Decrypt Progressive Cipher Puzzle
Budget: $128 – $512 USD
I’m sitting on data (Text and .xls - other formats available) that hides a message in a video game. All previous digging suggests the text was encoded with a per-message progressive body cipher—possibly the GAK or XGAK variant—but I’ve hit a wall on how to pry it open. Distribution is flat with strong isomorph indicators. Messages seem to be in sets of three based on the isomorph overlap. Strong indicator for position 2+3 as the universal header.
What I need most now is clear, methodical guidance on the decryption process itself. If you’ve cracked progressive ciphers before, walk me through the workflow you’d apply, point out any traps unique to GAK/XGAK, and show how to verify each intermediate step so the final plaintext is undeniably correct.
Deliverables
• A repeatable breakdown of the decryption method (script, notebook or concise write-up)
• The fully decoded message, accompanied by a brief validation of its integrity
• Notes on any patterns or anomalies uncovered along the way
Please highlight relevant cipher-breaking experience in your bid; that’s the main factor I’ll use when choosing whom to work with.
