I've had a quick review of the code and I can't see any reason why not, but I wouldn't recommend it. I would not consider an EC_KEY object that failed an EC_KEY_check_key call to be valid, and I would expect the library to make the same assumption. It is safer to have the public key present, and it is not difficult to do so. > I mean i will load only private key and use the curve.Will I be able > to sign the data? > and How can i load other parametes like a,b,g,n in to the object. > > If you are using a named curve (as you are in the code example you posted), you do not need to worry about the other parameters. These are incorporated into the definition of the named curve. Matt
