About:
ssss is a command-line implementation of Shamir's secret sharing scheme. It splits a secret (like an encryption key or password) into multiple shares, where a defined threshold of shares is required to reconstruct the original secret. This ensures that the secret remains secure even if some shares are compromised or lost.
Key Features:
  • Threshold-based splitting and reconstruction
  • Cryptographic integrity checks via polynomial interpolation
  • ASCII armor support for safe text-based storage
  • Hexadecimal and base64 encoding options
Use Cases:
  • Distributing encryption keys among multiple custodians
  • Securely storing wallet seeds across different physical locations
  • Creating fault-tolerant backup systems for critical credentials
Alternatives:
  • ssss-compat – Homebrew mirror of the original ssss package, largely identical functionality
  • shamir-secret-sharing – Modern Rust-based implementation with similar cryptographic primitives
