Call SSPI Failed Error with MySQL.NET Connector in PowerShell

Title: Resolving Issues with MySQL.NET Connector PowerShell Querying Database Using Connector Version 9.1 and 8.0.33 (Insecure Ciphers Disabled)

Introduction: In this article, we will discuss how to resolve issues when using MySQL.NET Connector PowerShell to query a database with connector versions 9.1 and 8.0.33, while ensuring insecure ciphers are disabled.

Prerequisites:

• MySQL Server installed and running
• MySQL.NET Connector installed (Version 9.1 or 8.0.33)
• PowerShell installed

Steps to resolve the issue:

1. Disable insecure ciphers on the MySQL Server:

   SET GLOBAL ssl_cipher = 'ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-RC4-SHA:AES256-SHA256:AES128-SHA256:RC4-SHA';
   

   Note: The above command sets the cipher list to use secure ciphers. You can modify the list according to your requirements.

2. Install the MySQL.Data NuGet package in your PowerShell script or project:

   Install-Package MySql.Data
   

3. Update your PowerShell script to use the MySQL.Data assembly:

   Add-Type -AssemblyName MySql.Data
   
   $connectionString = "server=localhost;user=yourUsername;password=yourPassword;database=yourDatabase;SslMode=None;"
   
   $connection = New-Object MySql.Data.MySqlClient.MySqlConnection($connectionString)
   
   $connection.Open()
   
   $command = New-Object MySql.Data.MySqlClient.MySqlCommand("SELECT * FROM yourTable", $connection)
   
   $reader = $command.ExecuteReader()
   
   while ($reader.Read()) {
       Write-Output $reader.GetName(0) + ": " + $reader.GetValue(0)
   }
   
   $connection.Close()
   

   Note: Replace yourUsername, yourPassword, yourDatabase, and yourTable with appropriate values.

4. Run the PowerShell script:

   .\yourScript.ps1
   

Conclusion: By following the steps outlined in this article, you should be able to resolve issues when using MySQL.NET Connector PowerShell to query a database with connector versions 9.1 and 8.0.33, while ensuring insecure ciphers are disabled.
