time-lock

Time-locked encryption vault with Dead Man's Switch. Send encrypted messages that unlock at a specific date or auto-release if you go silent. AES-256, split-key crypto, ephemeral seals. Perfect for crypto inheritance, whistleblowing, scheduled releases. Self-hostable.

A time-lock puzzle designed for browsers

A time-lock puzzle generator.

Steganographic storage & File encryption tool

Experimental memory-based cryptographic vault with deterministic password generation, zero-storage secrets, and time-lock protection.

TimeCipher is a blockchain-based time-locked messaging system that securely encrypts messages with a timestamp, ensuring they can only be decrypted after the specified time. This innovative solution combines privacy and delayed access, perfect for secure future communication.

Time-locked SOL savings dapp built with Ruby on Rails 8 — lock SOL, live countdown, unlock on expiry. Powered by SolRengine gems.

Node.js server implementation of the Time-Lock service provider based on decentralized systems

A lightweight library that lets developers store values that are only retrievable after a specified time. It acts like a “sealed envelope” or “time capsule” for objects, configs, or state.

TimeCapsule is a Solidity smart contract that enables users to store time-locked messages on the Ethereum blockchain. Create messages that can only be revealed after a specified time period, perfect for digital time capsules, future messages, or scheduled information releases.

A time-locked vault secured by cryptographic proof-of-work. Bury a secret; open it only when the math permits.
