CreateCertificateAuthority

Creates a root or subordinate private certificate authority (CA). You must specify the CA configuration, an optional configuration for Online Certificate Status Protocol (OCSP) and/or a certificate revocation list (CRL), 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 OCSP configuration can optionally specify a custom URL for the OCSP responder. 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.

Note

Both AWS Private CA 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 Access policies for CRLs in Amazon S3.

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

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

CertificateAuthorityConfiguration

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

Type: CertificateAuthorityConfiguration object

Required: Yes

CertificateAuthorityType

The type of the certificate authority.

Type: String

Valid Values: ROOT | SUBORDINATE

Required: Yes

IdempotencyToken

Custom string that can be used to distinguish between calls to the CreateCertificateAuthority action. Idempotency tokens for CreateCertificateAuthority time out after five minutes. Therefore, if you call CreateCertificateAuthority multiple times with the same idempotency token within five minutes, AWS Private CA recognizes that you are requesting only certificate authority and will issue only one. If you change the idempotency token for each call, AWS Private CA recognizes that you are requesting multiple certificate authorities.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 36.

Pattern: [\u0009\u000A\u000D\u0020-\u00FF]*

Required: No

KeyStorageSecurityStandard

Specifies a cryptographic key management compliance standard used for handling CA keys.

Default: FIPS_140_2_LEVEL_3_OR_HIGHER

Note

Some AWS Regions do not support the default. When creating a CA in these Regions, you must provide FIPS_140_2_LEVEL_2_OR_HIGHER as the argument for KeyStorageSecurityStandard. Failure to do this results in an InvalidArgsException with the message, "A certificate authority cannot be created in this region with the specified security standard."

For information about security standard support in various Regions, see Storage and security compliance of AWS Private CA private keys.

Type: String

Valid Values: FIPS_140_2_LEVEL_2_OR_HIGHER | FIPS_140_2_LEVEL_3_OR_HIGHER | CCPC_LEVEL_1_OR_HIGHER

Required: No

RevocationConfiguration

Contains information to enable support for Online Certificate Status Protocol (OCSP), certificate revocation list (CRL), both protocols, or neither. By default, both certificate validation mechanisms are disabled.

The following requirements apply to revocation configurations.

A configuration disabling CRLs or OCSP must contain only the Enabled=False parameter, and will fail if other parameters such as CustomCname or ExpirationInDays are included.
In a CRL configuration, the S3BucketName parameter must conform to Amazon S3 bucket naming rules.
A configuration containing a custom Canonical Name (CNAME) parameter for CRLs or OCSP must conform to RFC2396 restrictions on the use of special characters in a CNAME.
In a CRL or OCSP configuration, the value of a CNAME parameter must not include a protocol prefix such as "http://" or "https://".

For more information, see the OcspConfiguration and CrlConfiguration types.

Type: RevocationConfiguration object

Required: No

Tags

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.

Type: Array of Tag objects

Array Members: Minimum number of 1 item. Maximum number of 50 items.

Required: No

UsageMode

Specifies whether the CA issues general-purpose certificates that typically require a revocation mechanism, or short-lived certificates that may optionally omit revocation because they expire quickly. Short-lived certificate validity is limited to seven days.

The default value is GENERAL_PURPOSE.

Type: String

Valid Values: GENERAL_PURPOSE | SHORT_LIVED_CERTIFICATE

Required: No

Response Syntax


{
   "CertificateAuthorityArn": "string"
}

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

CertificateAuthorityArn

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.

Type: String

Length Constraints: Minimum length of 5. Maximum length of 200.

Pattern: arn:[\w+=/,.@-]+:acm-pca:[\w+=/,.@-]*:[0-9]*:[\w+=,.@-]+(/[\w+=,.@-]+)*

Errors

For information about the errors that are common to all actions, see Common Errors.

InvalidArgsException

One or more of the specified arguments was not valid.

HTTP Status Code: 400

InvalidPolicyException

The resource policy is invalid or is missing a required statement. For general information about IAM policy and statement structure, see Overview of JSON Policies.

HTTP Status Code: 400

InvalidTagException

The tag associated with the CA is not valid. The invalid argument is contained in the message field.

HTTP Status Code: 400

LimitExceededException

An AWS Private CA quota has been exceeded. See the exception message returned to determine the quota that was exceeded.

HTTP Status Code: 400
