This assumes you are familiar with the basic usage of the Gateway Migration Utility. Create an XML file.

touch stored_password.xml

Add the following to the XML file. In this example, stored password foo with a value of bar will be created.

<l7:StoredPassword xmlns:l7="http://ns.l7tech.com/2010/04/gateway-management">
  <l7:Name>foo</l7:Name>
  <l7:Password>bar</l7:Password>
  <l7:Properties>
      <l7:Property key="description">
          <l7:StringValue>foo password</l7:StringValue>
      </l7:Property>
      <l7:Property key="type">
          <l7:StringValue>Password</l7:StringValue>
      </l7:Property>
      <l7:Property key="usageFromVariable">
          <l7:BooleanValue>true</l7:BooleanValue>
      </l7:Property>
  </l7:Properties>
</l7:StoredPassword>

Issue the following command to create the stored password.

/path/to/GatewayMigrationUtility.sh restman
-host apig.example.com
-port 8443
-username john.doe
-password f5VPX0yUJPg.m4BrjdgMv84UgktddJD3xA
-method POST
-path '1.0/passwords'
-request stored_password.xml

Or the -argFile option can be used, to reduce the number of options that are used on the command line.

/path/to/GatewayMigrationUtility.sh restman
-argFile example.properties
-method POST
-path '1.0/passwords'
-request stored_password.xml

Something like this should be displayed.

Status: 201 Created

You can then use the Gateway Migration Utility to ensure the stored password was created.

/path/to/GatewayMigrationUtility.sh restman
-argFile example.properties
-method GET
-path '1.0/passwords'
-query 'name=foo'

Which should return something like this.
