Encryption työt

Your task is to design automated solvers for the shift and Vigen`ere ciphers. You must use C as the underlying programming language, in order to get prepared for the following assignments. Each solver should be completely automated, i.e., upon reading a text file containing the target ciphertext (given as command-line argument), it should print the encryption key and the decrypted plaintext without any user interaction. Test your code on the following ciphertexts, and answer these questions: (a) What is the key of the cipher? (b) What is the decrypted plaintext?

Project Description Highlights The Mission: We are building "QuantumShield," a high-performance, user-friendly desktop application that protects sensitive SMB data against "Harvest Now, Decrypt Later" threats using standardized Post-Quantum Cryptography. Key Technical Focus: This is not a standard encryption project. We require implementation of ML-KEM (Kyber) and ML-DSA (Dilithium) within a Hybrid Cryptographic Scheme (PQC + Classical AES-256). The Deliverable: A functional MVP for Windows/macOS featuring a "One-Click Shield" drag-and-drop interface and a "Quantum Health Dashboard" that monitors file vulnerability status. Required Tech Stack: High-performance systems programming (e.g., Rust, C++, or Go) with direct experie...

I need Microsoft Purview Sensitivity Labels fully design...people see the right information. Start by reviewing our existing Microsoft 365 tenant, then propose a clear label taxonomy that reflects our business needs. Once approved, configure the labels, policies, and auto-labeling rules, making sure encryption is applied and permission restrictions behave correctly across the three workloads. Finish with validation tests, a succinct admin run-book, and a short end-user guide so the team understands when and how labels apply. Acceptance criteria: • Every targeted location inherits the correct label. • Encryption activates exactly as defined. • Access restrictions match the policy settings in real-world tests. • Handover documents and quick-start gu...

...“sent” Look & feel Please mirror the current HDFC Bank mobile design as closely as possible—colours, typography, and general layout. Accuracy matters because the joke depends on immediate visual credibility. Behaviour & data Everything can run fully offline. A simple local JSON or SQLite store is fine for persisting the fake balance and transactions between sessions; no authentication, encryption, or live APIs required. I should also be able to update the balance and add or delete transaction rows myself without touching code—an in-app edit mode or an external config file would work. Platforms & deliverable Android APK is my first choice because that’s the phone I’ll use, but if you prefer Flutter or React Native, let me kn...

I’m putting together a lightweight yet secure meta-editing environment focused on code. The core need is a true code editor—nothing WYSIWYG or plain-text—able to read and write encrypted project files so that source remains protected end-to-end. Here is the essence of what I’m after: • A desktop or web-based editor purpose-built for coding tasks. • Built-in encryption/decryption of files or project folders using modern, open algorithms (AES-256 or similarly strong). • Smooth, familiar coding workflow: open an encrypted file, make edits, save, and the file is automatically re-encrypted without exposing plaintext on disk. • Clean, well-documented codebase so I can extend the tool later. Technology stack is open for discussion; fe...
