This is certainly an old topic, but I always forget how to compile PGP 2.6.2 on GNU/Linux. Grab the source from MIT, probably, is what you want. You may also want to consider gpg. Much has changed since 1994! PGP 2.6.2 is particularly interesting for keeping password files using conventional encryption. It is possible to unencrypt the file temporarily using the -f option, so you don't have unencrypted files laying around with your passwords in it. Let's extract the source:
root@srv-1 pgp262 # ls
pgp262s.tar.gz
root@srv-1 pgp262 # tar -xzf *.gz
root@srv-1 pgp262 # ls
pgp262s.tar.gz pgp262si.tar.asc rsaref.tar.asc
pgp262si.tar rsaref.tar setup.doc
root@srv-1 pgp262 #
|
Read all of the docs and stuff, verify your source distribution if you wish, and uncompress the two tar files:
root@srv-1 pgp262 # tar -xf rsaref.tar
root@srv-1 pgp262 # tar -xf pgp262si.tar
root@srv-1 pgp262 # ls
config.txt fr.hlp pgp.hlp readme.doc rsaref.tar.asc
contrib keys.asc pgp262s.tar.gz rsalicen.txt setup.doc
doc language.txt pgp262si.tar rsaref src
es.hlp mitlicen.txt pgp262si.tar.asc rsaref.tar vmsbuild
root@srv-1 pgp262 #
|
You need to go into rsaref first and compile:
root@srv-1 rsaref # cd install
root@srv-1 install # ls
dos mac unix vax
root@srv-1 install # cd unix
root@srv-1 unix # ls
global.h makefile
root@srv-1 unix #
root@srv-1 unix # make
gcc -I. -I../../source/ -I/usr/include -O -c -DPROTOTYPES=1
.
.
.
c.o r_keygen.o r_random.o r_stdlib.o
ar: creating rsaref.a
ranlib rsaref.a
root@srv-1 unix #
|
Now, go back in to the src directory. You need to edit the makefile:
linux:
$(MAKE) all ASMDEF=-DSYSV CC=gcc LD=gcc OBJS_EXT="_80386.o _zmatch.o" \
CFLAGS="$(RSAINCDIR) -O6 -g3 -DUNIX -DIDEA32 -DASM"

For more info on this see this news post.
Let's compile:
onfig.c keyadd.h more.h r3kd.s vaxcrtl.opt zunzip.h
config.h keymaint.c mpiio.c random.c zbits.c
crypto.c keymaint.h mpiio.h random.h zdeflate.c
crypto.h keymgmt.c mpilib.c randpool.c zfile_io.c
descrip.mms keymgmt.h mpilib.h randpool.h zglobals.c
root@srv-1 src # make linux
make all ASMDEF=-DSYSV CC=gcc LD=gcc OBJS_EXT="_80386.o _zmatch.o" \
CFLAGS="-I../rsaref/source -I../rsaref/test -DUSEMPILIB -O6 -g3 -DUNIX
.
.
.
gcc -I../rsaref
.
.
.
_80386.o _zmatch.o ../rsaref/install/unix/rsaref.a
make[1]: Leaving directory `/usr/local/pgp262/src'
root@srv-1 src #

Let's run it:
root@srv-1 src # ./pgp -h

Pretty Good Privacy(tm) 2.6.2 - Public-key encryption for the masses.
(c) 1990-1994 Philip Zimmermann, Phil's Pretty Good Software. 11 Oct 94
Uses the RSAREF(tm) Toolkit, which is copyright RSA Data Security, Inc.
Distributed by the Massachusetts Institute of Technology.

Usage summary:
To encrypt a plaintext file with recipent's public key, type:
pgp -e textfile her_userid [other userids] (produces textfile.pgp)
To sign a plaintext file with your secret key:
pgp -s textfile [-u your_userid] (produces textfile.pgp)
To sign a plaintext file with your secret key, and then encrypt it
with recipent's public key, producing a .pgp file:
pgp -es textfile her_userid [other userids] [-u your_userid]
To encrypt with conventional encryption only:
pgp -c textfile
To decrypt or check a signature for a ciphertext (.pgp) file:
pgp ciphertextfile [plaintextfile]
To produce output in ASCII for email, add the -a option to other options.
To generate your own unique public/secret key pair: pgp -kg
For help on other key management functions, type: pgp -k

We are ready to encrypt!
