# Verify the signature on RPM-based systems

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

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.

`rpm --import <Public_Key_Name>`

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

/tmp/tmp.FdcQqEpF3i/McAfeeTP-<vesion_number>-<build_number>.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID <key_number>: NOKEY
4. Verify the signature.

`rpm -K McAfeeESP-&lt;version_number&gt;-&lt;build_number&gt;_x86_64.rpm`

`rpm -K McAfeeRt-&lt;version_number&gt;-&lt;build_number&gt;_x86_64.rpm`

`rpm -K McAfeeTP-&lt;version_number&gt;-&lt;build_number&gt;_x86_64.rpm`

`rpm -K McAfeeESPFileAccess-&lt;version_number&gt;-&lt;build_number&gt;_x86_64.rpm`

`rpm -K McAfeeESPAac-&lt;version_number-&lt;build-number&gt;-x86_64.rpm`

You get a message similar to `McAfeeESP-&lt;version_number&gt;-&lt;build_number&gt;.x86_64.rpm: rsa sha1 (md5) pgp md5 OK`
