Rijndael in class library (package) not available for .NET Core

Question

Please help me. Where to find the Rijndael Security Cryptography in .NET Core?

What dependency I must to include in my class library (Package) project?

Answer 1

The Rijndael implementation is not (yet) ported to .NET Core. You could use AES (which is a subset of Rijndael) using the System.Security.Cryptography.Algorithms package which targets netstandard1.3:

var aes = System.Security.Cryptography.Aes.Create();

Note: you should only add this package dependency to the netstandard1.3 TFM, as it exists in the core library of the full framework already:

"netstandard1.3": {
  "dependencies": {
    "System.Security.Cryptography.Algorithms": "4.2.0"
  }
}
