           Summary: EncryptPassword returns different results to ASP.NET
    Classification: Mono
           Product: Mono: Class Libraries
           Version: SVN
          Platform: i386
        OS/Version: Windows XP
            Status: NEW
          Severity: Major
          Priority: P5 - None
         Component: Sys.Web

When calling encryptpassword within code, passing the same strings, the
returned encrypted string is not the same as when called by ASP.NET, which is
breaking authentication for my XMLMembershipProvider.

Reproducible: Always

Steps to Reproduce:

byte[] bytes = Encoding.Unicode.GetBytes(password); 
byte[] src = Convert.FromBase64String(salt); 
byte[] dst = new byte[src.Length + bytes.Length]; 
byte[] inArray = null; 
Buffer.BlockCopy(src, 0, dst, 0, src.Length); 
Buffer.BlockCopy(bytes, 0, dst, src.Length, bytes.Length); 
inArray = this.EncryptPassword(dst); 
ret = Convert.ToBase64String(inArray);
Actual Results:  
ret = djBUmb9Cq6ayvO/8EGsjqy8sQB4jbPLI2/M9Ug/LEHXedb18LaSE97iECU8Guk3j

Expected Results:  
ret = mP2HHtZsSt5XTW//GTMi3GZCyd6GycdMer4IKHDOwyKHYcNOCWwHL9aEdxOColWH

The encrypted passwords are created by sqlmembershipprovider, and sqlmembership
authentication works in both ASP and mono, but after exporting the encrypted
password and salt to xml (to create a databaseless version of the website)
authentication only works in ASP, and fails in mono.
