User:Sandy Harris

I'm a baby-boomer Canadian currently teaching English and IT subjects in China. My academic qualifications are a BA in Psychology and a Certificate in Teaching English as a Second Language, both from Carleton U in Ottawa. I am quite active on Wikitravel, where I'm an admin, and sometimes contribute to other wikis. See my Wikitravel user page:.

I've spent two substantial chunks of my career as a teacher &mdash; 1978-83 and now 2002-2008 &mdash; mainly because that is a good way to support travel. At other times I've worked in computing, mostly as a technical writer but a bit of everything else too.

I wrote most of the documentation for the FreeS/WAN project, a Linux implementation of the IPsec encryption protocols. I have permission to re-use that text here User_talk:Sandy_Harris/Permission.

I'm interested in computer security and cryptography. I think my latest paper, on combining stream ciphers and block ciphers, is fairly interesting.
