Key Features
KeyChain application has evolved from the need of the Array.IO team to provide safe storage of the user identity when interacting with Array products. Array.IO is fully open-sourced and KeyChain couldn’t be anything less than that. Hence, the independent application for key storage we see as a public good for Web.3. KeyChain application is not related to any third-party wallet providers, exchanges and other services requiring signatures. KeyChain assures complete discreteness from the user client through three layers which interact with each other in a secured manner.
KeyChain encrypts private keys with AES256 algorithm and stores them in the isolated environment, protected with three security layers and a passphrase. API layer - integrates with your app, website or any external application. Security layer receives the commands from API layer and acts as an OS-specific protection mechanism for the secured passphrase entry. Representation layer is the UI window which notifies the user about the details of transactions and necessary actions. Once the user inputs the correct passphrase, it sends the permission to the Signing module to unlock the demanded key. Signing module can operate with the open private key, for example it can extract information, sign transactions, therefore responding to given requests. To sign a transaction, a user needs to unlock private keys and set the timeout during which he/she will be able to sign without a passphrase - but only within the same instance.
There are many options for the storage of ones private keys but the level of reliability on hardware and software solutions is the key metric users base their decision upon. KeyChain app serves one purpose - to safely store the keys and encrypt them so that only the local host has access to the actual key. Once the developer integrates his app/website with KeyChain, he directs the storage on the user’s desktop and KeyChain does the signing of any sequence of data with encrypted keys that are never displayed. Each time the user is required to provide the signature KeyChain initiates the process and interacts with the app through the given transport. Security layer of KeyChain ensures complete discreteness when it comes to the exchange of information between the user client and the key storage. There’s no third party involved in the process of signing transactions and interaction with the keys. Browser extensions and other similar hackable solutions are completely avoided.
KeyChain stands for easy-to-use, open-source, and supportive. To use KeyChain, all you need to do is install it and integrate with your project. It can be easily downloaded for Linux, MacOs and Windows. After installation developers can choose between two transport options of KeyChain integration - WebSockets and Pipe, which work with any client application. Managing KeyChain is a breeze - it is language neutral and allows you to stay loyal to the developer’s stack. Refer to our API documentation, guides, demos and examples broken down into sections.
