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.

    Smart and Secure Point of Sale Framework with Threat Modeling and Formal Verification Existing PoS (Point of Sale) based payment frameworks are vulnerable as the Payment Application’s integrity in the smart phone and PoS are compromised, vulnerable to reverse engineering attacks. In addition to these existing PoS (Point of Sale) based payment frameworks do not perform point-to-point encryption and do not ensure communication security. We propose a Smart and Secure PoS (SSPoS) Framework which overcomes these attacks. Our proposed SSPoS framework ensures point-to-point encryption (P2PE), Application hardening and Application wrapping. SSPoS framework overcomes repackaging attacks. SSPoS framework has very less communication and computation cost. SSPoS framework also addresses Heartble...

    I'm seeking a qualified individual or a team with expertise in AI and cybersecurity to conduct a red team and blue team simulation. This simulation should primarily focus on: - Testing the effectiveness of my existing firewall configurations - Uncovering any possible weaknesses with the highest accuracy Proficiency in AI simulation and blockchain security is a key requirement for this project. Alongside, hands-on experience with firewall testing and strong attention to detail will be crucial. The simulation's purpose is to push my defenses to the limit and reveal the slightest vulnerabilities that could potentially be exploited. So, a prior exposure to intricate simulations will be a significant add-on. The decisive factor here is not speed, but the depth and precision of vulne...

    I need to decrypt a crypted client-side log file (.txt) of a desktop application The goal is to understand the logic behind encryption and write a simple script that translates data in human-readable text. I have no idea on how encryption is made. The application has a client-server architecture, and could have restrictions based on user location. So, you will likely need to use a vpn or vps to test. Source code must be delivered at the end of contract, better if logic behind script is directly explained via call (not mandatory). Preferred language for scripts is p1ton (volutanry wrong to not received automated answers), but I am open to other language if there are clear benefits.
