The public key is a BIGNUM type. I use the BN_bn2bin() function to convert it to a binary buffer and then send that buffer to the other side. On the other side I use BN_bin2bn() to convert it back to a BIGNUM type and put it back in the DH structure. > Thanks in advance, > Patrick Troy ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
