Cryptographic key management systems configured to provide key management services for the secure and decentralized control and storage of private cryptographic keys and other information. Asset private keys, seeds, passphrases, and other digitized information may be split into a plurality of subkeys and distributed to a group of people to allow the group to gain control of the asset private key if and when a specified condition has occurred. In some examples, the group of people receive less than a threshold number of the subkeys required to restore the asset private key and one or more of the subkeys required to restore the asset private key are defined as validator subkeys, the validator subkeys separately and securely stored. In some examples, the validator subkeys are encrypted and the encrypted validator subkeys stored on a blockchain platform.

The present disclosure relates to methods and systems for cryptographic private key management for secure multiparty storage and delivery of information. The encryption key management system is configured to provide key management services for secure and decentralized control and storage of private encryption keys and other information. The asset private key, seed, passcode, and other digitized information may be split into multiple subkeys and distributed to a group of people to allow the group to take control of the asset private key when specified conditions occur. In some examples, the group of people receives less than a threshold number of subkeys required to recover the asset private key, and one or more subkeys required to recover the asset private key are defined as verifier subkeys, which are separately and securely stored. In some examples, the verifier subkey is encrypted and the encrypted verifier subkey is stored on the blockchain platform.
