What is the SecureZIP Global Directory?
The SecureZIP Global Directory is a public LDAP directory, which stores the email addresses and certificates of users. These certificates can be used to exchange digitally signed and encrypted files and/or emails using SecureZIP®.
How do I get my certificate to upload?
Your certificate is available on the machine where your private key resides. You can export your certificate to a file and upload the certificate file using this request form. Complete this form and use the Browse button to locate your certificate file, then press "Submit request".
How do I export my certificate?

  2. Select the Content tab and select the Certificates button.
  3. Highlight your certificate in the list on the Personal tab and select Export to start the Windows Certificate Export Wizard.
  4. In the Wizard select, "No, do not export the private key" and select Next.
  5. Select 'DER encoded binary X.509 (.CER)' and select Next. Name the export file, select Next and then Finish to complete the Wizard.
After my certificate is in the Directory, how do others find it?
SecureZIP version 11.3 automatically locates certificates in the SecureZIP Global Directory. When securing email using SecureZIP, certificates in the directory will be used to encrypt messages and file attachments. Versions of SecureZIP Enterprise prior to 11.3 can be configured to use the global directory via the Certificate Stores tab under Security Options settings. Add a new store having a "Server" value of 'directory.comodo.com' with "Base" value of 'OU=directory, DC=comodo, DC=com.'
What if I get a new certificate?
If you get a new certificate, you can replace your current certificate in the directory by uploading a new certificate file at http://directory.comodo.com.
What if my certificate is compromised?
If your certificate is ever compromised, you should notify your Certificate Authority immediately to revoke your certificate and obtain a new certificate. Then remove your compromised certificate from the SecureZIP Global Directory by emailing a request to: pkwareroots@pkware.com.
How do I revoke my certificate?
If your certificate was not issued to you by the Comodo/PKWARE Secure Email CA you must contact your Certificate Authority for information on how to revoke your certificate. If your certificate was issued to you by the Comodo/PKWARE Secure Email CA, please visit Comodo Support to submit a ticket requesting your certificate be revoked.
How do I add a certificate with a private root?
Certificates from most publicly rooted Certificate Authorities (CA) can be added to the SecureZIP Global Directory. If your certificate is issued by a private CA such as may be provided by your company, or if your certificate cannot be inserted into the directory because your CA is not recognized, please contact PKWARE for information on how to add your root to the directory. Email your request to pkwareroots@pkware.com.
