Re: RSA private key file problems

[Guillaume JOLIVET]

Hi,     If my KeyFile is not an ASCII (with characteres like key created by crypto++) file but a binary (hexadecimal) file, I can't use HexDecoder(). For the moment, I translate my binary key file into a ASCII file and next I do :       FileSource privFile(<myKeyFilePath>, true, new HexDecoder());     RSASSA_PKCS1v15_MD5_Signer priv(privFile);     - Does crypto++  work directly with binary files ? if yes, which class do I have to use ? - If not, is there a better way to do so?   Another question : - Does crypto++  check a certificate or a private key file ? If yes, how to do so ?   Thanks   Guillaume.     ----- Original Message ----- From: Guillaume JOLIVET To: [EMAIL PROTECTED] Sent: Tuesday, July 15, 2003 12:36 PM Subject: RSA private key file problems Hi all,   I would like to crypt data with a RSA with MD5 algorithm but I've got some problems. My private key file is a variable-size hexadecimal format file.   Here are my code lines :       FileSource privFile(<myKeyFilePath>, true, new HexDecoder());     RSASSA_PKCS1v15_MD5_Signer priv(privFile);     When I try to crypt, the program fails on the creation of  the RSASSA_PKCS1v15_MD5_Signer object. I think that the FileSource object is not correct because of the key file format, but I don't know what kind of object to use instead the HexDecoder object.     Does somebody got any idea,   Thanks, Guillaume.
