I know that Lotus Development, until just recently, had domestic and
international versions of their Lotus Notes/Domino groupware/messaging
system software. The domestic version had 64 (or perhaps 128; I do not
recall exactly) bit encryption; the international had 56 bit, but I know
they did a key-escrow on 16 bits, so the effective encryption was down to
40-bit (ie, the same as Microsoft and Netscape).
They too, now have only one version (well, one with two subtypes, because
of French and Iraqi restrictions on encryption software), and I think it
is the 64 (or 128-bit) version.
As an aside, the British now have a law that requires users to turn over
encryption keys and passwords for encryption keys on demand by the British
government, so the size of the key really is immaterial in the UK.
