[ aws . acm ]



Imports a certificate into Certificate Manager (ACM) to use with services that are integrated with ACM. Note that integrated services allow only certificate types and keys they support to be associated with their resources. Further, their support differs depending on whether the certificate is imported into IAM or into ACM. For more information, see the documentation for each service. For more information about importing certificates into ACM, see Importing Certificates in the Certificate Manager User Guide .


ACM does not provide managed renewal for certificates that you import.

Note the following guidelines when importing third party certificates:

  • You must enter the private key that matches the certificate you are importing.
  • The private key must be unencrypted. You cannot import a private key that is protected by a password or a passphrase.
  • The private key must be no larger than 5 KB (5,120 bytes).
  • If the certificate you are importing is not self-signed, you must enter its certificate chain.
  • If a certificate chain is included, the issuer must be the subject of one of the certificates in the chain.
  • The certificate, private key, and certificate chain must be PEM-encoded.
  • The current time must be between the Not Before and Not After certificate fields.
  • The Issuer field must not be empty.
  • The OCSP authority URL, if present, must not exceed 1000 characters.
  • To import a new certificate, omit the CertificateArn argument. Include this argument only when you want to replace a previously imported certificate.
  • When you import a certificate by using the CLI, you must specify the certificate, the certificate chain, and the private key by their file names preceded by fileb:// . For example, you can specify a certificate saved in the C:\temp folder as fileb://C:\temp\certificate_to_import.pem . If you are making an HTTP or HTTPS Query request, include these arguments as BLOBs.
  • When you import a certificate by using an SDK, you must specify the certificate, the certificate chain, and the private key files in the manner required by the programming language you’re using.
  • The cryptographic algorithm of an imported certificate must match the algorithm of the signing CA. For example, if the signing CA key type is RSA, then the certificate key type must also be RSA.

This operation returns the Amazon Resource Name (ARN) of the imported certificate.

--certificate-arn (string)

The Amazon Resource Name (ARN) of an imported certificate to replace. To import a new certificate, omit this field.

--certificate (blob)

The certificate to import.

--private-key (blob)

The private key that matches the public key in the certificate.

--certificate-chain (blob)

The PEM encoded certificate chain.

--tags (list)

One or more resource tags to associate with the imported certificate.

Note: You cannot apply tags when reimporting a certificate.


A key-value pair that identifies or specifies metadata about an ACM resource.

Key -> (string)

The key of the tag.

Value -> (string)

The value of the tag.

Shorthand Syntax:

Key=string,Value=string ...

JSON Syntax:

    "Key": "string",
    "Value": "string"

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table
  • yaml
  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.



To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To import a certificate into ACM.

The following import-certificate command imports a certificate into ACM. Replace the file names with your own:

aws acm import-certificate --certificate file://Certificate.pem --certificate-chain file://CertificateChain.pem --private-key file://PrivateKey.pem


CertificateArn -> (string)

The Amazon Resource Name (ARN) of the imported certificate.
