidth scenarios, and ready for future additions such as two-factor login or parent access without major refactoring. Deliverables • Universal iO...

I need a straightforward Android application that lets users access the app through a secure username-and-password login screen. At this stage I am focusing only on Android, so you can use Android Studio with Java or Kotlin—whichever you are most comfortable with. Core scope • Clean, intuitive login interface • Secure credential handling (local encryption or a backend such as Firebase/Auth0—open to your best-practice suggestion) • Well-structured project files and clear comments so I can maintain the code later Optional next steps (not in this job but good to keep in mind) could include subscription flows or cloud integration, so please architect the code with scalability in mind. When you hand over the APK and full source code, I will test the...

I need a complete payment gateway that can process Credit/Debit cards, Cryptocurrency, and Bank transfers seamlessly across Web, Mobile, and in-store POS environments. Robust security is non-negotiable, so the build must include Two-factor authentication, end-to-end Encryption, and smart Fraud detection baked into every transaction flow. To keep the scope crystal-clear, here’s what I must walk away with: • A scalable back-end capable of handling the three payment methods above • Front-end or SDK components that drop into web apps, native mobile apps, and common POS terminals • Security layer implementing the three features named earlier, with compliance reporting enabled • Clean API documentation and a minimal admin dashboard so I can track transacti...

We already have a large audience and intend to aggressively promote the platform through so...

I’m putting together a “flash-style” application that lets adult learners explore core cryptocurrency concepts in a classroom setting. The aim is to keep everything simple enough for first-time students yet authentic enough that they see real-world mechanics in action. Here’s what I need the build to cover: • Data encryption built in from the ground up so students can encrypt and decrypt sample strings and immediately view the results. • Basic blockchain integration that spins up a local test chain, writes a few dummy transactions, and then visualises block creation. • A small, self-contained wallet module that can generate keys, sign test transactions, and show balances—all within the local sandbox, no live coins involved.
