Abstract
The present disclosure relates to off-line generation, storage, and usage of digital assets, such as cryptocurrency. In particular, methods and systems are disclosed for generating off-line cryptographic key pairs for the off-line storage of digital assets using storage techniques that do not involve connecting to the Internet. In one example, a method for generating off-line cryptographic key pairs includes receiving user input from a user, determining a key generation algorithm based on the user input, wherein the key generation algorithm relates to a digital asset, generating an off-line cryptographic key pair based on the user input and key generation algorithm, and outputting the off-line cryptographic key pair.
