Revealer is a free software tool to encrypt your secrets visually.
Our first release is a seed backup plugin for the Electrum Wallet. It allows you to generate both shares and print them out yourself, or to type the code of a physical Revealer and encrypt your seeds or any arbitrary secret with it.
Like other encryption methods, the user has two factors that allow to create a redundancy while minimizing risk of compromise. Differently to usual encryption methods, the secret can be decrypted optically – without a computer or any special knowledge. This makes it specially useful for cold storage and inheritance planning.
Electrum Bitcoin Wallet comes with the Revealer Plugin.
Electrum was the first wallet to introduce a seed phrase concept (2011) and is one of the most advanced, flexible and simple to use Bitcoin wallet available. We are proud partners of Electrum and a percentage of our products sale goes to Electrum Technologies.
If you are running version Electrum 3.2 or newer you can activate the Revealer Plugin at ‘Tools-> Plugins’. Otherwise, download electrum from the official website https://electrum.org.
