Change the calling convention of the imported function to cdecl (I think the blowfish library is C or C++, right?). I learned this a while back when I was having the same problem after upgrading to .NET 4.0; it turns out that .NET 3.5 disables PInvoke debugging messages. Basically the parameters of that function are getting ordered incorrectly when they get passed to the native function... which means that the stack will get used up and throw an exception eventually, causing your server to crash.

I don't understand the theory behind the problem like Lateralus but I do know the solution to it.

Code:

public class Blowfish : IDisposable

And replace the DllImports with these:

Code:

[DllImport("libeay32.dll", CallingConvention = CallingConvention.Cdecl)]
        public extern static void CAST_set_key(IntPtr _key, int len, byte[] data);

        [DllImport("libeay32.dll", CallingConvention = CallingConvention.Cdecl)]
        public extern static void BF_ecb_encrypt(byte[] in_, byte[] out_, IntPtr schedule, int enc);

        [DllImport("libeay32.dll", CallingConvention = CallingConvention.Cdecl)]
        public extern static void BF_cbc_encrypt(byte[] in_, byte[] out_, int length, IntPtr schedule, byte[] ivec, int enc);

        [DllImport("libeay32.dll", CallingConvention = CallingConvention.Cdecl)]
        public extern static void CAST_cfb64_encrypt(byte[] in_, byte[] out_, int length, IntPtr schedule, byte[] ivec, ref int num, int enc);

        [DllImport("libeay32.dll", CallingConvention = CallingConvention.Cdecl)]
        public extern static void BF_ofb64_encrypt(byte[] in_, byte[] out_, int length, IntPtr schedule, byte[] ivec, out int num);

the calling convention in native code, you can specify a calling convention __cdecl, __stdcall etc, it's basically the way arguments are passed to a function when it's called on x86, it determines how args are pushed/popped onto stack and return value stored in eax etc, the difference between __cdecl and __stdcall is whether the caller or callee cleans up the stack .

so basicly you want to say :-

Code:

[DllImport("libeay32.dll" , CallingConvention = CallingConvention.Cdecl)]
