You can use the ACM PCA API to create a private certificate authority (CA). You must first call the CreateCertificateAuthority operation. If successful, the operation returns an Amazon Resource Name (ARN) for your private CA. Use this ARN as input to the GetCertificateAuthorityCsr operation to retrieve the certificate signing request (CSR) for your private CA certificate. Sign the CSR using the root or an intermediate CA in your on-premises PKI hierarchy, and call the ImportCertificateAuthorityCertificate to import your signed private CA certificate into ACM PCA.
Use your private CA to issue and revoke certificates. These are private certificates that identify and secure client computers, servers, applications, services, devices, and users over SSLS/TLS connections within your organization. Call the IssueCertificate operation to issue a certificate. Call the RevokeCertificate operation to revoke a certificate.
Certificates issued by your private CA can be trusted only within your organization, not publicly.
Your private CA can optionally create a certificate revocation list (CRL) to track the certificates you revoke. To create a CRL, you must specify a RevocationConfiguration object when you call the CreateCertificateAuthority operation. ACM PCA writes the CRL to an S3 bucket that you specify. You must specify a bucket policy that grants ACM PCA write permission.
You can also call the CreateCertificateAuthorityAuditReport to create an optional audit report, which enumerates all of the issued, valid, expired, and revoked certificates from the CA.
Each ACM PCA API operation has a throttling limit which determines the number of times the operation can be called per second. For more information, see API Rate Limits in ACM PCA in the ACM PCA user guide.
Contains information about the certificate subject. The certificate can be one issued by your private certificate authority (CA) or it can be your private CA certificate. The Subject field in the certificate identifies the entity that owns or controls the public key in the certificate. The entity can be a user, computer, device, or service. The Subject must contain an X.500 distinguished name (DN). A DN is a sequence of relative distinguished names (RDNs). The RDNs are separated by commas in the certificate. The DN must be unique for each entity, but your private CA can issue more than one certificate with the same DN to the same entity.
A client for the ACM-PCA API.
Contains information about your private certificate authority (CA). Your private CA can issue and revoke X.509 digital certificates. Digital certificates verify that the entity named in the certificate Subject field owns or controls the public key contained in the Subject Public Key Info field. Call the CreateCertificateAuthority operation to create your private CA. You must then call the GetCertificateAuthorityCertificate operation to retrieve a private CA certificate signing request (CSR). Take the CSR to your on-premises CA and sign it with the root CA certificate or a subordinate certificate. Call the ImportCertificateAuthorityCertificate operation to import the signed certificate into AWS Certificate Manager (ACM).
Contains configuration information for your private certificate authority (CA). This includes information about the class of public key algorithm and the key pair that your private CA creates when it issues a certificate, the signature algorithm it uses used when issuing certificates, and its X.500 distinguished name. You must specify this information when you call the CreateCertificateAuthority operation.
Contains configuration information for a certificate revocation list (CRL). Your private certificate authority (CA) creates base CRLs. Delta CRLs are not supported. You can enable CRLs for your new or an existing private CA by setting the Enabled parameter to
Your private CA uses the value in the ExpirationInDays parameter to calculate the nextUpdate field in the CRL. The CRL is refreshed at 1/2 the age of next update or when a certificate is revoked. When a certificate is revoked, it is recorded in the next CRL that is generated and in the next audit report. Only time valid certificates are listed in the CRL. Expired certificates are not included.
CRLs contain the following fields:
Certificate revocation lists created by ACM PCA are DER-encoded. You can use the following OpenSSL command to list a CRL.
Certificate revocation information used by the CreateCertificateAuthority and UpdateCertificateAuthority operations. Your private certificate authority (CA) can create and maintain a certificate revocation list (CRL). A CRL contains information about certificates revoked by your CA. For more information, see RevokeCertificate.
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 operation. To remove a tag, call the UntagCertificateAuthority operation.
Length of time for which the certificate issued by your private certificate authority (CA), or by the private CA itself, is valid in days, months, or years. You can issue a certificate by calling the IssueCertificate operation.
