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.

    Project Overview: We are building a multi-tenant B2B SaaS platform that dynamically generates, signs, and distributes secure, encrypted data archives (.zip variants) based on user input. We are currently in stealth mode and will share specific business logic upon signing an NDA. Key Responsibilities: • Develop a multi-tenant backend engine that takes JSON inputs and assets from a relational database and compiles them into cryptographically signed file packages. • Implement secure cryptographic file signing workflows using server-side certificates (.p12/OpenSSL). • Build out a robust asynchronous worker queue to handle real-time HTTP/2 server-to-client push updates at scale. • Develop a responsive web dashboard for business configuration and a mobile-friendly web viewer ...

    I need an experienced digital forensics specialist to recover and restore my original encrypted iPhone 14 Pro backup. Problem: Original encrypted backup created on 18 June 2026, approximately 68 GB. On 25 June 2026, a subsequent backup overwrote the original backup metadata, including and associated files. Most original encrypted payload files appear to survive, but the original per-file encryption-key records are missing from the current manifest. The original backup password is available. Previous recovery attempts and forensic examinations have not restored the original backup. Required outcome: Recover the original backup data and make it usable for restoration, preferably through Apple Devices/iTunes. The objective is actual recovery of original files, not merely rebuilding metada...
