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

This parameter should not be confused with the SigningAlgorithm parameter used to sign certificates when they are issued.
Structure that contains X.500 distinguished name information for your private CA.

Contains information to enable Online Certificate Status Protocol (OCSP) support, to enable a certificate revocation list (CRL), to enable both, or to enable neither. The default is for both certificate validation mechanisms to be disabled.
Note
The following requirements apply to revocation configurations.
Enabled=False parameter, and will fail if other parameters such as CustomCname or ExpirationInDays are included.S3BucketName parameter must conform to Amazon S3 bucket naming rules.For more information, see the OcspConfiguration and CrlConfiguration types.
Configuration of the certificate revocation list (CRL), if any, maintained by your private CA. A CRL is typically updated approximately 30 minutes after a certificate is revoked. If for any reason a CRL update fails, Amazon Web Services Private CA makes further attempts every 15 minutes.
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.
Validity period of the CRL in days.
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.
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 operation. You must specify a bucket policy that allows Amazon Web Services Private CA to write the CRL to your bucket.
Note
The S3BucketName parameter must conform to the S3 bucket naming rules.
Determines whether the CRL will be publicly readable or privately held in the CRL Amazon S3 bucket. If you choose PUBLIC_READ, the CRL will be accessible over the public internet. If you choose BUCKET_OWNER_FULL_CONTROL, only the owner of the CRL S3 bucket can access the CRL, and your PKI clients may need an alternative method of access.
If no value is specified, the default is PUBLIC_READ .
Note: This default can cause CA creation to fail in some circumstances. If you have have enabled the Block Public Access (BPA) feature in your S3 account, then you must specify the value of this parameter asBUCKET_OWNER_FULL_CONTROL, and not doing so results in an error. If you have disabled BPA in S3, then you can specify eitherBUCKET_OWNER_FULL_CONTROLorPUBLIC_READas the value.
For more information, see Blocking public access to the S3 bucket.
Configuration of Online Certificate Status Protocol (OCSP) support, if any, maintained by your private CA. When you revoke a certificate, OCSP responses may take up to 60 minutes to reflect the new status.
Flag enabling use of the Online Certificate Status Protocol (OCSP) for validating certificate revocation status.
By default, Amazon Web Services Private CA injects an Amazon Web Services domain into certificates being validated by the Online Certificate Status Protocol (OCSP). A customer can alternatively use this object to define a CNAME specifying a customized OCSP domain.
Note
The content of a Canonical Name (CNAME) record must conform to RFC2396 restrictions on the use of special characters in URIs. Additionally, the value of the CNAME must not include a protocol prefix such as "http://" or "https://".
For more information, see Customizing Online Certificate Status Protocol (OCSP) in the Amazon Web Services Private Certificate Authority User Guide .
[REQUIRED]
The type of the certificate authority.
Specifies a cryptographic key management compliance standard used for handling CA keys.
Default: FIPS_140_2_LEVEL_3_OR_HIGHER
Note:FIPS_140_2_LEVEL_3_OR_HIGHERis not supported in the following Regions:
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."
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 (name) of the tag.
Value of the tag.
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.
