Basic constraints

The basic constraints parameter allows you to define the basic constraints extensions.

Example JSON: Basic constraints

Includes basic constraints in the certificate

{ 
  ...
  "extensions": {
    "basic_constraints": {
      "include": "yes",
      "ca": true
      "path_length": 2
    }
  }
}

Do not include basic constraints in the certificate

{
  ...
  "extensions": {
    "basic_constraints": {
      "include": "no"
    }
  }
}

Parameters: Basic constraints

Description

basic_constraints

object

optional

Basic constraint details

.. include

string

optional

Define if basic constraints are included in the certificate.

Possible values:

  • yes (default): include basic constraints in the certificate

  • no: do not include basic constraints in the certificate

.. ca

boolean

optional

If false, the certificate is not a certificate authority (CA) certificate.

If true, the certificate is a CA certificate.

If set to true:

  • CA certificate must have this feature enabled on it and must be a private issuer CA certificate

  • The key_usage extension will be set automatically, so the certificate template must not include any key_usage values. Any key_usage value included in the certificate template will cause the certificate template to be rejected.

.. path_length

integer

optional

Sets the pathLenConstraint in the ≥basic_constraints. Only use if ca is set to true. If ca is set to false, this value is ignored.

Possible values:

  • 0 (default): include the field and set path length to zero

  • -1:exclude the field from the certificate and do not set path length

  • > 0: include the field in the certificate and set the path length to an integer greater than 0
