Cryptosteel Capsule is the premier backup tool for autonomous offline storage of valuable data without any third-party involvement. The solid metal device, designed to survive extreme conditions, works under nearly all circumstances. It is compatible with most secret sharing and key generation algorithms.
The Capsule offers more capacity than most other solutions in its class, while being smaller, lighter, and more durable. And it comes with a full ASCII character set (96, including space) supporting random passwords with numbers and symbols. All of the characters are deeply stamped into the tiles to provide maximum longevity.
