What is Fractum?

Fractum is designed for organizations and individuals who need to securely store critical information. It provides enterprise-grade cold storage with mathematical guarantees, eliminating single points of failure through distributed secret sharing. A robust long-term backup solution that combines AES-256-GCM encryption with Shamir's mathematically proven secret sharing. Protect your most critical assets—crypto wallets, SSH keys, passwords, and sensitive documents—with information-theoretic security designed for safe long-term storage.

💼 High-Value Use Cases:

  • Cryptocurrency wallet protection: Seed phrases, private keys, hardware wallet backups
  • Backup encryption master keys: Protect your backup infrastructure encryption keys
  • Root CA private keys: Certificate authority and PKI infrastructure protection
  • Emergency recovery credentials: Admin passwords, break-glass access credentials
  • Password manager exports: LastPass, Bitwarden, KeePass backup files
  • Legal & financial documents: Wills, contracts, tax records, insurance papers

🛠? Distributed Architecture Benefits:

  • Bus Factor Protection: Write a Will and instructions for family members - they can pool shares to recover your assets
  • Theft/Loss Protection: House fire, kidnapping/hostage situations, or lost hardware wallet - shares remain secure because you cannot be forced to access distant physical locations immediately
  • Geographic distribution: Store shares across multiple locations (family, friends, safe deposit boxes)
  • No single point of failure: Distributed trust across shares with threshold cryptography
  • Zero-knowledge property: K-1 shares reveal absolutely nothing about your secrets

🛡 Enterprise Security Features:

  • Works completely offline: perfect for air-gapped environments
  • Memory protection: Secure deletion and swap prevention
  • FIPS 140-2 compatible: Uses industry-standard algorithms
  • Container-native: Docker with security hardening and non-root execution
