I have an encrypted "RSA PRIVATE KEY" ".key" RSA PKCS#1 key (which I understand from here) does not include a key type OID).
I also have the password to decrypt it. I am using it to create an encrypted and signed URL.
I have managed to get the code working locally, but now I need to figure how to secure it on an Azure web app (I'm using C# MVC 5 with .NET Framework 4.6 and a SQL Server back end). I was helped along by this great post, but it is an older link that either I can't figure out how to use or it's longer valid. Azure seems to only allow me to upload a .pfx file.
