/**
* Client for accessing AWS STS. All service calls made using this client are
* blocking, and will not return until the service call completes.
*
* AWS Security Token Service
*
* The AWS Security Token Service (STS) is a web service that enables you to
* request temporary, limited-privilege credentials for AWS Identity and Access
* Management (IAM) users or for users that you authenticate (federated users).
* This guide provides descriptions of the STS API. For more detailed
* information about using this service, go to Temporary Security Credentials.
*
*
*
* 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 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 AWS Services That Work with IAM in the IAM User Guide.
*
*
* 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
*
*
* The AWS Security Token Service (STS) has a default endpoint of
* https://sts.amazonaws.com that maps to the US East (N. Virginia) region.
* Additional regions are available and are activated by default. For more
* information, see Activating and Deactivating AWS STS in an AWS Region in the IAM User
* Guide.
*
*
* For information about STS endpoints, see Regions and Endpoints in the AWS General Reference.
*
*
* Recording API requests
*
*
* 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 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 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. For a comparison of AssumeRole with the other
* APIs that produce temporary credentials, see Requesting Temporary Security Credentials and Comparing the AWS STS APIs in the IAM User Guide.
*
*
* Important: You cannot call AssumeRole by using AWS
* root account credentials; access is denied. You must use credentials for
* an IAM user or an IAM role 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 IAM
* Roles (Delegation and Federation) in the IAM User Guide.
*
*
* 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 Common Scenarios for Temporary Credentials in the IAM User
* Guide.
*
*
* The temporary security credentials are valid for the duration that you
* specified when calling AssumeRole, which can be from 900
* seconds (15 minutes) to a maximum of 3600 seconds (1 hour). The default
* is 1 hour.
*
*
* The temporary security credentials created by AssumeRole can
* be used to make API calls to any AWS service with the following
* exception: you cannot call the STS service's
* GetFederationToken or GetSessionToken APIs.
*
*
* Optionally, you can pass an IAM access policy to this operation. If you
* choose not to pass a policy, the temporary security credentials that are
* returned by the operation have the permissions that are defined in the
* access policy of the role that is being assumed. If you pass a policy to
* this operation, the temporary security credentials that are returned by
* the operation have the permissions that are allowed by both the access
* policy of the role that is being assumed, and the policy
* that you pass. This gives you a way to further restrict the permissions
* for the resulting temporary security credentials. You cannot use the
* passed policy to grant permissions that are in excess of those allowed by
* the access policy of the role that is being assumed. For more
* information, see Permissions for AssumeRole, AssumeRoleWithSAML, and
* AssumeRoleWithWebIdentity in the IAM User Guide.
*
*
* 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 role is
* created. That trust policy states which accounts are allowed to delegate
* access to this account's role.
*
*
* The user who wants to access the role must also have permissions
* delegated from the role's administrator. If the user is in a different
* account than the role, then the user's administrator must attach a policy
* that allows the user to call AssumeRole on the ARN of the role in the
* other account. If the user is in the same account as the role, then you
* can either attach a policy to the user (identical to the previous
* different account user), or you can add the user as a principal directly
* in the role's trust policy
*
*
* 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 trust policy that tests for MFA authentication might look like the
* following example.
*
*
* "Condition": {"Bool": {"aws:MultiFactorAuthPresent": true}}
*
*
* For more information, see Configuring MFA-Protected API Access in the IAM User Guide
* 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 time-based one-time
* password (TOTP) that the MFA devices produces.
*
*
* @param assumeRoleRequest
* @return Result of the AssumeRole operation returned by the service.
* @throws MalformedPolicyDocumentException
* The request was rejected because the policy document was
* malformed. The error message describes the specific error.
* @throws PackedPolicyTooLargeException
* The request was rejected because the policy document was too
* large. The error message describes how big the policy document
* is, in packed form, as a percentage of what the API allows.
* @throws RegionDisabledException
* STS is not activated in the requested region for the account that
* is being asked to generate credentials. The account administrator
* must use the IAM console to activate STS in that region. For more
* information, see Activating and Deactivating AWS STS in an AWS Region in the
* IAM User Guide.

*
*
* 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

* that represents your identity provider, and create an IAM role that
* specifies this SAML provider in its trust policy.
*
*
* Calling AssumeRoleWithSAML does not require the use of AWS

* keys in the metadata document that is uploaded for the SAML provider
* entity for your identity provider.
*
*
*
* Calling AssumeRoleWithSAML can result in an entry in your
* AWS CloudTrail logs. The entry includes the value in the
* NameID element of the SAML assertion. We recommend that you
* use a NameIDType that is not associated with any personally identifiable

*
*
*
* For mobile applications, we recommend that you use Amazon Cognito. You

*
*
* To learn more about Amazon Cognito, see Amazon Cognito Overview in the AWS SDK for Android Developer
* Guide guide and Amazon Cognito Overview in the AWS SDK for iOS Developer

*
*
*
* Calling AssumeRoleWithWebIdentity does not require the use

* (for example, on mobile devices) that requests temporary security

*
*
* Before your application can call AssumeRoleWithWebIdentity,

* with the identity token. In other words, the identity provider must be
* specified in the role's trust policy.
*
*
*
* Calling AssumeRoleWithWebIdentity can result in an entry in
* your AWS CloudTrail logs. The entry includes the Subject of the provided Web Identity Token. We recommend that you

