sslutil: calculate host fingerprints from additional algorithms
Currently, we only support defining host fingerprints with SHA-1.
A future patch will introduce support for defining fingerprints
using other hashing algorithms. In preparation for that, we
rewrite the fingerprint verification code to support multiple
fingerprints, namely SHA-256 and SHA-512 fingerprints.
We still only display the SHA-1 fingerprint. We'll have to revisit
this code once we support defining fingerprints with other hash
functions.
As part of this, I snuck in a change to use range() instead of
xrange() because xrange() isn't necessary for such small values.
