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.

    Building a Machine Learning Model for Game Here's a step-by-step guide to building a machine-learning model for the game, including code examples and resource recommendations: Step 1: Data Collection and Preprocessing Collect Hashes: Gather as many hashes as possible from the game. Consider recording the steps taken within the game to generate each hash. Analyze Hash Format: Determine the format of the hashes (e.g., length, character types, presence of delimiters). This helps choose appropriate algorithms for processing and analysis. Clean and Preprocess Data: Clean the data by removing duplicates, handling missing values, and ensuring consistent format. Standardize the data if necessary. Step 2: Model Selection and Architecture Design Choose Machine Learning Algorithm: Based on t...
