I can deliver it to you in a day. I have 5+ year of experience in dotnet application. Here is how it can be done: The general best practice for symmetric encryption is to use Authenticated Encryption with Associated Data (AEAD), however this isn't a part of the standard .net crypto libraries. So we can use AES256 and then HMAC256, a two step Encrypt then MAC, which requires more overhead and more keys. Other way is the simpler practice of AES256-GCM using the open source Bouncy Castle (via nuget). And accordignly we can decrypt the same. I hope you would consider my bid. Thanks

Hello, I can create that program for you. I worked on mesuring execution time of c# projects. I can make it so it gives you numbers and/or text file with measure times. Did you wanted user interface or it can be done from command shell (cmd)? I hope we will work together on this project

I have over 8+ years of experience using C# for WinForms, WPF, Console and Xbox. I have created many encryption libraries of my own over the years and am very good at documenting source code and building a clean, intuitive UI. I wanted to create this encryption program for you and allow you to have some options for the output, such as what time unit you want the results in, how many characters, spaces and so on in the document. I can also have this done very fast, efficiently and professionally. I expect this to take me 2 hours total and can provide source code in C# for Console, WinForms or WPF. I'll also let you select which version of Visual Studio you want the project file for. I also fully document every line of source code using web and API references to help you even further. I can provide you with my contact info so if you need help any time after, it's free! Please feel free to message me if you have any questions or concerns!
