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\

Answer 1

For those who need it, .NET Framework 4.7.2 includes an overload of Rfc2898DeriveBytes that allows the hashing algorithm to be specified:

byte[] bytes;
using (var deriveBytes = new Rfc2898DeriveBytes(password, salt, iterations, HashAlgorithmName.SHA256))
{
    bytes = deriveBytes.GetBytes(PBKDF2SubkeyLength);
}

The HashAlgorithmName options at the moment are:

• MD5
• SHA1
• SHA256
• SHA384
• SHA512
