What Armory is
Armory is a free, open-source Bitcoin wallet for generating and storing private keys. Its cold-storage setup keeps key data on an offline computer while an online watching-only wallet monitors payments and prepares transactions. The transaction process starts online, moves offline for signing, then returns online for broadcasting. Armory also supports distributed multi-signature addresses through Lockboxes, multiple wallets, key importing and sweeping, message signing, one-time printable backups, and GPU-resistant encryption. The download page lists version 0.96.0 for 64-bit Windows and Ubuntu/Debian, and version 0.95.1 for 64-bit Mac OS X; the homepage says updates in August 2026 made it usable as an iOS app. Armory provides signed hash files and GPG instructions for installer verification. Users control their keys and are responsible for protecting their bitcoins. Support resources include a FAQ, troubleshooting material, public forums, and a support portal.
