The Master Key to Your Decentralized Vault. In a true zero-trust architecture, separating your encrypted payloads is only half the battle. The Cryptosign Citadel Medallion serves as the physical master encryption key required to decipher your Shamir Secret Sharing (SSS) shards.
Forged in a covert, military-spec dog tag format, this medallion allows you to keep the decryption key physically separated from the encrypted shares. Hide the shares across multiple geographic locations, and wear the Medallion or lock it in a separate vault to ensure absolute, offline asset control.
The Ultimate Physical OpSec
Cryptographic Master Key: Laser-engrave the master QR key or hex seed required to decipher your distributed SSS plates and terminal payloads.
Marine-Grade Durability: Forged from ultra-dense, 1.8mm thick 316L Stainless Steel, vastly superior to standard, paper-thin aluminum tags. Built to withstand severe mechanical crushing and industrial environments.
High-Density QR Ablation: The brushed steel surface is optimized for high-contrast laser engraving, ensuring your decryption key remains perfectly scannable by offline reader devices for generations.
Extreme Thermal Resistance: Engineered to withstand temperatures up to 1400°C (2550°F), easily surviving catastrophic house fires.
Corrosion & EMP Proof: Zero electronic components. 100% immune to electromagnetic pulses, saltwater corrosion, and chemical degradation.
