public interface AWSSecurityTokenServiceAsync extends AWSSecurityTokenService
The AWS Security Token Service (AWS STS) is a web service that enables you to request temporary, limited-privilege credentials for AWS Identity and Access Management (AWS IAM) users or for users that you authenticate (federated users). This guide provides descriptions of the AWS STS API. For more detailed information about using this service, go to Using Temporary Security Credentials .
NOTE: As an alternative to using the API, you can use one of the AWS SDKs, which consist of libraries and sample code for various programming languages and platforms (Java, Ruby, .NET, iOS, Android, etc.). The SDKs provide a convenient way to create programmatic access to AWS STS. For example, the SDKs take care of cryptographically signing requests, managing errors, and retrying requests automatically. For information about the AWS SDKs, including how to download and install them, see the Tools for Amazon Web Services page.
For information about setting up signatures and authorization through the API, go to Signing AWS API Requests in the AWS General Reference . For general information about the Query API, go to Making Query Requests in Using IAM . For information about using security tokens with other AWS products, go to Using Temporary Security Credentials to Access AWS in Using Temporary Security Credentials .
If you're new to AWS and need additional technical information about a specific AWS product, you can find the product's technical documentation at http://aws.amazon.com/documentation/ .
Endpoints
For information about AWS STS endpoints, see Regions and Endpoints in the AWS General Reference .
Recording API requests
AWS STS supports AWS CloudTrail, which is a service that records AWS calls for your AWS account and delivers log files to an Amazon S3 bucket. By using information collected by CloudTrail, you can determine what requests were successfully made to AWS STS, who made the request, when it was made, and so on. To learn more about CloudTrail, including how to turn it on and find your log files, see the AWS CloudTrail User Guide .

Returns a set of temporary credentials for an AWS account or IAM
user. The credentials consist of an access key ID, a secret access
key, and a security token. Typically, you use
GetSessionToken if you want use MFA to protect
programmatic calls to specific AWS APIs like Amazon EC2
StopInstances . MFA-enabled IAM users would need to call
GetSessionToken and submit an MFA code that is associated
with their MFA device. Using the temporary security credentials that
are returned from the call, IAM users can then make programmatic calls
to APIs that require MFA authentication.
The GetSessionToken action must be called by using the
long-term AWS security credentials of the AWS account or an IAM user.
Credentials that are created by IAM users are valid for the duration
that you specify, between 900 seconds (15 minutes) and 129600 seconds
(36 hours); credentials that are created by using account credentials
have a maximum duration of 3600 seconds (1 hour).
The permissions associated with the temporary security credentials
returned by GetSessionToken are based on the permissions
associated with account or IAM user whose credentials are used to call
the action. If GetSessionToken is called using root
account credentials, the temporary credentials have root account
permissions. Similarly, if GetSessionToken is called
using the credentials of an IAM user, the temporary credentials have
the same permissions as the IAM user.

create temporary credentials, go to
Creating Temporary Credentials to Enable Access for IAM Users

either a problem with the data in the request, or a server side issue.Future<DecodeAuthorizationMessageResult> decodeAuthorizationMessageAsync(DecodeAuthorizationMessageRequest decodeAuthorizationMessageRequest) throws AmazonServiceException, AmazonClientException
Decodes additional information about the authorization status of a request from an encoded message returned in response to an AWS request.
For example, if a user is not authorized to perform an action that he
or she has requested, the request returns a
Client.UnauthorizedOperation response (an HTTP 403
response). Some AWS actions additionally return an encoded message
that can provide details about this authorization failure.
NOTE: Only certain AWS actions return an encoded authorization message. The documentation for an individual action indicates whether that action returns an encoded message in addition to returning an HTTP code.
The message is encoded because the details of the authorization status
can constitute privileged information that the user who requested the
action should not see. To decode an authorization status message, a
user must be granted permissions via an AWS IAM policy to request the
DecodeAuthorizationMessage (
sts:DecodeAuthorizationMessage )
action.
The decoded message includes the following type of information:
decodeAuthorizationMessageRequest - Container for the necessary
parameters to execute the DecodeAuthorizationMessage operation on

