# Verify the signature on RPM-based systems

Before installing the software, verify the software authenticity by validating the signature.

 
 

## Task

1. Log on to the system as a user with administrator rights.
2. Locate the public key (GPG) from the software download site.
3. Import your public key to your RPM DB using this command. 
  
 <kbd> rpm --import &lt;Public_Key_Name&gt;</kbd> 
  
  
 

If you don't import the public key using this command, you will get the following warning message during the installation.

 
 

<samp>/tmp/tmp.FdcQqEpF3i/McAfeeTP-&lt;vesion_number&gt;-&lt;build_number&gt;.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID &lt;key_number&gt;: NOKEY</samp>
4. Verify the signature. 
  
 <kbd>rpm -K McAfeeESP-&lt;version_number&gt;-&lt;build_number&gt;_x86_64.rpm</kbd> 
  
 <kbd> rpm -K McAfeeRt-&lt;version_number&gt;-&lt;build_number&gt;_x86_64.rpm</kbd> 
  
 <kbd>rpm -K McAfeeTP-&lt;version_number&gt;-&lt;build_number&gt;_x86_64.rpm</kbd> 
  
 <kbd>rpm -K McAfeeESPFileAccess-&lt;version_number&gt;-&lt;build_number&gt;_x86_64.rpm</kbd> 
  
 <kbd>rpm -K McAfeeESPAac-&lt;version_number-&lt;build-number&gt;-x86_64.rpm</kbd> 
  
 You get a message similar to 
 <kbd>McAfeeESP-&lt;version_number&gt;-&lt;build_number&gt;.x86_64.rpm: rsa sha1 (md5) pgp md5 OK</kbd>
