Method and device for developing and manufacturing block chain common cryptography algorithm SDK (Software Development Kit)

Abstract

The invention belongs to the technical field of block chain-cryptography and security, and discloses a method and a device for developing and manufacturing a block chain common cryptography algorithm SDK (Software Development Kit), and the method comprises the steps that a block chain common algorithm is selected to design an API (Application Program Interface); proper parameters and specific working processes are determined; re-packaging is carried out based on an openssl library, a consistent and stable static library is statically compiled by utilizing the cross-platform characteristic of the openssl library, and a cross-platform SDK package is realized; the designed API interface and serial port communication and Bluetooth communication capable of transmitting large files are redeveloped, realized and burnt. The invention provides a very simple, very stable and cross-multi-platform SDK and development framework, realizes secure storage and calculation isolation of information such as a secret key on a physical level, can greatly facilitate development and use of various users, is widely applied to various scenes such as hardware encryption wallets in the field of block chains, and contributions are made to popularization of the block chain technology.

Description

technical field [0001] The invention belongs to the field of block chain-cryptography and security technology, and in particular relates to a method and device for developing and manufacturing SDK packages of cryptographic algorithms commonly used in block chains. Background technique [0002] At present, with the vigorous development of blockchain technology, especially its application in digital currency and other aspects, the most basic various cryptographic algorithms in its technical system have gradually entered the daily life of the present invention. [0003] Each block in the blockchain will store some transaction information and account information, etc. These data are encrypted and generated based on the hash algorithm, and the chain structure and mining mechanism of the blockchain are also closely related to the hash algorithm. In addition, the blockchain determines the owner of the data on the chain through public key encryption, and verifies the identity of the...

AI Technical Summary

Problems solved by technology

[0005] Through the above analysis, the existing problems and defects of the existing technology are: the existing open source cryptographic algorithm library lacks common algorithm sub-libraries for blockchain technology, and libraries that can cross platforms are too complicated and inconvenient to use, while convenient Simple libraries cannot be cross-platform, and the ease of use and the number of cross-platforms are not satisfactory

[0006] The difficulty of solving the above problems and defects is: it is difficult to design a cross-platform development framework, it is difficult to ensure stability and compatibility, and it is even more difficult to quickly gain market recognition and put into application

The purely self-developed SDK package is difficult to quickly gain market recognition in terms of security and stability, and requires a lot of testing and time-testing