Returns a set of temporary security credentials for users who have been authenticated via a SAML authentication response. This operation provides a mechanism for tying an enterprise identity store or directory to role-based AWS access without user-specific credentials or configuration.
The temporary security credentials returned by this operation consist
of an access key ID, a secret access key, and a security token.
Applications can use these temporary security credentials to sign
calls to AWS services. The credentials are valid for the duration that
you specified when calling AssumeRoleWithSAML , which can
be up to 3600 seconds (1 hour) or until the time specified in the SAML
authentication response's NotOnOrAfter value, whichever
is shorter.
NOTE:The maximum duration for a session is 1 hour, and the minimum duration is 15 minutes, even if values outside this range are specified.
Optionally, you can pass an AWS IAM access policy to this operation. The temporary security credentials that are returned by the operation have the permissions that are associated with the access policy of the role being assumed, except for any permissions explicitly denied by the policy you pass. This gives you a way to further restrict the permissions for the resulting temporary security credentials. These policies and any applicable resource-based policies are evaluated when calls to AWS are made using the temporary security credentials.
Before your application can call AssumeRoleWithSAML ,
you must configure your SAML identity provider (IdP) to issue the
claims required by AWS. Additionally, you must use AWS Identity and
Access Management (AWS IAM) to create a SAML provider entity in your
AWS account that represents your identity provider, and create an AWS
IAM role that specifies this SAML provider in its trust policy.
Calling AssumeRoleWithSAML does not require the use of
AWS security credentials. The identity of the caller is validated by
using keys in the metadata document that is uploaded for the SAML
provider entity for your identity provider.

Returns a set of temporary security credentials for users who have been authenticated in a mobile or web application with a web identity provider, such as Login with Amazon, Facebook, or Google.
Calling AssumeRoleWithWebIdentity does not require the
use of AWS security credentials. Therefore, you can distribute an
application (for example, on mobile devices) that requests temporary
security credentials without including long-term AWS credentials in
the application, and without deploying server-based proxy services
that use long-term AWS credentials. Instead, the identity of the
caller is validated by using a token from the web identity provider.
The temporary security credentials returned by this API consist of an
access key ID, a secret access key, and a security token. Applications
can use these temporary security credentials to sign calls to AWS
service APIs. The credentials are valid for the duration that you
specified when calling AssumeRoleWithWebIdentity , which
can be from 900 seconds (15 minutes) to 3600 seconds (1 hour). By
default, the temporary security credentials are valid for 1 hour.
Optionally, you can pass an AWS IAM access policy to this operation. The temporary security credentials that are returned by the operation have the permissions that are associated with the access policy of the role being assumed, except for any permissions explicitly denied by the policy you pass. This gives you a way to further restrict the permissions for the resulting temporary security credentials. These policies and any applicable resource-based policies are evaluated when calls to AWS are made using the temporary security credentials.
Before your application can call
AssumeRoleWithWebIdentity , you must have an identity
token from a supported identity provider and create a role that the
application can assume. The role that your application assumes must
trust the identity provider that is associated with the identity
token. In other words, the identity provider must be specified in the
role's trust policy.

Returns a set of temporary security credentials (consisting of an
access key ID, a secret access key, and a security token) for a
federated user. A typical use is in a proxy application that is
getting temporary security credentials on behalf of distributed
applications inside a corporate network. Because you must call the
GetFederationToken action using the long-term security
credentials of an IAM user, this call is appropriate in contexts where
those credentials can be safely stored, usually in a server-based
application.
Note: Do not use this call in mobile applications or
client-based web applications that directly get temporary security
credentials. For those types of applications, use
AssumeRoleWithWebIdentity .
The GetFederationToken action must be called by using the
long-term AWS security credentials of the AWS account or an IAM user.
Credentials that are created by IAM users are valid for the specified
duration, between 900 seconds (15 minutes) and 129600 seconds (36

a maximum duration of 3600 seconds (1 hour).
Optionally, you can pass an AWS IAM access policy to this operation.
The temporary security credentials that are returned by the operation
have the permissions that are associated with the entity that is

