'Run Java Triple DES Code in .NET 6 MVC Application
I have a triple DES Encryption & Decryption Code written in JAVA language and I want to run it using my.NET Core MVC Application, how can I do that. How can I integrate JAVA Code in my .NET Core MVC Application? Can someone please help me with this? I researched somewhat and found a library ikvm but it was also a dead end. Thank you
