The length of the Key BLOB depends on its type. Take a look here: Base Provider Key BLOBs[^] But shouldn't the length equal the file length? You can obtain it using CFile's GetLength method after opening it. -- jlr http://jlamas.blogspot.com/[^]

Thnx for (late) reply but ive done it and through the same method as u told. Since Im stuck in cryptography stuff nad Im using CryptoAPI Ive some data of type BYTE* (PUBLICKEYBLOB)I want to write it in a file then send it across the network and then read from file and use that public key.SIGH!!!! now to write it in the file i covert BYTE* to CHAR* and then inverse to read ...but to dont get the same value back. Do u have any better idea to do this?? Thanx again for ur help.

You can just click the email button on my reply. I'll gladly look your project over, but I only have VC++6.0, so if you use VC.NET I can't help you. Cheers Steen.

by definition an octet is 8 "something". octet is the (better) french translation of a byte; maybe the original programmers were french. as for the other one, maybe we're missing < > Maximilien Lincourt Your Head A Splode - Strong Bad

Oops! v was meant to be the OCTETSTR parm, sorry. Change the function header to this: void OctetStrToHexString(OCTETSTR v, CString& sResult) -- jlr http://jlamas.blogspot.com/[^]

Move the includes for borzoi.h and nist_curves.h below the include for stdafx.h and try again. -- jlr http://jlamas.blogspot.com/[^]

I don't exacly get your point. Do you have all child dialogs visible at the same time, or is it DoModal() for each child dialog? If you are using DoModal() for each child, then get the data from each of them: CChild c; if (c.DoModal() == IDOK) { int a = c.m_Variable; //Do this for all variables you need. ... } this is this.

If you've designed it properly, my suggestion would be to simply click the Cancel button and then open the dialog up again. All of the initial (default) values will be present at that point and you will not have had to resort to some "reset" button.
