- Hmm... I've heard (rumours, rumours...) that thre is an exportable
- version of MailSafe, which is limited to 512 (or was it 540?) bit keys
- (or was it moduli?)... Does that mean that NSA can factor such
- numbers?... Would be a pretty serous advancement in mathematics, not
- just in cryptography... It would also mean that they find cracking the
- key easier than the other forms of attack... Could somebody in the USA
- check that there is indeed an exportable version of MailSafe and see
- what the max key size is?
