Well, encryption undoubtedly _is_ used by terrorists. At least
occasionally, eg when they visit ATMs or do internet shopping.
Encryption may well also be used by terrorists for more direct terrorist
purposes, though that use doesn't actually seem to be widespread (and
those who do seem to be at the cleverer end of the spectrum, and won't
be put off by a law demanding backdoors - everybody who has made even a
cursory study of the field knows how to do unbreakable end-to-end
However, what I am interested in, which should perhaps be emphasised a
bit more, is the use of encryption by ordinary folk who are not
terrorists, for lawful purposes.
So, what is encryption good for?
protection against identity theft
use by enterprises keep customer details confidential
keep mobile calls private
modern car locks
conditional access to computers, databases etc - anything needing a password