Returns a set of temporary security credentials (consisting of an
access key ID, a secret access key, and a security token) that you can
use to access AWS resources that you might not normally have access
to. Typically, you use AssumeRole for cross-account
access or federation.
Important: You cannot call AssumeRole by using
AWS account credentials; access will be denied. You must use IAM user
credentials or temporary security credentials to call
AssumeRole .
For cross-account access, imagine that you own multiple accounts and need to access resources in each account. You could create long-term credentials in each account to access those resources. However, managing all those credentials and remembering which one can access which account can be time consuming. Instead, you can create one set of long-term credentials in one account and then use temporary security credentials to access all the other accounts by assuming roles in those accounts. For more information about roles, see Roles in Using IAM .
For federation, you can, for example, grant single sign-on access to
the AWS Management Console. If you already have an identity and
authentication system in your corporate network, you don't have to
recreate user identities in AWS in order to grant those user
identities access to AWS. Instead, after a user has been
authenticated, you call AssumeRole (and specify the role
with the appropriate permissions) to get temporary security
credentials for that user. With those temporary security credentials,
you construct a sign-in URL that users can use to access the console.
For more information, see
Scenarios for Granting Temporary Access
in AWS Security Token Service .
The temporary security credentials are valid for the duration that
you specified when calling AssumeRole , which can be from
900 seconds (15 minutes) to 3600 seconds (1 hour). The default is 1
hour.
Optionally, you can pass an AWS IAM access policy to this operation. The temporary security credentials that are returned by the operation have the permissions that are associated with the access policy of the role that is being assumed, except for any permissions explicitly denied by the policy you pass. This gives you a way to further restrict the permissions for the resulting temporary security credentials. These policies and any applicable resource-based policies are evaluated when calls to AWS are made using the temporary security credentials.
To assume a role, your AWS account must be trusted by the role. The
trust relationship is defined in the role's trust policy when the IAM
role is created. You must also have a policy that allows you to call
sts:AssumeRole .
Using MFA with AssumeRole
You can optionally include multi-factor authentication (MFA)
information when you call AssumeRole . This is useful for
cross-account scenarios in which you want to make sure that the user
who is assuming the role has been authenticated using an AWS MFA
device. In that scenario, the trust policy of the role being assumed
includes a condition that tests for MFA authentication; if the caller
does not include valid MFA information, the request to assume the role
is denied. The condition in a a trust policy that tests for MFA
authentication might look like the following example.
"Condition": {"Null": {"aws:MultiFactorAuthAge": false}}
For more information, see Configuring MFA-Protected API Access in the Using AWS IAM guide.
To use MFA with AssumeRole , you pass values for the
SerialNumber and TokenCode parameters. The
SerialNumber value identifies the user's hardware or
virtual MFA device. The TokenCode is the temporary
one-time password (TOTP) that the MFA devices produces.

with the appropriate permissions) to get temporary security
credentials for that user. With those temporary security credentials,
you construct a sign-in URL that users can use to access the console.
For more information, see
Scenarios for Granting Temporary Access
in AWS Security Token Service .
The temporary security credentials are valid for the duration that
you specified when calling AssumeRole , which can be from
900 seconds (15 minutes) to 3600 seconds (1 hour). The default is 1
hour.
Optionally, you can pass an AWS IAM access policy to this operation. The temporary security credentials that are returned by the operation have the permissions that are associated with the access policy of the role that is being assumed, except for any permissions explicitly denied by the policy you pass. This gives you a way to further restrict the permissions for the resulting temporary security credentials. These policies and any applicable resource-based policies are evaluated when calls to AWS are made using the temporary security credentials.
To assume a role, your AWS account must be trusted by the role. The
trust relationship is defined in the role's trust policy when the IAM
role is created. You must also have a policy that allows you to call
sts:AssumeRole .
Using MFA with AssumeRole
You can optionally include multi-factor authentication (MFA)
information when you call AssumeRole . This is useful for
cross-account scenarios in which you want to make sure that the user
who is assuming the role has been authenticated using an AWS MFA
device. In that scenario, the trust policy of the role being assumed
includes a condition that tests for MFA authentication; if the caller
does not include valid MFA information, the request to assume the role
is denied. The condition in a a trust policy that tests for MFA
authentication might look like the following example.
"Condition": {"Null": {"aws:MultiFactorAuthAge": false}}
For more information, see Configuring MFA-Protected API Access in the Using AWS IAM guide.
To use MFA with AssumeRole , you pass values for the
SerialNumber and TokenCode parameters. The
SerialNumber value identifies the user's hardware or
virtual MFA device. The TokenCode is the temporary
one-time password (TOTP) that the MFA devices produces.
assumeRoleRequest - Container for the necessary parameters to
execute the AssumeRole operation on AWSSecurityTokenService.asyncHandler - Asynchronous callback handler for events in the
life-cycle of the request. Users could provide the implementation of
the four callback methods in this interface to process the operation
result or handle the exception.AmazonClientException - If any internal errors are encountered inside the client while
attempting to make the request or handle the response. For example
if a network connection is not available.AmazonServiceException - If an error response is returned by AWSSecurityTokenService indicating
either a problem with the data in the request, or a server side issue.Copyright © 2016. All rights reserved.
