In fact, this is the major difference between easyDCP KDM Generator and easyDCP KDM Generator+.

While easyDCP KDM Generator can be used to issue KDMs for DCPs created and encrypted by yourself using easyDCP Creator+, easyDCP KDM Generator+ can also be used to generate KDMs for DCP that have been created by a third party mastering station.

Just like easyDCP Player+, easyDCP KDM Generator+ also allows you to export its own public certificate. Provide this certificate containing your public key to the content owner so they can issue a Distribution KDM (DKDM) to your easyDCP KDM Generator+ installation.
You can load this DKDM into easyDCP KDM Generator+ and generate new KDMs for other recipients from it. The new KDMs time windows have to be completely covered by the DKDMs time window.

easyDCP Creator+ is bundled with a tool called easyDCP KDM Generator. A demo version of easyDCP KDM Generator is included in the easyDCP Creator+ trial version.

easyDCP KDM Generator generates Interop- and SMPTE-compliant KDM files for DCPs created with easyDCP Creator+.

easyDCP KDM Generator has a separate manual that explains the procedure in more detail.

A full commercial version of easyDCP KDM Generator is part of the easyDCP Creator+ product.

Please note: easyDCP KDM Generator is not upgradable to easyDCP KDM Generator+

Easier & faster KDM creation:

Create KDMs for several cinemas using easyDCP KDM Generator+


Imagine the following situation:

  • Your encrypted DCP incl. activation key (easyDCP-Digest / DKDM) has already been completed.
  • Now many KDMs are to be generated as a group (e.g., all KDMs for a distribution area) so that they subsequently e.g. can be sent by e-mail to the cinemas.
  • Generating should be done quickly as a mass processing, easily and without time-consuming or faulty manual re-sorting.



  • Also works in the standard version of the easyDCP KDM Generator.
  • Warning: Do not manually change the filename of the server certificates or KDMs as they will not be able to be assigned in the cinema.

To create KDMs sorted by cinema screens in a tree structure, proceed as follows:

  1. First sort your server certificates once outside of easyDCP in a tree structure, e.g. by distribution area (here: "Distribution Area 1"):
  2. Now start the easyDCP KDM Generator +. First, drag the easyDCP Digest or the DKDM into the field "easyDCP Digest / DKDM". Then simply drag the folder that contains the subfolders with the sorted server certificates into the Server Certificates / Folder field:
  3. Now activate the options "Options> Replicate easyDCP Digest / DKDM Folder Structure" and "Recursive":
  4. 4. Finally enter the target directory under "KDM Output Folder" and start the mass generation by clicking on "Generate KDM (s)". The KDM Generator now creates all KDMs and places them in the same structure as the server certificates:

The KDMs can now be conveniently processed and e.g. be sent by e-mail to the cinemas.

Please note:
This template was created with easyDCP KDM Generator + Version 1.4.411. Previous versions may not yet include this feature, but newer versions may run slightly differently.

easyDCP Creator+ generates a proprietary DCP digest file along with each encrypted DCP.
This digest file contains all track files keys used for the encryption during the DCP creation process. Whenever one wants to generate KDMs, you can load this digest file into a separate tool called easyDCP KDM Generator.

easyDCP KDM Generator is included in each purchase of easyDCP Creator+.
All you need to do is collect your recipient´s public server certificates and put them into a local folder. Use only the "cert.sha256" files. Usually, they have either a *.crt or *.pem suffix.
In easyDCP KDM Generator, you merely need to load the digest file, point to the folder with the server certificates and specify the start and end dates of the KDMs validity period.

Upon clicking the "Generate" button, easyDCP KDM Generator will create KDMs for all server certificates in a single batch job. Please note, that a digest file may contain multiple compositions, but a KDM only ever contains keys for a single composition. Thus, easyDCP KDM Generator will create x KDMs.

For more details, please refer to the http://www.easydcp.com/sync/manuals/easyDCP_KDM_Generator_User_Manual.pdf.

easyDCP applications require different kinds of certificates

Server Certificates:

Is required to be able to receive KDMs. If a partner wants to send you an encrypted DCP, they will need your public server certificate so that they can issue a DKDM for. 

