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: [1].

I've spent two substantial chunks of my career as a teacher — 1978-83 and now 2002-2008 — 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.

I'll be on vacation most of January with limited computer access, probably doing almost no work here.
