Overview

OSCCA-published cryptographic algorithms are cryptographic technologies and products used for the encryption or authentication of information that does not involve state secrets.

OSCCA-published cryptographic algorithms are independent and controllable algorithms developed by the State Cryptography Administration. They can improve the encryption strength and encryption and decryption performance. OSCCA-published cryptographic algorithms meet the requirements of government agencies, public institutions, large state-owned enterprises, financial banks, and other industries for reconstruction.

Huawei Cloud BCS provides the OSCCA-published cryptographic algorithm SDKs for you to develop client programs while protecting your private keys.

Downloading Resources

Table 1 SDK list

Matching Hyperledger Fabric Version

Language

Link

Fabric v1.4.0 and Fabric v2.2

Go

Go to the BCS console and click Use Cases. Download Fabric_SDK_Go.

Java

Go to the BCS console and choose Interactive Walkthroughs > Use Cases. Download Fabric_SDK_Gateway_Java or Fabric_SDK_Java.
NOTE:
  • The Go version must be v1.12 or later but must be earlier than v1.16.
  • The OSCCA-published cryptographic algorithm SDKs offer all functions of common SDKs and additionally support the OSCCA-published cryptographic algorithms.
  • Fabric_SDK_Gateway_Java encapsulates some interfaces of the SDK, covering Fabric_SDK_Java and making it easier to use. Therefore, Fabric_SDK_Gateway_Java is recommended.

After decompressing the downloaded package, you will obtain the directories listed in the following table.
