Verifying Software Package Integrity

To prevent software packages from being maliciously tampered with during transfer or storage, download also the corresponding digital signature files for integrity verification while downloading the software packages from the Kunpeng community.

Obtain the digital certificate and software package.
For details, see Table 1.
Obtain the OpenPGP Signature Verification Guide.
- For carriers: https://support.huawei.com/carrier/digitalSignatureAction.
- For enterprises, visit https://support.huawei.com/enterprise/en/tool/pgp-verify-TL1000000054.
Based on the OpenPGP Signature Verification Guide obtained in 2, verify the PGP digital signatures of the software packages.

If the verification fails, do not use the software packages. Contact Huawei technical support.

Before using a software package for an installation or upgrade, verify its digital signature by following instructions provided in the OpenPGP Signature Verification Guide to ensure that the software package is not tampered with.
