Registration Status Change” confirming that your registration status has changed. 

3.2 eSignature PIN Verification

Upon first logging into CDX after your DC FUEL role has been activated, you will be prompted 

to complete your eSignature PIN Verification. See Figure 3-1.

4.7 Submitting Reports from Different Computers

A user certificate and Private/Public Key pair is used to digitally sign and encrypt the submitted 

files, providing security protection for DC FUEL submissions. The certificate and key pair is

automatically obtained after the first DC FUEL login. 

The following data is stored into a keystore under your computer’s home directory: 

• user ID

• user private key

• user certificate

• creation time

The following file will be created: \<userHome>\ .<userId>-cromerr-keystore.jks where 

<userHome> is a local user home directory (C:\Documents and Settings\myuser) and <userId> is 

your DC FUEL user ID registered with CDX Web (i.e. DCFuelTest01-cromerr-keystore.jks). 

This file is stored on the local drive of the machine that was used to log into DC FUEL to 

complete a submission. While you may submit files from any machine, you will only be able to 

access the copy of records for the submitted documents from the specific machine for a 

submission unless the key file is copied into the same location of another machine. In any case, it 

is recommended that you copy this file to another safe location for backup.
