Abstract

The embodiment of the invention discloses an IPFS file encryption and decryption method and device and a medium. The method comprises the steps that a corresponding secret key is generated for a target IPFS file according to a preset first encryption algorithm; encrypting a target IPFS file by adopting the first encryption algorithm and a key to obtain a target ciphertext file; encrypting the secret key by adopting a preset second encryption algorithm, and determining an encrypted secret key; and packaging the first encryption algorithm, the second encryption algorithm, the encrypted key and a target ciphertext file into an encrypted object file, and storing the object file in an IPFS system. Reading a pre-generated encrypted object file, and determining a first encryption algorithm, a second encryption algorithm, an encrypted key and a target ciphertext file; decrypting the encrypted secret key by adopting the second encryption algorithm, and determining the secret key; and by taking the key as a parameter, decrypting the target ciphertext file by adopting the first encryption algorithm, and determining the target IPFS file.

Description

technical field [0001] This specification relates to the technical field of computers, and in particular to an IPFS file encryption and decryption method, device and medium. Background technique [0002] IPFS is a completely open system that anyone can store and access freely. Through the big data analysis and mining of the namespace and the files in it, it is likely to leak trade secrets. In a business practice environment, a more secure and confidential storage environment is required. [0003] There is a lack of solutions related to the confidentiality of IPFS files in the prior art, and a method for confidentiality of related IPFS files is now needed. Contents of the invention [0004] One or more embodiments of this specification provide an IPFS file encryption and decryption method, device, and medium to solve the following technical problem: there is a lack of solutions related to the confidentiality of IPFS files in the prior art. [0005] In order to solve the ...
