Cryptosteel is the premier indestructible backup tool for optimal offline storage of private keys, passwords and wallet recovery seeds without any third-party involvement.
You can think of Cryptosteel as the master of all backups. A safe deposit box for your virtual valuables. The one artifact you can hold in your hand that actually protects your digital assets. The DIY equivalent of engraving—which is the most proven and reliable method of storing information invented to date.

Cryptosteel comes with more than 250 stainless steel letter tiles engraved on each side. Codes and passwords are assembled manually from the supplied part-randomized set of tiles. Users are able to store up to 96 characters worth of confidential information in minutes, guaranteeing safety of the data with no need for specialized tools or third-party involvement.
Once a desired sequence is locked into the Cryptosteel unit, it essentially gains the status of offline permanence, featuring resistance to physical damage, including fire, flooding, corrosive conditions and impact from accidents.

Cryptosteel can store all your private sensitive data, regardless of format. Examples include any of the following, as well as all other alphanumeric information you wish to store in an indestructible manner. Master passwords to your password manager (e.g. LastPass, KeePass, 1Password)

Bitcoin private keys in BIP39 format
Insurance account numbers
Bank account info and passwords
GPS coordinates
Poems and haiku
Rainbow Codes
Elliptic curve coordinates
Stuff we haven’t even thought of yet

The beauty of the BIP39 format and the Cryptosteel backup solution is that you only need to store and access the first 4 letters of each word. These 4-letter sequences are unique and sufficient to recover the full sentence and thus the entire bitcoin wallet. We have frequency analysis data backing up that 96 is the minimum number of letters necessary and sufficient for optimal wallet recovery seed security.

With Cryptosteel, your most sensitive information is both hacker-proof and safe from the elements. There is no third party involved in keeping your recovery seed safe. And Cryptosteel beats paper, wood and corrosive metals in terms of durability. Unlike space-age materials, however, it is affordable, non-toxic and hard to detect using next-gen methods of surveillance.
