Problems solved by technology

[0004] The present invention aims to propose a method for creating a blockchain address private key. Through the technical solution mentioned in the present invention, it can solve the problem of traditional passwords with few digits and low strength, which are easy to be cracked, original key characters are messy and meaningless, and difficult to remember. A series of problems such as the unreliability of the third-party custody center

Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted here that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute conflicts with each other.

[0030] Before the present invention is further described, some proper nouns involved in the present invention are briefly explained:

[0031] Secure Hash Algorithm: Secure Hash Algorithm SHA (Secure Hash Algorithm) is a series of cryptographic hash functions designed by the National Security Agency (NSA) and released by the National Institute of Standards and Technology (NIST), including SHA-1, SHA -224, SHA-256, SHA-384, and SHA-512 variants. It is mainly applicable to the digital signature algorithm (Digital Signature Algorithm DSA) defined in the digital signature standard (DigitalSignature Standard DSS), where t...

Abstract

The invention discloses a method for creating a block chain address private key, comprising the following steps of: firstly, selecting self-defined information as a seed by a user, and generating a unique identification feature through a sha256 algorithm; secondly, generating a public key and private key pair by taking the unique identification feature as an input condition of a sodium signature algorithm. The whole process is unidirectional and irreversible, and through the method, a series of problems that traditional passwords are few in digits, low in strength and easy to crack, original key characters are disordered, meaningless and difficult to remember, and a third-party storage center mechanism is unreliable can be solved; The encrypted data only exist on the block chain, the private key is not stored, and the unique identification feature and the user-defined information are not stored, so that the safety of the user account is better protected, and the confidentiality effectis really achieved.

Description

technical field [0001] The invention relates to the technical field of blockchain, in particular to a method for creating a private key of a blockchain address. Background technique [0002] The private key is the bottom line to guarantee the rights and interests of users. In most blockchains, each user has a pair of public key and private key. Since the characters of the private key are irregular and long, almost no users will directly remember this key. The private key is more often saved in the photo album in the form of a picture QR code, or directly stored by a third-party wallet service provider. This can obtain some direct benefits: First, it is saved in the form of a picture QR code to facilitate user transfer and safekeeping; second, the advantage of unified storage by the third-party wallet service provider is that users only need to remember the password set by the service provider. However, while obtaining these benefits, it also brings some hidden dangers: firs...
