certutil

Caution

Certutil isn't recommended to be used in any production code and doesn't provide any guarantees of live site support or application compatibilities. It's a tool utilized by developers and IT administrators to view certificate content information on devices.

Certutil.exe is a command-line program installed as part of Certificate Services. You can use certutil.exe to display certification authority (CA) configuration information, configure Certificate Services, and back up and restore CA components. The program also verifies certificates, key pairs, and certificate chains.

If certutil is run on a certification authority without other parameters, it displays the current certification authority configuration. If certutil is run on a non-certification authority without other parameters, the command defaults to running the certutil -dump command. Not all versions of certutil provide all of the parameters and options that this document describes. You can see the choices that your version of certutil provides by running certutil -? or certutil <parameter> -?.

Tip

To see complete help for all certutil verbs and options, including ones that are hidden from the -? argument, run certutil -v -uSAGE. The uSAGE switch is case-sensitive.

Note

Performance issues are observed when using the -store parameter given these two aspects:

When the number of certificates in the store exceeds 10.
When a CertId is specified, it's used to match all the listed types for every certificate. For example, if a serial number is provided, it will also attempt to match all other listed types.

If you are concerned about performance issues, PowerShell commands are recommended where it will only match the specified certificate type.

Tip

The ability to specify an Active Directory Domain Services (AD DS) domain [Domain] and to specify a domain controller (-dc) was added in Windows Server 2012. To successfully run the command, you must use an account that is a member of Domain Admins or Enterprise Admins. The behavior modifications of this command are as follows:

If a domain is not specified and a specific domain controller is not specified, this option returns a list of domain controllers to process from the default domain controller.
If a domain is not specified, but a domain controller is specified, a report of the certificates on the specified domain controller is generated.
If a domain is specified, but a domain controller is not specified, a list of domain controllers is generated along with reports on the certificates for each domain controller in the list.
If the domain and domain controller are specified, a list of domain controllers is generated from the targeted domain controller. A report of the certificates for each domain controller in the list is also generated.

For example, assume there is a domain named CPANDL with a domain controller named CPANDL-DC1. You can run the following command to a retrieve a list of domain controllers and their certificates from CPANDL-DC1: certutil -dc cpandl-dc1 -DCInfo cpandl.

If a string value starts with + or -, and the existing value is a REG_MULTI_SZ value, the string is added to or removed from the existing registry value. To force creation of a REG_MULTI_SZ value, add \n to the end of the string value.
If the value starts with \@, the rest of the value is the name of the file containing the hexadecimal text representation of a binary value.
If it doesn't refer to a valid file, it's instead parsed as [Date][+|-][dd:hh] which is an optional date plus or minus optional days and hours.
If both are specified, use a plus sign (+) or minus sign (-) separator. Use now+dd:hh for a date relative to the current time.
Use i64 as a suffix to create a REG_QWORD value.
Use chain\chaincacheresyncfiletime @now to effectively flush cached CRLs.

Imports user keys and certificates into the server database for key archival.

certutil [options] -importKMS UserKeyAndCertFile [CertId]

Where:

UserKeyAndCertFile is a data file with user private keys and certificates that are to be archived. This file can be:
- An Exchange Key Management Server (KMS) export file.
- A PFX file.
CertId is a KMS export file decryption certificate match token. For more information, see the -store parameter in this article.
-f imports certificates not issued by the Certificate Authority.

Options:

[-f] [-Silent] [-split] [-config Machine\CAName] [-p Password] [-symkeyalg SymmetricKeyAlgorithm[,KeyLength]]

-ImportCert

Imports a certificate file into the database.

certutil [options] -ImportCert Certfile [ExistingRow]

Where:

ExistingRow imports the certificate in place of a pending request for the same key.
-f imports certificates not issued by the Certificate Authority.

Options:

[-f] [-config Machine\CAName]

Remarks

The Certificate Authority may also need to be configured to support foreign certificates by running certutil -setreg ca\KRAFlags +KRAF_ENABLEFOREIGN.

-GetKey

Retrieves an archived private key recovery blob, generates a recovery script, or recovers archived keys.

certutil [options] -GetKey SearchToken [RecoveryBlobOutFile]
certutil [options] -GetKey SearchToken script OutputScriptFile
certutil [options] -GetKey SearchToken retrieve | recover OutputFileBaseName

Where:

script generates a script to retrieve and recover keys (default behavior if multiple matching recovery candidates are found, or if the output file isn't specified).
retrieve retrieves one or more Key Recovery Blobs (default behavior if exactly one matching recovery candidate is found, and if the output file is specified). Using this option truncates any extension and appends the certificate-specific string and the .rec extension for each key recovery blob. Each file contains a certificate chain and an associated private key, still encrypted to one or more Key Recovery Agent certificates.
recover retrieves and recovers private keys in one step (requires Key Recovery Agent certificates and private keys). Using this option truncates any extension and appends the .p12 extension. Each file contains the recovered certificate chains and associated private keys, stored as a PFX file.
SearchToken selects the keys and certificates to be recovered, including:
- Certificate Common Name
- Certificate Serial Number
- Certificate SHA-1 hash (thumbprint)
- Certificate KeyId SHA-1 hash (Subject Key Identifier)
- Requester Name (domain\user)
- UPN (user@domain)
RecoveryBlobOutFile outputs a file with a certificate chain and an associated private key, still encrypted to one or more Key Recovery Agent certificates.
OutputScriptFile outputs a file with a batch script to retrieve and recover private keys.
OutputFileBaseName outputs a file base name.

Options:

[-f] [-UnicodeText] [-Silent] [-config Machine\CAName] [-p Password] [-ProtectTo SAMNameAndSIDList] [-csp Provider]

Remarks

For retrieve, any extension is truncated and a certificate-specific string and the .rec extensions are appended for each key recovery blob. Each file contains a certificate chain and an associated private key, still encrypted to one or more Key Recovery Agent certificates.
For recover, any extension is truncated and the .p12 extension is appended. Contains the recovered certificate chains and associated private keys, stored as a PFX file.