Signer Certificate:

Will be used to digitally sign content of encrypted DCPs or KDMs. Generally, all DCPs should be digitally signed to ensure that they will be ingested without any problems into a digital cinema server. Only for unencryted DCPs with Interop conformity, a signature is optional.


Which easyDCP application needs which certificates?

How you get your Signer- and Server- certificate?

From easyDCP Player 2.0.X, easyDCP Creator 2.2.X and easyDCP KDM Generator 1.4.15 

During „License & Certificate Request“ and activation via webshop www.easydcp.com Signer- and Server Certificates will be provided in "License & Certificate".

What kind of certificate are required, if at all, depends on the easyDCP application.

Older easyDCP versions

Please use license status on www.easydcp.com: New server certificate/manage certificate


How I can access to my previous Signer- and Server Certificates?

Please use license status on www.easydcp.com: Manage certificates
This option is available for customers with valid service extension


  • If you update to a newer easyDCP version, previous certificates should be maintained. When filling in a new license & certificate request, you will be prompted to enter the password that protects your current certificate. If the password can be verified, the new request will contain information, that you don´t need a new certificate.
  • Server certificates are bound to the hardware via the system hash. If you migrate to another system, you always need new server certificates.
  • Signer certificates are bound to a person rather than to a system.  However, each " License and Certificate set" contains a new signer certificate for technical reasons.

Please note: Every "Certificate Request" will be secured with a password specified by you.

You select the password when you fill in the request and will be prompted to enter it again, whey you import the License & Certificate Set and whenever a KDM is accessed. 

The password cannot be recovered!

A Distribution KDM (DKDM) is technically identical to a regular KDM.

The difference is that it targets another mastering station instead of a cinema server.
You can generate a DKDM with easyDCP KDM Generator. The procedure is identical to generating a regular KDM.

The other way around is also possible with easyDCP. Your distributor can generate a DKDM to your easyDCP Player+ or easyDCP Creator+ public certificate (they each have theire own certificate). easyDCP Player+ or easyDCP Creator+ are then able to open the encrypted DCP.

Starting with version easyDCP Player+ 1.3 the DCP can be exported and loaded into easyDCP Creator.

This is explained in the section: I have an existing DCP. Is there a way to import the DCP into easyDCP Creator?".
Please check also: I have an existing DCP. Is there a way to import the DCP into easyDCP Suite?

The newest easyDCP KDM Generator version 1.4.15 offers a simple support for TDL (Trusted Device List) for e.g. double projection in KDMs.

If a TDL for KDM is required, you only need to import the corresponding projector Certificates in the field " Trusted Device List" available at easyDCP KDM Generator 1.4.15  "Advanced Settings".

 pic1Beginning with version 2.1, easyDCP Creator+ is capable of opening encrypted DCPs and using these DCPs as basis for new DCPs. There are basically two ways of providing the keys in order to allow easyDCP Creator+ to decrypt the content for the preview and for generating a new DCP.

If keys are provided by means of a proprietary Fraunhofer Digest file (*.dcpdig), it is assumed that the user generated the content and that he is in charge of the sources used for the original DCP generation. In this case you can alter all properties in easyDCP Creator+, including the deactivation of the encryption or the generation of a new encrypted DCP and Digest file.

 pic2If one provides the keys by means of Distribution KDM (or KDM), easyDCP Creator+ does not allow to disable the encryption nor does it generate the Fraunhofer Digest for the new DCP. In order to understand this behavior we have to explain that the Fraunhofer Digest stores the encryption key as plain text on the hard drive. If the Digest-option were not disabled, one could easily open an encrypted DCP together with a (D)KDM, generate a new encrypted DCP and store the encryption keys in plaintext. Since content-owners are very diligent with their content, Fraunhofer IIS decided to disable the option from the beginning.