* 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.
*
*
*
* 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 IAM policy to request the
* DecodeAuthorizationMessage (
* sts:DecodeAuthorizationMessage) action.
*
*
* The decoded message includes the following type of information:
*
*
* -
*
* Whether the request was denied due to an explicit deny or due to the
* absence of an explicit allow. For more information, see Determining Whether a Request is Allowed or Denied in the IAM
* User Guide.
*
*
* -
*
* The principal who made the request.
*
*
* -

/**
*
* 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 gets 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. For a comparison of
* GetFederationToken with the other APIs that produce
* temporary credentials, see Requesting Temporary Security Credentials and Comparing the AWS STS APIs in the IAM User Guide.
*
*
*
* If you are creating a mobile-based or browser-based app that can
* authenticate users using a web identity provider like Login with Amazon,
* Facebook, Google, or an OpenID Connect-compatible identity provider, we
* recommend that you use Amazon
* Cognito or AssumeRoleWithWebIdentity. For more
* information, see Federation Through a Web-based Identity Provider.
*
*
*
* The GetFederationToken action must be called by using the
* long-term AWS security credentials of an IAM user. You can also call
* GetFederationToken using the security credentials of an AWS
* root account, but we do not recommended it. Instead, we recommend that
* you create an IAM user for the purpose of the proxy application and then
* attach a policy to the IAM user that limits federated users to only the
* actions and resources that they need access to. For more information, see
* IAM
* Best Practices in the IAM User Guide.
*
*
* The temporary security credentials that are obtained by using the
* long-term credentials of an IAM user are valid for the specified
* duration, from 900 seconds (15 minutes) up to a maximium of 129600
* seconds (36 hours). The default is 43200 seconds (12 hours). Temporary
* credentials that are obtained by using AWS root account credentials have
* a maximum duration of 3600 seconds (1 hour).
*
*
* The temporary security credentials created by
* GetFederationToken can be used to make API calls to any AWS
* service with the following exceptions:
*
*
* -
*
* You cannot use these credentials to call any IAM APIs.
*
*
* -
*
* You cannot call any STS APIs.
*
*
*
*
* Permissions
*
*
* The permissions for the temporary security credentials returned by
* GetFederationToken are determined by a combination of the
* following:
*
*
* -
*
* The policy or policies that are attached to the IAM user whose
* credentials are used to call GetFederationToken.
*
*
* -
*
* The policy that is passed as a parameter in the call.
*
*
*
*
* The passed policy is attached to the temporary security credentials that
* result from the GetFederationToken API call--that is, to the
* federated user. When the federated user makes an AWS request, AWS
* evaluates the policy attached to the federated user in combination with
* the policy or policies attached to the IAM user whose credentials were
* used to call GetFederationToken. AWS allows the federated
* user's request only when both the federated user and the
* IAM user are explicitly allowed to perform the requested action. The
* passed policy cannot grant more permissions than those that are defined
* in the IAM user policy.
*
*
* A typical use case is that the permissions of the IAM user whose
* credentials are used to call GetFederationToken are designed
* to allow access to all the actions and resources that any federated user
* will need. Then, for individual users, you pass a policy to the operation
* that scopes down the permissions to a level that's appropriate to that
* individual user, using a policy that allows only a subset of permissions
* that are granted to the IAM user.
*
*
* If you do not pass a policy, the resulting temporary security credentials
* have no effective permissions. The only exception is when the temporary
* security credentials are used to access a resource that has a
* resource-based policy that specifically allows the federated user to
* access the resource.
*
*
* For more information about how permissions work, see Permissions for GetFederationToken. For information about using
* GetFederationToken to create temporary security credentials,
* see GetFederationToken—Federation Through a Custom Identity Broker.
*
*
* @param getFederationTokenRequest
* @return Result of the GetFederationToken operation returned by the
* service.
* @throws MalformedPolicyDocumentException
* The request was rejected because the policy document was
* malformed. The error message describes the specific error.
* @throws PackedPolicyTooLargeException
* The request was rejected because the policy document was too
* large. The error message describes how big the policy document
* is, in packed form, as a percentage of what the API allows.
* @throws RegionDisabledException
* STS is not activated in the requested region for the account that
* is being asked to generate credentials. The account administrator
* must use the IAM console to activate STS in that region. For more
* information, see Activating and Deactivating AWS STS in an AWS Region in the

/**
*
* 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 to 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. If you do not
* supply a correct MFA code, then the API returns an access denied error.
* For a comparison of GetSessionToken with the other APIs that
* produce temporary credentials, see Requesting Temporary Security Credentials and Comparing the AWS STS APIs in the IAM User Guide.
*
*
* 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, from 900 seconds (15 minutes) up to a maximum of 129600
* seconds (36 hours), with a default of 43200 seconds (12 hours);
* credentials that are created by using account credentials can range from
* 900 seconds (15 minutes) up to a maximum of 3600 seconds (1 hour), with a
* default of 1 hour.
*
*
* The temporary security credentials created by
* GetSessionToken can be used to make API calls to any AWS
* service with the following exceptions:
*
*
* -
*
* You cannot call any IAM APIs unless MFA authentication information is
* included in the request.
*
*
* -
*
* You cannot call any STS API except AssumeRole.
*
*
*
*
*
* We recommend that you do not call GetSessionToken with root
* account credentials. Instead, follow our best practices by creating one or more IAM users, giving them the
* necessary permissions, and using IAM users for everyday interaction with
* AWS.
*
*
*
* 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.
