Subject: Rename a couple of relay crypto functions to "tor1".
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=374840c8093eb8bec303e7cf6efef182800e9079;p=thirdparty%2Ftor.git

Rename a couple of relay crypto functions to "tor1".

(I've designated the existing encryption algorithm "tor1".
