One interesting thing about S3 C++ SDK is that it can read file multiple
times for calculating checksums and signature, but the last is not done
for the https protocol, though the checksum "could".
And indeed it does, since default checksum algorithm (MD5) does not
support streaming, and so it always calculated, regardless of the
protocol, however everything else (CRC*/SHA*) supports streamming and
actually will not be calculated for https at all!
This will be fixed in the follow up patch.
