What is the equivalent of Python pbkdf2 usage in C# for migrating password hashes -

we investigating options/scenarios credentials of 2 seperate sources (pyhton django application , asp.net application) can migrated single credential store. there many ways migrate, , 1 of them following: copy password hashes single store , based on property, choose validation method.

so i'm trying validate password hash generated in python django in c# console application.

i've found resources like: https://docs.djangoproject.com/en/1.10/_modules/django/contrib/auth/hashers/

and

https://docs.djangoproject.com/en/1.10/_modules/django/contrib/auth/hashers/pbkdf2

but have difficulties translating logic c#. think because cryptography skills aren't sufficient.

i hope can point me right direction on this.

update 1:

i'm testing following python django password hash:

pbkdf2_sha256$20000$t4fxlmzy8zre$x0hjgqggyaombqsfoobf/8nmlzgsk6stt8ke3meg6bm=  public bool verifypassword(string password, string hashedpassword, string salt) {     // password:  <test phrase>     // hashedpassword: x0hjgqggyaombqsfoobf/8nmlzgsk6stt8ke3meg6bm=     // salt: t4fxlmzy8zre      int iterationcount = 20000;      byte[] src = convert.frombase64string(hashedpassword);      byte[] inputpwhash;     using (var bytes = new rfc2898derivebytes(password, salt, iterationcount))     {          inputpwhash = bytes.getbytes(32);     }      var result = slowequals(src, inputpwhash);     return result; } 

what i've tried creating custom pbkdf2 implementation hmacsha256 digest.

public class rfc2898derivebytes : derivebytes, idisposable {     public rfc2898derivebytes(byte[] password, byte[] salt, int32 iterations)     {         _hmacsha256obj = new hmacsha256(password);         hlen = _hmacsha256obj.hashsize / 8;         _passwordbytes = password;         _saltbytes = salt;         _iterationcount = iterations;     } } 

and i'll match hashresult following way:

    public bool verifypassword(string password, string hashedpassword, string salt)     {         int iterationcount = 20000;          byte[] src = convert.frombase64string(hashedpassword);          byte[] inputpwhash;         using (var bytes = new rfc2898derivebytes(password, salt, iterationcount))         {             inputpwhash = bytes.getbytes(32);         }          var result = slowequals(src, inputpwhash);         return result;     } 

but hash results not same. need text encoding?
