# AWS::ACMPCA Construct Library This module is part of the [AWS Cloud Development Kit](https://github.com/aws/aws-cdk) project. ```ts nofixture import * as acmpca from 'aws-cdk-lib/aws-acmpca'; ``` ## Certificate Authority This package contains a `CertificateAuthority` class. At the moment, you cannot create new Authorities using it, but you can import existing ones using the `fromCertificateAuthorityArn` static method: ```ts const certificateAuthority = acmpca.CertificateAuthority.fromCertificateAuthorityArn(this, 'CA', 'arn:aws:acm-pca:us-east-1:123456789012:certificate-authority/023077d8-2bfa-4eb0-8f22-05c96deade77'); ``` ## Low-level `Cfn*` classes You can always use the low-level classes (starting with `Cfn*`) to create resources like the Certificate Authority: ```ts const cfnCertificateAuthority = new acmpca.CfnCertificateAuthority(this, 'CA', { type: 'ROOT', keyAlgorithm: 'RSA_2048', signingAlgorithm: 'SHA256WITHRSA', subject: { country: 'US', organization: 'string', organizationalUnit: 'string', distinguishedNameQualifier: 'string', state: 'string', commonName: '123', serialNumber: 'string', locality: 'string', title: 'string', surname: 'string', givenName: 'string', initials: 'DG', pseudonym: 'string', generationQualifier: 'DBG', }, }); ``` If you need to pass the higher-level `ICertificateAuthority` somewhere, you can get it from the lower-level `CfnCertificateAuthority` using the same `fromCertificateAuthorityArn` method: ```ts declare const cfnCertificateAuthority: acmpca.CfnCertificateAuthority; const certificateAuthority = acmpca.CertificateAuthority.fromCertificateAuthorityArn(this, 'CertificateAuthority', cfnCertificateAuthority.attrArn); ```
