# RevokeCertificate


Revokes a certificate that was issued inside AWS Private CA. If you enable a certificate revocation list (CRL) when you create or update your private CA, information about the revoked certificates will be included in the CRL. AWS Private CA writes the CRL to an S3 bucket that you specify. A CRL is typically updated approximately 30 minutes after a certificate is revoked. If for any reason the CRL update fails, AWS Private CA attempts makes further attempts every 15 minutes. With Amazon CloudWatch, you can create alarms for the metrics `CRLGenerated` and `MisconfiguredCRLBucket`. For more information, see [Supported CloudWatch Metrics](https://docs.aws.amazon.com/privateca/latest/userguide/PcaCloudWatch.html).

**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](https://docs.aws.amazon.com/privateca/latest/userguide/crl-planning.html#s3-policies).

 AWS Private CA also writes revocation information to the audit report. For more information, see [CreateCertificateAuthorityAuditReport](https://docs.aws.amazon.com/privateca/latest/APIReference/API_CreateCertificateAuthorityAuditReport.html).

**Note**  
You cannot revoke a root CA self-signed certificate.

## Request Syntax


```
{
   "CertificateAuthorityArn": "string",
   "CertificateSerial": "string",
   "RevocationReason": "string"
}
```

## Request Parameters


For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

The request accepts the following data in JSON format.

 ** [CertificateAuthorityArn](#API_RevokeCertificate_RequestSyntax) **   <a name="privateca-RevokeCertificate-request-CertificateAuthorityArn"></a>
Amazon Resource Name (ARN) of the private CA that issued the certificate to be revoked. This must be 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+=,.@-]+)*`   
Required: Yes

 ** [CertificateSerial](#API_RevokeCertificate_RequestSyntax) **   <a name="privateca-RevokeCertificate-request-CertificateSerial"></a>
Serial number of the certificate to be revoked. This must be in hexadecimal format. You can retrieve the serial number by calling [GetCertificate](https://docs.aws.amazon.com/privateca/latest/APIReference/API_GetCertificate.html) with the Amazon Resource Name (ARN) of the certificate you want and the ARN of your private CA. The **GetCertificate** action retrieves the certificate in the PEM format. You can use the following OpenSSL command to list the certificate in text format and copy the hexadecimal serial number.   
 `openssl x509 -in file_path -text -noout`   
You can also copy the serial number from the console or use the [DescribeCertificate](https://docs.aws.amazon.com/acm/latest/APIReference/API_DescribeCertificate.html) action in the * AWS Certificate Manager API Reference*.   
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 128.  
Required: Yes

 ** [RevocationReason](#API_RevokeCertificate_RequestSyntax) **   <a name="privateca-RevokeCertificate-request-RevocationReason"></a>
Specifies why you revoked the certificate.  
Type: String  
Valid Values: `UNSPECIFIED | KEY_COMPROMISE | CERTIFICATE_AUTHORITY_COMPROMISE | AFFILIATION_CHANGED | SUPERSEDED | CESSATION_OF_OPERATION | PRIVILEGE_WITHDRAWN | A_A_COMPROMISE`   
Required: Yes

## Response Elements
