/*
|
|
There is some strangeness going on here. It looks like algorithms
|
|
at the end take some kind of penalty. For example, running the RW tests
|
|
first got a result of:
|
|
RW-1024: 148.14 ms / private operation
|
|
but running them last output:
|
|
RW-1024: 363.54 ms / private operation
|
|
|
|
I think it's from memory fragmentation in the allocators, but I'm
|
|
not really sure. Need to investigate.
|
|
|
|
Until then, I've basically ordered the tests in order of most important
|
|
algorithms (RSA, DSA) to least important (NR, RW).
|
|
|
|
This strange behaviour does not seem to occur with DH (?)
|
|
|
|
To get more accurate runs, use --bench-algo (RSA|DSA|DH|ELG|NR); in this
|
|
case the distortion is less than 5%, which is good enough.
|
|
|
|
We do random keys with the DL schemes, since it's so easy and fast to
|
|
generate keys for them. For RSA and RW, we load the keys from a file. The
|
|
RSA keys are stored in a PKCS #8 structure, while RW is stored in a more
|
|
ad-hoc format (the RW algorithm has no assigned OID that I know of, so
|
|
there is no way to encode a RW key into a PKCS #8 structure).
