The following options can be provided within a hash to the `presignRequest` method:\n\n- `request` - The request to be signed. This parameter will not be\n modified during the signing process but will instead be cloned.\n The shape of the request should be an object with the following defined:\n - `method` - HTTP method (e.g. 'GET', 'PUT', etc).\n - `headers` - A mapping of header names to string values.\n Multiple values for the same header should be represented as a single\n string with values separated by `,`.\n Keys should be considered case insensitive.\n - `body` - Optional. May be a string, ArrayBuffer, or stream.\n- `signingDate` - Optional. The date and time to be used as signature metadata.\n This value should be a Date object, a unix (epoch) timestamp, or\n a string that can be unerstood by the JavaScript `Date` constructor.\n Defaults to `new Date()`.\n- `expiration` - The time at which the signed URL should no longer\n be honored.\n This value should be a Date object, a unix (epoch) timestamp, or a\n string that can be understood by the JavaScript `Date` constructor.\n- `hoistHeaders` - Optional.

May be a string, ArrayBuffer, or stream.\n- `signingDate` - Optional. The date and time to be used as signature metadata.\n This value should be a Date object, a unix (epoch) timestamp, or\n a string that can be unerstood by the JavaScript `Date` constructor.\n Defaults to `new Date()`.\n- `unsignableHeaders` - Optional.

The date and time to be used as signature metadata.\n This value should be a Date object, a unix (epoch) timestamp, or\n a string that can be unerstood by the JavaScript `Date` constructor.\n Defaults to `new Date()`.\n - `unsignableHeaders` - Optional. An object whose keys represents\n headers that cannot be signed. All headers in the provided request\n will have their names converted to lower case and then checked for\n existence in the `unsignableHeaders` object using the `in` operator.\n Defaults to an object whose keys are lower-cased transfer-specific\n headers (such as `user-agent`, `referer`, `expect`, etc).\n\n### sign\n\nThe `sign` method accepts a request or string and returns a Promise that\nresolves with a signed request or signed string.\n\nThe signed request will have an expiration and can be passed directly\nto an HTTP client.\n\nThe following options can be provided within a hash to the `sign` method:\n\n- `request` or `string`:\n - `request` - The request to be signed. This parameter will not be\n modified during the signing process but will instead be cloned.\n The shape of the request should be an object with the following defined:\n - `method` - HTTP method (e.g. 'GET', 'PUT', etc).\n - `headers` - A mapping of header names to string values.\n Multiple values for the same header should be represented as a single\n string with values separated by `,`.\n Keys should be considered case insensitive.\n - `body` - Optional. May be a string, ArrayBuffer, or stream.\n - or `string`\n- `options` object\n - `signingDate` - Optional.
