Abstract: Disclosed are a key management method and a key management apparatus. The method includes: after confirming that a user logs into a digital identity through a first identity authentication mode, acquiring a first character decryption key corresponding to a first character in at least one character of the digital identity; and decrypting, based on the first character decryption key, an encrypted target key stored in the digital identity to obtain a target key, where the target key is used to manage an asset corresponding to the first character. Based on the technical solutions provided in the present application, a user can log into a digital identity through existing identity information and implement asset management without memorizing a cumbersome and complicated key, which provides great convenience for the user.

Abstract: Disclosed are a key management method and a key management apparatus, where the key management method includes: acquiring authorization of a user through a first identity authentication mode to generate a first authentication encryption key, where the first identity authentication mode is used for logging into a digital identity; and encrypting at least one character decryption key by using the first authentication encryption key to obtain at least one initially encrypted character decryption key corresponding to the first identity authentication mode, where the at least one character decryption key is in a one-to-one correspondence with at least one character of the digital identity and used to decrypt at least one encrypted target key to obtain at least one target key. In the technical solutions of the present application, an identity authentication mode can be associated with a target key, facilitating a management and use process of the target key.
