# DeleteCertificateAuthority
<a name="JavaApi-DeleteCertificateAuthority"></a>

The following Java sample shows how to use the [DeleteCertificateAuthority](https://docs.aws.amazon.com/privateca/latest/APIReference/API_DeleteCertificateAuthority.html) operation.

This operation deletes the private certificate authority (CA) that you created using the [CreateCertificateAuthority](https://docs.aws.amazon.com/privateca/latest/APIReference/API_CreateCertificateAuthority.html) operation. The `DeleteCertificateAuthority` operation requires that you provide an ARN for the CA to be deleted. You can find the ARN by calling the [ListCertificateAuthorities](https://docs.aws.amazon.com/privateca/latest/APIReference/API_ListCertificateAuthorities.html) operation. You can delete the private CA immediately if its status is `CREATING` or `PENDING_CERTIFICATE`. If you have already imported the certificate, however, you cannot delete it immediately. You must first disable the CA by calling the [UpdateCertificateAuthority](https://docs.aws.amazon.com/privateca/latest/APIReference/API_UpdateCertificateAuthority.html) operation and set the `Status` parameter to `DISABLED`. You can then use the `PermanentDeletionTimeInDays` parameter in the `DeleteCertificateAuthority` operation to specify the number of days, from 7 to 30. During that period the private CA can be restored to `disabled` status. By default, if you do not set the `PermanentDeletionTimeInDays` parameter, the restoration period is 30 days. After this period expires, the private CA is permanently deleted and cannot be restored. For more information, see [Restore a CA](PCARestoreCA.md). 

For a Java example that shows you how to use the [RestoreCertificateAuthority](https://docs.aws.amazon.com/privateca/latest/APIReference/API_RestoreCertificateAuthority.html) operation, see [RestoreCertificateAuthority](JavaApi-RestoreCertificateAuthority.md).
