Hi First of all here is my configuration
Debian testing (quite up to date) Mono-1.0.1 (got the mono-1.0.1.tar.gz) I am trying to use libcrypt.so.2.3.2 with c#. This code has been working for quite a while but stopped to work now. here is a little sample program I wrote <snip> using System; using System.Text; using System.Security.Cryptography; using System.Web.Security; using System.Runtime.InteropServices; namespace CryptTest { class CryptTest { [DllImport ("crypt", EntryPoint="crypt", SetLastError=true)] private static extern string UnixCrypt(string text, string salt); [STAThread] static void Main(string[] args) { Console.WriteLine("have {0} args",args.Length); string arg = args[0]; Console.WriteLine("UnixEncrypting {0} : {1}",arg,UnixCrypt(arg,arg)); } } } </snip> When I try to run this with mono encrypt.exe rainer I get a NullReference Exception. I am a bit lost here since this code has been working beautifully for months. Either my debian upgraded its libcrypt version (which could easily be true) or upgrading to mono-1.0.1 introduced the problem (which is less likely since I remember having the same issue on mono-1.0). Here is a snipped of the trace .. . ENTER: (wrapper managed-to-native) PerfTest.PerfTest:UnixCrypt (string,string)([STRING:0x80f8fc0:rainer], [STRING:0x80f8fc0:rainer], ) .. . .

But the function is still here here is a snip of crypt.h <snip> /* Encrypt at most 8 characters from KEY using salt to perturb DES. */ extern char *crypt (__const char *__key, __const char *__salt) __THROW; </snip> so to me everything looks still fine but still it does not work. Can anyone help? _______________________________________________ Mono-list maillist - [EMAIL PROTECTED] http://lists.ximian.com/mailman/listinfo/mono-list
