Verifying Digital Signatures of Software Packages

To prevent a software package from being maliciously tampered with during transfer or storage, download also the corresponding digital signature file for integrity verification while downloading the software package.

After the software package is downloaded, verify its PGP digital signature by referring to the OpenPGP Signature Verification Guide. If the verification fails, do not use the software package, and contact Huawei technical support engineers.

Before a software package is used in installation or update, its digital signature also needs to be verified according to the OpenPGP Signature Verification Guide to ensure that the software package is not tampered with.
