        I don't think it was hampered outside of the US (with the possible
exception of Canada) either since once it was outside the US, the US
export rules were not an issue either. Once outside the US, it spred
like wildfire. What was hampered was the exporting of the code to
begin with. That they later accomplished by publishing in a book and
legally sending THAT outside the country where it was scanned in and
then compiled. That took time, but time is all it was. Even before then
(the 2.x days) we had the international version of PGP (pgpi). The
export regs were not the problem (much to the embarrasement of the US

        PGP was hampered more by itself and its complex archane interface
more than anything else. RSA couldn't stop it or even slow it down
(and certainly not outside the US where the RSA algorithm wasn't patented).
The US government couldn't slow it down once it got outside the US
borders. The PGP interface was it's own worse enemy.
