Hardware-Backed Secrets for Authorized Processes

A hardware-backed secrets manager that replaces plaintext secrets in configuration files with an encrypted store and a daemon-mediated access workflow. On macOS, access is gated by user presence and caller code-signature verification, so authorized processes can request secrets with the user's approval.

Security guarantees depend on the platform and key custodian. See the repository's security documentation for the threat model and limitations.

Key Features

  • •Encrypted, per-file secret storage managed by secretsd
  • •Hardware-backed key custodians including Secure Enclave, Keychain, and YubiKey
  • •User-presence checks and caller code-signature verification on macOS
  • •CLI for storing, retrieving, listing, and deleting secrets
  • •Inject selected secrets into a child process with secrets run

Proof of Exploit

Archived43

Zero-Knowledge Bug Bounty Proofs

Proof of Exploit enabled security researchers to prove knowledge of smart contract vulnerabilities without revealing the actual bug. Using zero-knowledge proofs built on zkEVM circuits, researchers could demonstrate that an exploit works and share cryptographic proof with bug bounty managers — all without disclosing vulnerability details.

Development discontinued — a core dependency (PSE/zkevm-circuits) is no longer maintained. Previously supported by Privacy and Scaling Explorations (PSE).

Key Features

  • •Write exploit, generate ZK proof, share without revealing the bug
  • •Challenge contract codehash revealed in public inputs; exploit contract stays hidden
  • •CLI with commands: exploit test, exploit prove, exploit verify
  • •Web-based proof verification at proofofexploit (verifier compiled to WASM)
  • •Proof storage via IPFS CIDs

Key Features

  • •Apple Watch integration with HealthKit for sleep tracking
  • •Smart contract-based commitment with automatic penalties
