Another one of these? http://svn.haxx.se/tsvnusers/archive-2008-05/0103.shtml

What, exactly, is being "exported from the EU" here? TSVN's primary
developer(s) is located in Europe, but it uses code contributed by
thousands of people all over the world. It's mirrored on servers
around the world. Anyone can download it from just about anywhere, to
a computer just about anywhere.

It's all Open Source, so you can audit the code for yourself if the
answers aren't satisfactory.

No part of Subversion is used "solely" for these purposes.

Do you understand what this software is and does in the first place?
The authentication used is dictated by the server TSVN connects to,
which is either Apache (using Basic or Digest authentication,
potentially over SSL - so you'll need to chase up that tree, not
here), svnserve (which does not have any encryption at all), or
svnserve tunneled over SSH (in which case you want to be checking on
the encryption used by your SSH service, not Subversion or
TortoiseSVN).
