cryptography - Rfc2898 / PBKDF2 with SHA256 as digest in c#

Question

I want to use Rfc2898 in c# to derive a key. I also need to use SHA256 as Digest for Rfc2898. I found the class Rfc2898DeriveBytes, but it uses SHA-1 and I don't see a way to make it use a different digest.

Is there a way to use Rfc2898 in c# with SHA256 as digest (short of implementing it from scratch)?

Answer 1

.NET Core has a new implementation of Rfc2898DeriveBytes.

The CoreFX version no longer has the the hashing algorithm hard-coded

The code is available on Github. It was merged to master on March 2017 and has been shipped with .NET Core 2.0.
