Hello James, Right now I was writing a letter to you with the question regarding integration of openvpn and openssl 0.9.7 .:). I'll be glad to receive such patch because I need to integrate AES algorithm to openvpn (my boss requested this).
Thanks, in advance. Ildar. PS. Is the patch only for AES 256 and does not work for AES128 and AES192 ? ----- Original Message ----- From: "James Yonan" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Friday, May 03, 2002 7:09 PM Subject: OpenVPN and OpenSSL 0.9.7 was: Re: Integration of AES algorith to OpenSSL Crypto library > > > So, I need to know the process of integration of new cipher to Crypto > > > library. > > > I've tried to place the directory with new cipher (aes) inside of the > crypto > > > directory, > > > modified root Makefile.ssl and crypto/Makefile.ssl however it seems that > it > > > is not enough - > > > new codec does not appear in the list of supported codecs of openvpn > > > executable. > > > > Ask the author, James Yonan, he is around on this list. > > And with him around asking about EVP-problems I am would guess that > > he already nailed down the problem with 0.9.7. > > OpenVPN uses the cipher-independent EVP layer of OpenSSL as an interface to > the symmetric cipher algorithms.
