Python / Hashcat Specialist Needed for Custom Dictionary & Password Pattern Recovery
Publicada el 2026-07-27
Descripción de la oferta
Overview: I am looking for an experienced developer/cryptography specialist to help recover a lost password using a provided hash file and targeted password lists. Task Details: I have extracted the hash from an old encrypted data file. I will provide a list of base words, usual patterns, numbers, and Pinyin combinations that were likely used. You will need to build custom masks/rules or run optimized scripts (using Hashcat, John the Ripper, or similar tools) to test variations of these patterns. Requirements: High experience with Hashcat, rule files, and custom mask creation. Access to high-performance GPU hardware for fast testing. Strong understanding of Pinyin and multi-language wordlist generation is a plus. Absolute confidentiality and willingness to work strictly within Upwork terms. Payment Terms (Success-Based): No upfront payment or hourly fee. This is a contingency-based project: You will receive a 25% commission of the total wallet balance upon successful recovery of the password. Payment will be released via Upwork Escrow once valid proof is provided and the wallet is successfully unlocked. No payment will be made if the recovery is unsuccessful. If you have experience running custom rule-based pattern recoveries and agree to these terms, please submit your proposal with a brief description of your GPU setup and experience.
