+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+# PSOpenAPITools - the PowerShell module for the Echo Server API
+
+Echo Server API
+
+This PowerShell module is automatically generated by the [OpenAPI Generator](https://openapi-generator.tech) project:
+
+- API version: 0.1.0
+- SDK version: 0.1.2
+- Build package: org.openapitools.codegen.languages.PowerShellClientCodegen
+
+<a id="frameworks-supported"></a>
+## Frameworks supported
+- PowerShell 6.2 or later
+
+<a id="dependencies"></a>
+## Dependencies
+
+<a id="installation"></a>
+## Installation
+
+
+To install from the source, run the following command to build and install the PowerShell module locally:
+```powershell
+Build.ps1
+Import-Module -Name '.\src\PSOpenAPITools' -Verbose
+```
+
+To avoid function name collision, one can use `-Prefix`, e.g. `Import-Module -Name '.\src\PSOpenAPITools' -Prefix prefix`
+
+To uninstall the module, simply run:
+```powershell
+Remove-Module -FullyQualifiedName @{ModuleName = "PSOpenAPITools"; ModuleVersion = "0.1.2"}
+```
+
+<a id="tests"></a>
+## Tests
+
+To install and run `Pester`, please execute the following commands in the terminal:
+
+```powershell
+Install-module -name Pester -force
+
+Invoke-Pester
+```
+
+For troubleshooting, please run `$DebugPreference = 'Continue'` to turn on debugging and disable it with `$DebugPreference = 'SilentlyContinue'` when done with the troubleshooting.

+.SYNOPSIS
+Sets the configuration for http signing.
+.DESCRIPTION
+
+Sets the configuration for the HTTP signature security scheme.
+The HTTP signature security scheme is used to sign HTTP requests with a key
+which is in possession of the API client.
+An 'Authorization' header is calculated by creating a hash of select headers,
+and optionally the body of the HTTP request, then signing the hash value using
+a key. The 'Authorization' header is added to outbound HTTP requests.
+
+Ref: https://openapi-generator.tech
+
+.PARAMETER KeyId
+KeyId for HTTP signing
+
+.PARAMETER KeyFilePath
+KeyFilePath for HTTP signing
+
+.PARAMETER KeyPassPhrase
+KeyPassPhrase, if the HTTP signing key is protected
+
+.PARAMETER HttpSigningHeader
+HttpSigningHeader list of HTTP headers used to calculate the signature. The two special signature headers '(request-target)' and '(created)'
+SHOULD be included.
+    The '(created)' header expresses when the signature was created.
+    The '(request-target)' header is a concatenation of the lowercased :method, an
+    ASCII space, and the :path pseudo-headers.
+If no headers are specified then '(created)' sets as default.
+
+.PARAMETER HashAlgorithm
+HashAlgorithm to calculate the hash, Supported values are "sha256" and "sha512"
+
+.PARAMETER SigningAlgorithm
+SigningAlgorithm specifies the signature algorithm, supported values are "RSASSA-PKCS1-v1_5" and "RSASSA-PSS"
+RSA key : Supported values "RSASSA-PKCS1-v1_5" and "RSASSA-PSS", for ECDSA key this parameter is not applicable
+
+.PARAMETER SignatureValidityPeriod
+SignatureValidityPeriod specifies the signature maximum validity time in seconds. It accepts integer value
