Cipher algorithm
Hi, I want to write a Client-Server-application, which connection is SSL encryted. Can I define the crypt algorithm which is negotiate while handshake? Is there a crypt algorithm which does not change the size of the data? thanks in advance Markus Wenke __ OpenSSL Project http://www.openssl.org User Support Mailing Listopenssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]

I'll cite it once more (see also the archive at http://marc.theaimsgroup.com/?l=openssl-usersm=115882610217857w=2): Hi, I want to write a Client-Server-application, which connection is SSL encryted. Can I define the crypt algorithm which is negotiate while handshake? See http://www.openssl.org/docs/ssl/SSL_CTX_set_cipher_list.html Is there a crypt algorithm which does not change the size of the data? Hmm, what is the background of this question? In principle encryption does not necessarily change the size of the data, but there is protocol overhead and padding, so in reality you will have to pay for encryption with bigger data, independent of the used algorithm. This is especially relevant when transmitting small chunks of data at a time, if you are sending Megabytes of data in quick succession I'd guess that the overhead is negligible. Hope it helps.

How can I insert another cipher algorithm into OpenSSL library?
Hi~ I have a question How can I insert another cipher algorithm into OpenSSL library? I want to use SEED algorithm(Korean standard cipher) in OpenSSL library... Somebady help me please :-) Have a nice day~
