Description

The Install-AdcsCertificationAuthority cmdlet performs installation and configuration of the Active Directory Certificate Services (AD CS) Certification Authority (CA) role service. To remove the certification authority role service use the Uninstall-AdcsCertificationAuthority cmdlet.

You can import the cmdlet by running the following commands from Windows PowerShell:

Install-WindowsFeature Adcs-Cert-Authority

To include the Certification Authority and Certificate Templates consoles in a CA installation, you must use the IncludeManagementTools parameter at the end of the Install-WindowsFeature Adcs-Cert-Authority command.

Int is equivalent to Int32 in the .NET Framework.

Examples

Example 1: Install a new Standalone Root CA with default settings

Install-AdcsCertificationAuthority -CAType StandaloneRootCa

This command installs a new Standalone Root CA with default settings.

Example 2: Install a new Enterprise Root CA using a specific provider and key length

$params = @{
    CAType             = EnterpriseRootCa
    CryptoProviderName = "ECDSA_P256#Microsoft Software Key Storage Provider"
    KeyLength          = 256
    HashAlgorithmName  = SHA256
}
Install-AdcsCertificationAuthority @params

This command installs a new Enterprise Root CA using the provider named ECDSA_P256 Microsoft Software Key Storage Provider, key length of 256, and the hash algorithm named SHA 256.

Example 3: Install a new Enterprise Root CA using a specific provider and a validity period

$params = @{
    CAType              = EnterpriseRootCa
    CryptoProviderName  = "RSA#Microsoft Software Key Storage Provider"
    KeyLength           = 2048
    HashAlgorithmName   = SHA1
    ValidityPeriod      = Years
    ValidityPeriodUnits = 3
}
Install-AdcsCertificationAuthority @params

This command installs a new Enterprise Root CA using the RSA algorithm using the provider named Microsoft Software Key Storage Provider, a key length of 2048, a hash algorithm named SHA 1, and validity period of three years.

Example 4: Install a new Enterprise Subordinate CA using a parent CA

$params = @{
    CAType   = EnterpriseSubordinateCa
    ParentCA = "SERVER75.corp.contoso.com\SERVER75-CA"
}
Install-AdcsCertificationAuthority @params

This command installs a new Enterprise subordinate CA, the parent CA is SERVER75 in the CORP domain of Contoso.com.

Example 5: Install a new Enterprise Subordinate CA using an existing certificate

$params = @{
    CAType           = EnterpriseSubordinateCa
    CertFile         = "C:\Cert\SERVER80-CA.p12"
    CertFilePassword = (Read-Host "Set user password" -AsSecureString)
}
Install-AdcsCertificationAuthority @params

This command installs an Enterprise Subordinate CA using an existing certificate from a PFX/P12 file that is located on the local C:\Cert folder named SERVER80-CA.p12.

Notes

Ensure you run Windows PowerShell as an administrator. You can use the force parameter to bypass the prompt for confirmation. To see parameters, run the following command:
```
`Install-AdcsCertificationAuthority -?`
```
If you have installation issues, try using the verbose parameter to get verbose output and review the information in the %windir%\cerocm.log file.
