Estimating the term…
A method for storing a cryptocurrency private key offline, including: encrypting the cryptocurrency private key using a primary encryption key; sharding the encrypted cryptocurrency private key into a plurality of alpha shards; generating beta shards by encrypting the alpha shards with secondary encryption keys; and storing representations of the beta shards offline. The method can additionally or alternatively include: retrieving the representations of the beta shards from the offline storage; decrypting the beta shards into the alpha shards based on the secondary encryption keys; reconstructing the encrypted cryptocurrency private key by recombining the alpha shards; and decrypting the encrypted cryptocurrency private key with the primary encryption key.
A method for offline storage of a cryptocurrency private key of a cryptocurrency public-private key pair for a cryptographic currency, the method comprising:
The method of claim ii, wherein determining alpha shards based on the set of secondary encryption keys comprises:
The method of claim ii, further comprising:
A method for cryptocurrency private key retrieval from offline storage, comprising:
