Verifying Package Signatures

This section explains how to verify signatures of the CTE-U installer packages. After the signature is verified, CTE-U can be installed on file servers.

Verifying Signature of rpm Packages

To verify the signature of the rpm package:

1. Download the public key from the Support Portal:

   

   Note

   The key is named 610-000250-001_PUBLIC-GPG-CONNECTOR-SIGNING-KEY.key.

2. Save the key on the file server, for example, at /cte/public_key.

3. Navigate to the directory where the extracted CTE-U packages are stored.

4. Import the public key into the rpm keystore, type:

   Run rpm --import /path/to/public_key/<gpg_key>.

   Copy

   Example

   rpm --import /cte/public_key/610-000250-001_PUBLIC-GPG-CONNECTOR-SIGNING-KEY.key

   Copy

5. Verify the signature, type:

   rpm -Kvv <protectfile_installer>.rpm.

   Copy

   Example

   rpm Kvv cte_<version>-<build>.x86_64.rpm

   Copy

   The command output should contain information similar to the following:

   cte-<version>-<build>.x86_64.rpm:
   Header V3 RSA/SHA256 Signature, key ID <key_id>: OK
   Header SHA1 digest: OK (<sha1_digest>)
   V3 RSA/SHA256 Signature, key ID <key_id>: OK
   MD5 digest: OK (<md5_digest>)

   Copy

If the output contains Signature, key ID : OK for SHA256, the signature is verified successfully.

Verifying Signature of deb Packages

To verify the signature of the deb package:

1. Download the public key from the Support Portal:

   

   Note

   The key is named 610-000250-001_PUBLIC-GPG-CONNECTOR-SIGNING-KEY.key.

2. Save the key on the file server, for example, at /cte/public_key.

3. Navigate to the directory where the extracted CTE-U packages are stored.

4. Import the public key, type:

   gpg --import /path/to/public_key/<gpg_key>

   Copy

   For example, run:

   gpg --import /pf/public_key/610-000250-001_PUBLIC-GPG-CONNECTOR-SIGNING-KEY.key

   Copy

5. Verify the signature, type:

   gpg -verify cte_<version>-<build>.deb.sig.

   Copy

   If the output contains the text Good signature, the signature is verified successfully.

Verifying Signature of Interactive Installers

To verify the signature of the interactive installer package:

1. Download the public key from the Support Portal:

   

   Note

   The key is named 610-000250-001_PUBLIC-GPG-CONNECTOR-SIGNING-KEY.key.

2. Save the key on the file server, for example, at /cte/public_key.

3. Navigate to the directory where the extracted CTE-U packages are stored.

4. Import the public key, type: (The signature cannot be verified without a valid public key.)

   gpg --import /path/to/public_key/<gpg_key>.

   Copy

   For example, run:

   gpg --import /pf/public_key/610-000250-001_PUBLIC-GPG-CONNECTOR-SIGNING-KEY.key

   Copy

5. Verify the signature.

   gpg -verify safenet_pf<version>-<build>.tar.gz.sig.

   Copy

If the output contains a good signature, the signature is verified successfully.
