暗号化について

Cryptography is the science of protecting sensitive information by transforming it into a code that is illegible to unauthorized users. Cryptographers use mathematics and computer algorithms to create cryptographic protocols and encryption techniques that allow data to be kept secure, in the same way a safe can be used to protect valuables from theft or destruction. Cryptographers are technology professionals specifically trained in the art and science of encrypting digital information, making them extremely valuable assets for businesses, governments, researchers and individuals looking to protect their sensitive data.

The demand for expert Cryptographers has grown significantly in recent years, as new laws have been introduced regulating data security and protection, forcing businesses of all types to recognize the importance of safeguarding sensitive information. As such, Cryptography has become an essential tool in a variety of industries, from healthcare to finance, marketing, law and many others.

Here’s some projects that our expert Cryptographers have made real:

  • Creating presentations around cryptography
  • Translating coding languages relevant to cryptography
  • Constructing comparison studies between different cryptographic algorithms
  • Developing secure network communication protocols through Diffie-Hellman key exchange and AES encryption
  • Enveloping, signing and creating digital messages with .pfx certificates
  • Extracting font names from documents written in Cyrillic
  • Deconstructing cryptosmt tool - Ascon cipher – changing from 5 to 4 size s-box
  • Simulating cryptocurrency risk levels
  • Decrypting digital files using PGP private keys

By hiring a Cryptographer through Freelancer.com on your projects you can ensure that your data remains secure, be it for a simple encryption project or something more complex such as building secure communication networks between multiple users. If you have a project requiring specialist cryptographic support then post it today on Freelancer.com and hire one of our experts to bring your project to life.

    認証済み

    I need a full, production-ready fork of the open-source Signal project, re-architected as a set of container-friendly Go microservices. The goal is to keep the rock-solid end-to-end encryption that Signal offers while gaining the flexibility, horizontal scalability, and deployment speed that a Go-driven service mesh provides. Project Overview, We are building a next-generation secure communication platform based on the open-source Signal ecosystem. Our goal is to create a production-ready platform that supports millions of users while preserving Signal's proven end-to-end encryption. We are looking for senior engineers with experience in distributed systems, Go, Java, cloud infrastructure, and large-scale backed development. What do you want to add to…? Technology Stack &bul...

    KYA Cryptographic Middleware Development

    # Technical Specification: KYA (Know Your Agent) Cryptographic Middleware ## Objective We require a mid-to-senior backend developer to construct a secure "Know Your Agent" (KYA) verification middleware layer. The goal is to ensure our autonomous AI agents can execute API actions only after verifying their identity cryptographically against an anchored decentralized web3 domain (.u / .wif). ## Core Deliverables 1. **Verification Middleware:** Intercept incoming agent requests. Parse custom routing headers: `X-Agent-Domain` and `X-Agent-Signature`. 2. **Domain Resolution Adapter:** Integrate with Web3/DNS libraries to resolve the public key assigned to the agent's domain identity records. 3. **Cryptographic Validation:** Implement Ed25519 signature validation verifying the r...

    Polygon Lit Encryption Integration
    1 日 left

    I need to call Lit Protocol from the Polygon chain purely for data encryption and decryption, while signing every interaction with an ordinary Ether wallet—no dedicated Lit wallet should ever be required. Here is what I have in mind: • A minimal smart-contract setup on Polygon that can trigger Lit’s JS SDK for encrypting and later decrypting data. • Front-end or script examples that let me sign those calls with any standard EVM wallet (MetaMask, Trust Wallet, etc.) so long as the user never has to create or fund a Lit wallet. • Clear, step-by-step deployment notes so I can replicate the flow in testnet and mainnet, plus concise code comments referencing the Lit nodes, auth sig generation, and the specific Polygon RPC endpoints used. Acceptance criteri...
