Problems solved by technology

[0004] In order to overcome at least to a certain extent the storage of electronic contracts on the blockchain is usually stored in plain text, which is not conducive to protecting the security of contract data information. Although some electronic contracts are signed after the contract information is encrypted, a fixed key is used. At the same time, storing the key in a computer or server is still easy to be leaked, and there is a problem of insecurity. This application provides an electronic contract data encryption storage method and a signing client

Embodiment Construction

[0042] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0043] figure 1 It is a flow chart of an electronic contract data encryption storage method provided by an embodiment of the present application.

[0044] Such as figure 1 As shown, the method of the present embodiment includes:

[0045] S11: Obtain contract documents from the bottom layer of the blockchain;

[0046] S12: Generate the original hash value according to the contract file;

[0047] The original hash value is generated according to the contract content in the contract file, because the content of each contract file is different, so each original hash value will also be different.

[0048] As an optional implementation of the present invention, the generating the original hash value according to the contract file includes: encrypting the contract file using the SHA-512 algorithm to generate the original hash value.

[0049] SHA (Secure...

Abstract

The invention relates to an electronic contract data encryption storage method and an electronic contract signing client. The electronic contract data encryption storage method comprises the steps ofobtaining a contract file from a block chain bottom layer; generating an original hash value according to the contract file; generating an encryption key according to the original hash value; uploading the encryption key to a block chain for storage; acquiring the encryption key from the block chain, and encrypting the data in the contract file by using the encryption key; and uploading the data in the encrypted contract file to a block chain for storage. The encryption key is not easily tampered, potential safety hazards of an electronic contract are eliminated, the original hash value is encrypted, and the security of the encryption key is further enhanced, so that the security of contract data information is more favorably protected.

Description

technical field [0001] This application relates to the field of Internet technology, in particular to an electronic contract data encryption storage method and a signing client. Background technique [0002] In recent years, electronic contracts have been widely used by people because of their advantages of convenient storage and not easy to lose. Traditional electronic contracts are mainly centralized storage, that is, electronic contracts are stored centrally in one or more servers. However, this centralized storage method makes the cylinder easy to be maliciously tampered with. [0003] In related technologies, electronic contracts are stored in the blockchain, but these electronic contracts are usually stored in plain text on the blockchain, which is not conducive to protecting the security of contract data information. Although some electronic contracts are signed, the contract information is Encryption, using a fixed key and storing the key in a computer or server, is...
