Hi,


Can I define the crypt algorithm which is negotiate while handshake?

I want to write a Client-Server-application, which connection is SSL encryted.

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?


Hope it helps.

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.
