Starting in 1998 (I think) the PGP company run by Phil Zimmerman released the PGP SDK for Mac, Unix and Windows. This was a big event because it was the first time that comprehensive, high grade crytography became available to the average person.
Unfortunately, due to the buy out of PGP by Symantec that famous SDK is no longer available by any obvious source. There used to be links to it on Cryptome, but those links have been deleted.
Does anybody know how I can find the Mac version of the 2001 release of the PGP SDK (including source code)?
