Lists information about your private certificate authority (CA) or one that has been shared with you. You specify the private CA on input by its ARN (Amazon Resource Name). The output contains the status of your CA. This can be any of the following:
CREATING - Amazon Web Services Private CA is creating your private certificate authority.PENDING_CERTIFICATE - The certificate is pending. You must use your Amazon Web Services Private CA-hosted or on-premises root or subordinate CA to sign your private CA CSR and then import it into Amazon Web Services Private CA.ACTIVE - Your private CA is active.DISABLED - Your private CA has been disabled.EXPIRED - Your private CA certificate has expired.FAILED - Your private CA has failed. Your CA can fail because of problems such a network outage or back-end Amazon Web Services failure or other errors. A failed CA can never return to the pending state. You must create a new CA.DELETED - Your private CA is within the restoration period, after which it is permanently deleted. The length of time remaining in the CA's restoration period is also included in this action's output.See also: AWS API Documentation

Information about the Online Certificate Status Protocol (OCSP) configuration or certificate revocation list (CRL) created and maintained by your private CA.
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 .
The period during which a deleted CA can be restored. For more information, see the PermanentDeletionTimeInDays parameter of the DeleteCertificateAuthorityRequest action.
Defines a cryptographic key management compliance standard used for handling CA keys.
Default: FIPS_140_2_LEVEL_3_OR_HIGHER
Note: Amazon Web Services Region ap-northeast-3 supports only FIPS_140_2_LEVEL_2_OR_HIGHER. You must explicitly specify this parameter and value when creating a CA in that Region. Specifying a different value (or no value) results in an InvalidArgsException with the message "A certificate authority cannot be created in this region with the specified security standard."
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.
