The SDK of Huawei Cloud Low Latency Live (LLL) encapsulates REST APIs provided by LLL to simplify development. You can directly call API functions provided by the LLL SDK to use LLL. For details about how to download and integrate the client SDK and use APIs, see Table 1.

NOTICE:

Currently, LLL supports only SDK access, not signaling access.

**Table 1** Client SDK
Client	SDK Download	Version	Developed By	Function	SDK Reference	API Reference
Web	SDK: HWLLS_SDK_Web_2.10.9.tar.gz Integrity check: HWLLS_SDK_Web_2.10.9.tar.gz.sha256	2.10.9	Huawei Cloud	LLL functions	Web SDK Reference	Web API Reference

Checking Software Package Integrity

Check the integrity of downloaded SDK packages, that is, check whether the packages are tampered with or packets are lost during download.

The procedure is as follows:

Download the SDK package and its integrity verification SHA-256 package in Table 1 to the local PC.
Open the local CLI and run the following command to generate the SHA-256 value of the downloaded SDK package on the local PC.
In the following command, D:\HWLLS_SDK_Web_2.6.0.tar.gz indicates the local path for storing the SDK package and the SDK package name. Change it as needed.
```
certutil -hashfile D:\HWLLS_SDK_Web_2.6.0.tar.gz SHA256
```
Example command output:
```
D:\HWLLS_SDK_Web_2.6.0.tar.gz hash of SHA-256:
3ac83be852e8dcc9e90f236801fd4c494983073543e1ae66ee4d0c29043dccd1
CertUtil: -hashfile Command executed.
```
Compare the SHA-256 value of the downloaded SDK package with that of the queried SDK package.

If they are the same, no tampering or packet loss occurred during download.
