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.

# Project Requirement: Deep Learning Side-Channel Analysis Pipeline for 3DES Smartcards ## Project Overview We are seeking an experienced security engineer / machine learning specialist to update and correct an existing Deep Learning-based Side-Channel Analysis (SCA) pipeline for Triple-DES (3DES) smartcards. The current pipeline successfully recovers session keys from known-input traces but produces incorrect 3DES keys when applied to blind forensic traces, despite achieving 100% attack success rate. ## Background The existing pipeline implements a hypothesis-based profiling attack using Multi-Layer Perceptrons (MLP) to extract 3DES session keys (K_ENC, K_MAC, K_DEK) from electromagnetic traces. While the system achieves 100% recovery on standard datasets (Mastercard/Visa with...

We wanna create a private server for an MMORPG game and are wanna develop python client. The original game client is written in python and protected by CheatBlocker. The goal of this job is to reverse-engineer the client’s network layer to handle the handshake and encryption protocols. The game utilizes a hybrid encryption scheme: TEA for decryption and 3DES for encryption. We need a specialist to bridge the communication between our custom Python client and the game server. This project is strictly for private server development and protocol documentation. What We Need Protocol Analysis: Analyze the game client EXE using IDA Pro to locate the packet encryption and decryption routines. Handshake Reversal: Identify the logic behind the initial handshake process. You must extract h...
