First time using the AWS CLI? See the User Guide for help getting started.

Note: You are viewing the documentation for an older major version of the AWS CLI (version 1).

AWS CLI version 2, the latest major version of AWS CLI, is now stable and recommended for general use. To view this page for the AWS CLI version 2, click here. For more information see the AWS CLI version 2 installation instructions and migration guide.

[ aws . acm-pca ]



Creates a root or subordinate private certificate authority (CA). You must specify the CA configuration, the certificate revocation list (CRL) configuration, the CA type, and an optional idempotency token to avoid accidental creation of multiple CAs. The CA configuration specifies the name of the algorithm and key size to be used to create the CA private key, the type of signing algorithm that the CA uses, and X.500 subject information. The CRL configuration specifies the CRL expiration period in days (the validity period of the CRL), the Amazon S3 bucket that will contain the CRL, and a CNAME alias for the S3 bucket that is included in certificates issued by the CA. If successful, this action returns the Amazon Resource Name (ARN) of the CA.

ACM Private CAA assets that are stored in Amazon S3 can be protected with encryption. For more information, see Encrypting Your CRLs .


Both PCA and the IAM principal must have permission to write to the S3 bucket that you specify. If the IAM principal making the call does not have permission to write to the bucket, then an exception is thrown. For more information, see Configure Access to ACM Private CA .

--certificate-authority-configuration (structure)

Name and bit size of the private key algorithm, the name of the signing algorithm, and X.500 certificate subject information.

KeyAlgorithm -> (string)

Type of the public key algorithm and size, in bits, of the key pair that your CA creates when it issues a certificate. When you create a subordinate CA, you must use a key algorithm supported by the parent CA.

SigningAlgorithm -> (string)

Name of the algorithm your private CA uses to sign certificate requests.

This parameter should not be confused with the SigningAlgorithm parameter used to sign certificates when they are issued.

Subject -> (structure)

Structure that contains X.500 distinguished name information for your private CA.

Country -> (string)

Two-digit code that specifies the country in which the certificate subject located.

Organization -> (string)

Legal name of the organization with which the certificate subject is affiliated.

OrganizationalUnit -> (string)

A subdivision or unit of the organization (such as sales or finance) with which the certificate subject is affiliated.

DistinguishedNameQualifier -> (string)

Disambiguating information for the certificate subject.

State -> (string)

State in which the subject of the certificate is located.

CommonName -> (string)

Fully qualified domain name (FQDN) associated with the certificate subject.

SerialNumber -> (string)

The certificate serial number.

Locality -> (string)

The locality (such as a city or town) in which the certificate subject is located.

Title -> (string)

A title such as Mr. or Ms., which is pre-pended to the name to refer formally to the certificate subject.

Surname -> (string)

Family name. In the US and the UK, for example, the surname of an individual is ordered last. In Asian cultures the surname is typically ordered first.

GivenName -> (string)

First name.

Initials -> (string)

Concatenation that typically contains the first letter of the GivenName , the first letter of the middle name if one exists, and the first letter of the SurName .

Pseudonym -> (string)

Typically a shortened version of a longer GivenName . For example, Jonathan is often shortened to John. Elizabeth is often shortened to Beth, Liz, or Eliza.

GenerationQualifier -> (string)

Typically a qualifier appended to the name of an individual. Examples include Jr. for junior, Sr. for senior, and III for third.

--revocation-configuration (structure)

Contains a Boolean value that you can use to enable a certification revocation list (CRL) for the CA, the name of the S3 bucket to which ACM Private CA will write the CRL, and an optional CNAME alias that you can use to hide the name of your bucket in the CRL Distribution Points extension of your CA certificate. For more information, see the CrlConfiguration structure.

CrlConfiguration -> (structure)

Configuration of the certificate revocation list (CRL), if any, maintained by your private CA.

Enabled -> (boolean)

Boolean value that specifies whether certificate revocation lists (CRLs) are enabled. You can use this value to enable certificate revocation for a new CA when you call the CreateCertificateAuthority action or for an existing CA when you call the UpdateCertificateAuthority action.

ExpirationInDays -> (integer)

Number of days until a certificate expires.

CustomCname -> (string)

Name inserted into the certificate CRL Distribution Points extension that enables the use of an alias for the CRL distribution point. Use this value if you don't want the name of your S3 bucket to be public.

S3BucketName -> (string)

Name of the S3 bucket that contains the CRL. If you do not provide a value for the CustomCname argument, the name of your S3 bucket is placed into the CRL Distribution Points extension of the issued certificate. You can change the name of your bucket by calling the UpdateCertificateAuthority action. You must specify a bucket policy that allows ACM Private CA to write the CRL to your bucket.

JSON Syntax:

  "CrlConfiguration": {
    "Enabled": true|false,
    "ExpirationInDays": integer,
    "CustomCname": "string",
    "S3BucketName": "string"

--certificate-authority-type (string)

The type of the certificate authority.

Possible values:

  • ROOT

--idempotency-token (string)

Alphanumeric string that can be used to distinguish between calls to CreateCertificateAuthority . For a given token, ACM Private CA creates exactly one CA. If you issue a subsequent call using the same token, ACM Private CA returns the ARN of the existing CA and takes no further action. If you change the idempotency token across multiple calls, ACM Private CA creates a unique CA for each unique token.

--tags (list)

Key-value pairs that will be attached to the new private CA. You can associate up to 50 tags with a private CA. For information using tags with IAM to manage permissions, see Controlling Access Using IAM Tags .


Tags are labels that you can use to identify and organize your private CAs. Each tag consists of a key and an optional value. You can associate up to 50 tags with a private CA. To add one or more tags to a private CA, call the TagCertificateAuthority action. To remove a tag, call the UntagCertificateAuthority action.

Key -> (string)

Key (name) of the tag.

Value -> (string)

Value of the tag.

Shorthand Syntax:

Key=string,Value=string ...

JSON Syntax:

    "Key": "string",
    "Value": "string"

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.


To create a private certificate authority

The following create-certificate-authority command creates a private certificate authority in your AWS account.

aws acm-pca create-certificate-authority --certificate-authority-configuration file://C:\ca_config.txt --revocation-configuration file://C:\revoke_config.txt --certificate-authority-type "SUBORDINATE" --idempotency-token 98256344


CertificateAuthorityArn -> (string)

If successful, the Amazon Resource Name (ARN) of the certificate authority (CA). This is of the form:

``arn:aws:acm-pca:region :account :certificate-authority/12345678-1234-1234-1234-123456789012 `` .
