4.3 Verifying OpenPGP Signature (Linux)
This section describes how to verify the integrity of an obtained software package, thereby
preventing network risks that may be caused by malicious alteration or damage during the
transmission of the software package. A software package can be installed only after it passes
the verification.
Prerequisites
The GNU Privacy Guard (GnuPG) tool has been installed in the SUSE Linux operating
system.
Run the gpg --version command in the PuTTy. If the following information is displayed, the
GnuPG tool has been installed in the SUSE Linux operating system:
signsrv:~ # gpg --version
gpg (GnuPG) 2.0.9

Hash: MD5, SHA1, RIPEMD160, SHA256, SHA384, SHA512, SHA224
Compression: Uncompressed, ZIP, ZLIB, BZIP2
Used libraries: gcrypt(1.5.0)
signsrv:~ #
If the GnuPG tool has not been installed, you can download the GnuPG tool package from
http://www.gnupg.org/, and then install the GnuPG tool by following the instructions
provided in the website.
Context
The GnuPG is a free open-source GNU tool. It can be used to verify OpenPGP signatures in
the SUSE Linux operating system.
Procedure
Step 1 Obtain the signature file for the PowerEcho software package, and upload the signature file
through FileZilla to the directory for storing software packages to be verified on the
PowerEcho server.
A digital signature file can be named in the following format: name of a software
package+.asc. For example, the digital signature file of the NetEco server application is
iManager_NetEco_PowerEcho_V600R007C50SPC200.zip.asc.

The digital signature file of a software package coexists with the software package. When obtaining the
software package, you can click the
icon behind the software package to obtain its digital signature
file.
Step 2 Download the public key file.
Download the OpenPGP Signature Verification Guide package from
http://support.huawei.com/carrier/digitalSignatureAction, and then decompress the package to
obtain the public key file KEYS.
Step 3 Import the public key file.
1.
Use FileZilla to upload the KEYS file to the PowerEcho server.
You need to set the following information when you use FileZilla to upload the file:
−
User name and password: user ossuser and its password, For details, see Planning
Operating System Users and Their Initial Passwords in NetEco Product
Documentation.
−
Port: the default port for SFTP is port 22
−
Directory for storing the uploaded file: /export/ossuser
2.
Use PuTTY to log in to the PowerEcho server as user ossuser.
3.
Switch to user root.
> su - root
Password: root password
4.
Go to the directory for storing the KEYS file, and then import the KEYS file as user
root.
# cd /export/ossuser
# gpg --import "/export/ossuser/KEYS"
/export/ossuser indicates the directory for storing the signature file. You need to rename
the directory based on site conditions.
5.
Check whether the public key file is successfully imported.
# gpg --fingerprint
If the following information is displayed, the public key file is successfully imported:
pub 2048R/27A74824 2013-12-30
Key fingerprint = B100 0AC3 8C41 525A 19BD C087 99AD 81DF 27A7 4824
uid OpenPGP signature key for Huawei software (created on 30th
Dec,2013) <support@huawei.com>
Step 4 Verify the public key.
In normal cases, the validity of the OpenPGP public key needs to be verified according to the
ID, fingerprint, and user ID (uid) of the public key published by the involved entity. Huawei
publishes the following information about the OpenPGP public key:

Key ID: 27A74824

Key fingerprint: B100 0AC3 8C41 525A 19BD C087 99AD 81DF 27A7 4824

User ID (uid): OpenPGP signature key for Huawei software (created on 30th Dec,2013)
<support@huawei.com>
After the validity of the public key is verified, you can do as follows to set the trust level of
the public key:

/export/ossuser indicates the directory for storing the signature file. You need to rename the
directory based on site conditions.
iManager_NetEco_PowerEcho_V600R007C50SPC200.zip.asc indicates the name of the
signature file. You need to rename the file based on site conditions.
The following information is displayed, where the RSA key ID in bold is the same as the
public key ID (if no error message, such as WARNING, Key expired, Signature expired,
and Key is revoked is displayed for any other information, the signature is valid):

When signatures of multiple files need to be verified for a software package, the software package is
safe only when the verification results of all the files are PASS. If the verification result of any file is
WARNING or FAIL, the software package fails the verification, and security risks exist. If this occurs,
you need to re-download the software package.

4.4 Verifying OpenPGP Signature (Windows)
This section describes how to verify the integrity of an obtained software package, thereby
preventing network risks that may be caused by malicious alteration or damage during the
transmission of the software package. A software package can be installed only after it passes
the verification.
Prerequisites
You have obtained the signature file for the NetEco software package. The NetEco software
package and its signature file are in a one-to-one relationship, and are stored in the same
directory.
Context

The GNU Privacy Guard for Windows (Gpg4Win) is a free open-source GNU tool. It
can be used to verify OpenPGP signatures in the Windows operating system.

You can download the Gpg4Win software package used with the Windows operating
system from http://www.gpg4win.org/, and then double-click gpg4win-2.3.1.exe to
install the Gpg4Win tool by following the wizard. You are advised to retain all the
default settings during the installation.
Procedure
Step 1 Download the public key file.
Download the OpenPGP Signature Verification Guide package from
http://support.huawei.com/carrier/digitalSignatureAction, and then decompress the package to
obtain the public key file KEYS.
Step 2 Import the public key file.
1.
Log in to the server on which the software package to be verified is stored, and enter the
command-line interface (CLI).
2.
Go to the directory (for example, C:\Users\) for storing the KEYS file, and then import
the KEYS file.
> gpg --import "C:\Users\KEYS"
C:\Users\KEYS indicates the directory for storing the KEYS file. You need to rename
the directory based on site conditions.

Possible Cause
The security certificate of the PowerEcho is not issued by the trusted Certificate Authority
(CA). If the certificate is issued by the CA that Internet Explorer cannot identify, for example,
user-defined certificate, the certificate error message is displayed upon the login.
Procedure
1.
2.
Apply for a certificate from the CA, including NEPL_PKI.cer and
Huawei_Equipment_CA.cer
Import the certificates.
−
Choose Tools > Internet Options on the menu bar of Internet Explorer.
−
In the displayed Internet Options, click Content.
−
In the content tab, click Certificate.
−
Click Import, import the certificate following the guide.
3.
In the displayed Internet Options dialog box, click Advanced.
4.
In the Setting area, clear Warn about certificate address mismatch under Security.
5.
Click OK. The Internet Options dialog box is displayed.
6.
Restart Internet Explorer and re-log in to the PowerEcho.

Services of the PowerEcho are not affected when the certificate expires. Internet Explorer,
however, displays a warning dialog box saying The security certificate expired or has
not taken effect. Are you sure you want to continue?. Select Continue. The website
starts running properly and the connection is proper.

This problem can be resolved by upgrading the PowerEcho.
