CreateCredFile utility

This topic describes the credential file, and the CreateCredFile utility that you use to create the credential file.

Overview

Components and applications that require automated access to the Digital Vault use a credential file that contains the user’s Vault username and encrypted logon information.

The credential file contains sensitive logon information, so it’s important to restrict access and usage as much as possible to reduce potential hijacking of the file.

 

Make sure that you are familiar with the user’s Vault authentication details, because you must provide the correct logon credentials to generate the encrypted credential file.

Supported authentication types

Password

For password authentication, the credential file contains a user with CyberArk authentication that authenticates to the Vault using a username and a password. You can also use the following external authentication types along with password authentication.

Asymmetric keys

You can create a credential file that contains a key-pair combination and the CyberArk user for authenticating to the Vault.

Additional protection mechanisms

HSM device

The credential file secret can be encrypted by a HSM device. This can be used for password authentication.

Any PKCS#11 library is supported as long as it meets all of the following criteria:

  • The token must be a hardware token.

  • The token is accessible through the PKCS#11 interface.

  • Access to the token is only possible after supplying a PIN.

  • The token supports RSA 2048-bit key length.

  • The token must be able to perform encryption and key generation on hardware.

  • A 32-bit .dll must be used (64-bit is not supported).

DPAPI

The credential file secret can be encrypted by the Windows DPAPI mechanism, which can be used for both password and key-pair (asymmetric keys) credential files. The DPAPI mechanism can be used with machine and user level protections either separately or together.

Credential file security

The credential file is protected using the following mechanisms:

  • The encrypted password is changed daily, by default.

  • The encrypted secret is encrypted using an AES 256-bit key that contains the following materials:

    • Random salt that is stored in the credential file (512-bit). This randomness assures that each credential file is encrypted with a unique key.

    • Environmental key materials:

      Material type

      Description

      Application-based

      Unique materials that identify the application in the logon process.

      Machine-based

      Unique materials that identify the machine in the logon process.

      Component-based

      Unique materials that identify the component in the logon process.

    • The key is generated by a secure hash (SHA2-512) comprised of the above key materials.

  • You can protect your credential file even more by using the appropriate operating system permissions.

Create a credential file

Use the CreateCredFile utility to create a credential file from a command line prompt. The CreateCredFile utility is located in the component/application installation folder.

You can run the CreateCredFile utility from the same machine where it will be used, or you can copy the credential file to the component or application host machine after it is created.

 

In order to comply with the strongest security guidelines, create the credential file on the same machine where it will be used - not on a remote server.

You must use a valid password for the user when you create the credential file. Before creating the credential file, verify the following:

  • The user must use the CyberArk authentication method.

  • You have the correct username for the user.

  • The user is not currently being used by an active component/application.

  • The user is not suspended on all Vaults (Primary and Satellite Vaults).

  • You have reset the password to a known password.

To create a credential file:

  • Open the command prompt as an Admin user, and run the CreateCredFile utility with the relevant flags set.

    The CreateCredFile utility uses the following syntax:

     

    CreateCredFile <FileName> <command> [command parameters]

    For more information about command usage, see CreateCredFile utility examples.

    The credential file is created and saved in the current folder or the folder that you specified in the command. The following message appears:

    Command ended successfully

 

If you perform any hardware changes on the machine such as adding or replacing a network card, graphic card, disk, or OS license, you must re-create the credential file.

CreateCredFile utility examples

The examples used in these instructions run the utility from the CreateCredFile subfolder, and create a credential file called user.cred.

  1. Open the command prompt as an admin user.

  2. Run the CreateCredFile.exe utility with all the relevant flags set.

    • Windows syntax:

      • Human user syntax with HSM device (recommended):

         

        CreateCredFile.exe user.cred Password /username <username> /password <password> /ExePath <path> /IpAddress /Hostname /OSUsername <domain\user> /EntropyFile /DpapiMachineProtection /HSMProtection /DLLpath <path\pkcs11-provider.dll> /PIN <pin code> /InitToken

        CreateCredFile.exe user.cred Password /username <username> /password <password> /ExePath <path> /IpAddress /Hostname /OSUsername <domain\user> /EntropyFile /DpapiMachineProtection /DpapiUserProtection

      • Component or application user syntax with HSM device (recommended):

         

        CreateCredFile.exe user.cred Password /username <username> /password <password> /ExePath <path> /IpAddress /ClientHostname /OSUsername <domain\user> /AppType <Application ID> /HSMProtection /DLLpath <path\pkcs11-provider.dll> /PIN <pin code> /InitToken

        CreateCredFile.exe user.cred Password /username <username> /password <password> /ExePath <path> /IpAddress /Hostname /OSUsername <domain\user> /AppType <Application ID /EntropyFile /DpapiMachineProtection /DpapiUserProtection

      • Human user syntax on a remote server:

         

        This method is less secure, and shouldn't be used in a production environment.
         

        CreateCredFile.exe user.cred Password /username <username> /password <password> /OSUsername <domain\user> /NotSecure

      • Component or application user syntax on a remote server:

         

        This method is less secure, and shouldn't be used in a production environment.
         

        CreateCredFile.exe user.cred Password /username <username> /password <password> /OSUsername <domain\user> /AppType <Application ID> /NotSecure

    • *NIX syntax:

      • Human user syntax:

         

        ./CreateCredFile user.cred password -username <username> -password <password> -exepath <path> -hostname -osusername <domain\user> -entropyfile

      • Component or application user syntax:

         

        ./CreateCredFile user.cred password -username <username> -password <password> -exepath <path> -hostname -osusername <domain\user> -entropyfile -apptype <Application ID>

      • Human user syntax on a remote server:

         

        This method is less secure, and shouldn't be used in a production environment.
          CreateCredFile user.cred password -username <username> -password <password> -osusername <user> -notsecure

      • Component or application user syntax on a remote server:

         

        This method is less secure, and shouldn't be used in a production environment.
          CreateCredFile user.cred password -username <username> -password <password> - osusername <user> -apptype <Application ID> -notsecure

         

 

To apply LDAP or RADIUS authentication or other configurations, see CreateCredFile parameters for more details.
 

Only use this option if instructed by CyberArk.

  1. At the command line prompt, run the CreateCredFile.exe utility.

     

    CreateCredFile.exe user.cred KeyPair /username <username> /ExePath <path> /IpAddress /Hostname /OSUsername <domain\user> /EntropyFile /DpapiMachineProtection /DpapiUserProtection

The above example creates a credential file with a generated encrypted private key.

 

Only use this option if instructed by CyberArk.

Using the Convert option allows you to upgrade the credential file version to the latest one but does not improve security. To improve security, you must create a new credential file.

After you upgrade to version 12.2 or later, if you log on using the existing credential file, the credential file will be automatically converted to the latest version (version 3).

To manually convert a credential file to the latest version, run the following command:

  1. At the command line prompt, run the CreateCredFile.exe utility.

     

    CreateCredFile.exe user.cred Convert /AppType <ApplicationID>/ExePath <path> /OSUsername <domain\user>
 

You must specify one or more of the following flags with the same values given in the original credential file:

  • /AppType

  • /OSUsername

  • /ExePath

The above example converts the user.cred file to the latest version, and renames the previous file to user.cred.old.
