tinc - TCP Cipher method

Question

In tinc 1.0.x there is Cipher param which allows to set encryption for UDP packets. For TCP packets encryption method is not allowed to be changed http://www.tinc-vpn.org/pipermail/tinc-devel/2005-July/000256.html. What method is used for TCP encryption?

Answer 1

It uses Blowfish OFB as in this line in net_setup.c

myself->connection->outcipher = EVP_bf_ofb();

I dunno why author can not add this param to tinc.conf.
