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

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 phy
