Hi,
I kept suggesting the above, because long ago I wrote this code in dsage:
-------------
if os.uname()[0] != 'Darwin' and cmd_exists('openssl'):
# We use openssl by default if it exists, since it is *vastly*
# faster on Linux.
cmd = ['openssl genrsa > %s' % privkey_file]
print "Using openssl to generate key"
print cmd[0]
subprocess.call(cmd, shell=True)
-------------
So I thought people were having issues with slow keys since they
didn't have openssl installed. That's why I suggested installing it.
However, I just checked and the above code evidently mysteriously
morphed into the following several months ago:
-------------
if False and os.uname()[0] != 'Darwin' and cmd_exists('openssl'):
# We use openssl by default if it exists, since it is *vastly*
# faster on Linux.
cmd = ['openssl genrsa > %s' % privkey_file]
print "Using openssl to generate key"
print cmd[0]
subprocess.call(cmd, shell=True)
else:...
-------------
I'm guessing somebody tested certtool on one platform where they got
lucky and certtool seemed to actually work in a reasonable amount of
time, and concluded the issue was fixed. Nope.
Please referee
http://trac.sagemath.org/sage_trac/ticket/7800
which reverts this behavior, switching back to using openssl if available.