Since the software does not permit you to generate a Digest, there has to be another way for communicating the encryption keys to another software. Using easyDCP Creator+ version 2.1 or higher this can be done by generating a (D)KDM directly from within easyDCP Creator+. The “Generate DCP…” dialog was extended to offer you to generate KDMs. By design, one (D)KDM will be generated for easyDCP Creator+ itself in order to make sure that one can open the DCP on the same computer using easyDCP Creator+ later. A second (D)KDM can be generated for another software being able to open (D)KDMs, including easyDCP KDM Generator+ and many other 3rd party hard-/and software tools.

DKDMs are used for the exchange of encrypted DCPs between postproduction houses. Processing DKDMs needs the same operation and security requirements that are used in the creation and operation of KDMs for the digital cinema.
easyDCP Creator+ enables to encrypt digital cinema content and the standard accessory easyDCP KDM Generator generates KDMs and DKDMs for the transfer of digital cinema content to postproduction houses or cinemas.

For further information please refer to:

For automatic generating and distribution of KDMs the online service KDM Studio is available at www.dcptools.com. 
KDM Studio is developed by the DCPtools Team based on easyDCP KDM Gnerator+.

Please notice that one can only generate one DKDM when generating a new DCP.

Usually, on the cinema server manufacturers' FTP servers you can find both the public server certificates and the signature chain that were used to sign the certificates.

If you decide to trust the certificate by examining the signature chain, you only need the server certificate to create a KDM. The server certificate usually has either a *.pem or a *.crt suffix.

easyDCP KDM Generator will accept either, but do not use both.

Furthermore, there may be pairs of certificate and chain that state "mpeg", "sha1" and "sha256".
Like with DCPs, there are SMPTE ("sha256") and Interop ("sha1" / "mpeg") KDMs.

Almost all modern cinema servers prefer SMPTE KDMs - even for Interop DCPs. So mostly the "sha256" version is used.

Only if you surely know your recipient only accepts Interop KDMs, use the "sha1" certificate and remember to check the "Enable Interop mode" option in the easyDCP KDM Generator's options tab.

Please see also: Where can I get the server certificates needed to create the KDMs?

If the customer decides for a service subscription the service extendes for another 6 month automatically if the customer has not completed the subscription at the latest 30 days before the end of the last renewal.

In case a customer decided not to prolong the support and no new version of specific software has been released, it is still possible to get back into normal service. Here a service fee of 50% (calculated form the regular service fee) for the period between previous service and the date the client wants to get back into support has to be paid. 

If a new version of specific software has been released during a non-supported period, no prolongation of the (expired) service is possible anymore. New: Here clients have to purchase a onetime fee in order to get the latest version of the easyDCP software. The update price depends on the date when the previous service extension has ended and the date the client purchased the update for his respective easyDCP application. The younger the last license the lower the update fee. Updates comes without automatic prolongation of service extension.

From now on, you will receive a discount on your service and support fees if you extend the service during the ongoing service period.

This is how it works: Since 2017-01-01 you receive a COUPON code on your bill for your next purchase of service extension. This voucher reduces your costs for the next service renewal of the same license by 10%.

The COUPON code is valid for the respective license from the issue of the invoice until the day on which your existing service expires. The date of the last validity is displayed in the COUPON.

How to use this voucher code:

NOTE: Your ongoing service must still be valid

  1. Go to your license status as usual
  2. Extend your existing service by at least 6 months.
  3. In checkout, the option "ADD COUPON" will be offered.
  4. Enter the individual coupon code for this license.

You will automatically receive a discount of 10%. The new service is automatically added to the end of the current service period. The invoice now contains a new COUPON code in order to receive a 10% discount for the next renewal.

Hint: You can spare yourself the manual entry of the voucher code by signing up for a subscription, which automatically extends the service in time. You then receive the discount without entering a COPUON code.

The procedure is different in every country. We can't send you the certificates.

  • The best way is to ask the cinema owners directly. They should have current certificates of their projection systems in their screening rooms or tell you the model and serial number.
  • Another idea is to contact the server vendors directly.
  • If you have the model and serial number, you can contact the manufacturer and ask for access to their database.
