Descriptor overview
The engine’s descriptors are the following:
...
Each descriptor is described in detail in the sections below, including requirements how it shall be bootstrapped.
Certain descriptors are used for optional features. If a certain feature (for example email signing) is not used in a given deployment, then you may configure the descriptor in question with a placeholder. Any PKCS#12 file containing a self-signed keypair will be sufficient in this case.

Signing and verification of the object history
...
Placeholder allowed only if history verification is disabled (via
activitiHistoryCleanerJobTrigger.cronExpressionset to a date in the distant future. See List of Identity Manager system properties and Quartz CronTrigger tutorial for more information)Integrity of history signature would be as risk
Re-signing requires use of the batch_re-sign_history tool once the first history entry is created
If you plan on enabling it at a later date, it is recommended not to use a placeholder

Send signed e-mails emails from IDM
Required
When e-mail email signing is configured
Configured in the following application
...
Placeholders allowed only if email signing is not used
Email verification will fail if not issued by a trusted S/MIME CA
Integrity of e-mails emails sent by IDM may be at risk if placeholder key is used
...
Proper S/MIME certificate with configured IDM e-mail email sender address in DN's E field and/or SAN RFC-822 entry
If subject DN email field is absent, SAN extension must be critical
Note: broken Broken support for DN.E was is fixed in IDM 245.0.0.R1
must not be self-signed
Key usage:
If present, must be critical and at least either digitalSignature or nonRepudiationValidity:

Certificate requirements
Must not be self-signed!
Key usage is not checked (recommended for informational purposes: set digitalSignature)
Issuing CA cert must be trusted by the app onto which to provision Visual IDs
Validity: at your discretion (make sure you do not forget to renew before the expiry date!), validity is checked on the SDK side
Versioning not needed (always uses the default (i.e. that is, highest) version)
Misc Attestation Key Descriptors (att_…)

Descriptors included in default configuration. Correct bootstrapping may be required for productive use, depending on the use case. Replacement of the default certificates is optional. |
...
att_external-attestation-1 (mobile only)
att_external-attestation-2 (mobile only)
att_external-attestation-3 (mobile only)
att_external-attestation-4 (mobile only)
att_ATTESTATION (mobile+desktop, default)
Use
...
case
Verify Certification Signing Requests (CSR) from Smart ID Mobile/Smart ID Desktop App.
Optionally limit profile provisioning with Smart ID Mobile/Smart ID Desktop App to certain devices, for example company devices. This can be done by using Mobile/Desktop apps with custom private keys and configuring the corresponding public keys into IDM in Identity Manager (by default IDM Identity Manager includes certificates for the built-in keys of any Mobile and Desktop App installation)
...
Default certificates do not need to be changed, unless you want to limit profile provisioning to certain devices
No private keys is configured for IDMIdentity Manager, only each public key inside a certificate

Descriptor not present by default, can be ignored unless the Idopte middleware is used for PKI card production. |

case
Initial handshake with Idopte client-side middleware, see Encoding using Idopte middleware in Identity Manager
Configured in the following application
...
Idopte webapp cert, issued by Idopte based on CSR for a customer-generated keypair
One customer-specific SAN URI (does not have to point to an existing website), e.g. for example https://idopte.customer.com (using hosts like localhost or 127.x.y.z is discouraged, as it severely restricts the maximum validity period of the certificate Idopte can issue)
Validity: defined by the Idopte CA
