How long would it take?

Could the NSA reverse PGP encryption on a message that was iencrypted with a 1264bit key? Do you think they could do this in a matter of hours? Why, or why not? How long would it take? What do you know that corroborates this? This is a genereic question, which I hope aeveryone who knows about this will attempt to answer. If this is not the right subject for the LIST, send replies via EMAIL to wesley@ctrvax.vanderbilt.edu Thanks
