Use this to generate password hashes from plaintext that match those generated by the algorithm shipped in ASP.NET Identity v3.
dotnet tool install -g jkulubya.dotnet.hash-identity
$ dotnet hash-identity <text to hash as ASP.NET v3 password>
I got tired of going through the reset password flow of the apps I was developing whenever I had to change a password. Now I just run this and update the password field in the database.
Take care what passwords you input into this tool, because they get saved into your terminal's history.
This tool should get no where near a production machine/database/service/whatever.
