The 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.

Our solution combines the age-old idea of engraving – in a DIY assembly format – with material that is stainless, shockproof, acid-resistant and fireproof up to 1400C/2500F. It is compatible with most secret sharing and key generation algorithms, and keeps the enclosed data secure. Even in cases of aggressive acts such as theft, bribery, vandalism or violence your master secret can remain safe forever.

There is no third party involved in keeping your data safe. And our metal capsule beats paper, wood, and corrosive metals in terms of durability. It is affordable, non-toxic, and hard to detect using next-gen methods of surveillance.

With Cryptosteel, your most sensitive information is both hacker-proof and safe from natural disasters.
