ftp.pgp.net is a conglomeration of several machines. Right now (January 1998) there are fully functioning nodes in Austria, Australia, Switzerland, Germany (four sites, in Hamburg, Paderborn, Berlin and Erlangen), France, Japan, Norway, Poland, Sweden, Taiwan and the United Kingdom (two sites, in Cambridge and Oxford).
contain various PGP-related materials.
The latest PGP source code and binaries for various major architectures will be found in directories named after the release of PGP, in the directory pgpi which is mirrored from ftp://ftp.no.pgpi.com/pub/pgpi e.g. 2.x, 5.0 and 5.5
Older versions are in the directory OLD in subdirectories called pc, mac, amiga, archimedes, atari, vax-vms and unix though the latter is a bit of a misnomer since the generic 2.x source code distribution will be found there. Under pc will be found MS-DOS and OS/2 versions and MS-Windows front-ends.
Other directories contain help-files for several languages (in language); documentation (in doc); the published key ring (in keys) and a number of front-ends, utility programs and the PGPTools library (in utils). A full listing of files in the archive are held in ls-lR.Z.
