        !             5: How to Install PGP
        !             6: ==================
        !             7: 
        !             8: The first question is, what platform are you on?
        !             9: 
        !            10: PGP 2.1 runs on several varieties of Unix, MS-DOS, VAX VMS, Ataris,
        !            11: Amigas, and possibly other operating systems.  Naturally, installation
        !            12: instructions differ depending on your hardware.  Separate instructions
        !            13: are provided here for MSDOS and Unix.
        !            14: 
        !            15: No matter what the machine you are on, though, do this...
        !            16: 
        !            17: STEP 1:
        !            18: READ THE DOCUMENTATION.  At least read Volume I of the PGP User's
        !            19: Guide.  Cryptography software is easy to misuse, and if you don't use
        !            20: it properly much of the security you could gain by using it will be
        !            21: lost!  You might also be unfamiliar with the concepts behind public
        !            22: key cryptography; the manual explains these ideas.  Even if you are
        !            23: already familiar with Public Key Cryptography, it is important that
        !            24: you understand the various security issues associated with using
        !            25: PGP.  It may not be important to read the fine print on a box of
        !            26: breakfast cereal, but it may be crucial to read the label of a
        !            27: prescription drug.  Cryptography software is like pharmaceuticals-- 
        !            28: so read the manual!
        !            29: 
        !            30: See the section below for your system's particular installation
        !            31: instructions.
        !            32: 
        !            33: If you do not have any of these systems, you will either have to port
        !            34: the sources to your machine or find someone who has already done so.
        !            35: 
        !            36: ######################################################################
        !            37: For MSDOS:
        !            38: 
        !            39: PGP is distributed in a compressed archive format, which keeps all
        !            40: the relevant files grouped together, and also saves disk space and 
        !            41: transmission time.
        !            42: 
        !            43: The current version, 2.1, is archived with the PKZIP utility, and the
        !            44: PGP executable binary release system is in a file named PGP21.ZIP.
        !            45: This contains the executable program, the user documentation, and a
        !            46: few keys and signatures.  There is also a second file available
        !            47: containing the C and assembly source code, called PGP21SRC.ZIP; unless
        !            48: you are a programmer interested in cryptography, it is probably of
        !            49: little interest to you.  It may or may not be available from the
        !            50: source from which you get PGP21.ZIP; if not, and you want it, see the
        !            51: Licensing and Distribution section of the PGP User's Guide.
        !            52: 
        !            53: You will need PKUNZIP version 1.1 or later to uncompress and split
        !            54: the PGP21.ZIP archive file into individual files.  PKUNZIP is
        !            55: shareware and is widely available on MSDOS machines.
        !            56: 
        !            57: Create a directory for the PGP files.  For this description, let's
        !            58: use the directory C:\PGP as an example, but you should substitute
        !            59: your own disk and directory name if you use something different. 
        !            60: Type these commands to make the new directory:
        !            61: 
        !            62:    c:
        !            63:    md \pgp
        !            64:    cd \pgp
        !            65: 
        !            66: Uncompress the distribution file PGP21.ZIP to the directory.  For
        !            67: this example, we will assume the file is on floppy drive A - if not,
        !            68: substitute your own file location.
        !            69: 
        !            70:    pkunzip a:pgp21
        !            71: 
        !            72: 
        !            73: Setting the Environment
        !            74: -----------------------
        !            75: 
        !            76: Next, you can set an MSDOS "environment variable" to let PGP know
        !            77: where to find its special files, in case you use it from other than
        !            78: the default PGP directory.  Use your favorite text editor to add the
        !            79: following lines to your AUTOEXEC.BAT file (usually on your C: drive):
        !            80: 
        !            81:    SET PGPPATH=C:\PGP
        !            82:    SET PATH=C:\PGP;%PATH%
        !            83: 
        !            84: Substitute your own directory name if different from "C:\PGP".
        !            85: 
        !            86: Another environmental variable you should set in MSDOS is "TZ", which
        !            87: tells MSDOS what time zone you are in, which helps PGP create GMT
        !            88: timestamps for its keys and signatures.  If you properly define TZ in
        !            89: AUTOEXEC.BAT, then MSDOS gives you good GMT timestamps, and will
        !            90: handle daylight savings time adjustments for you.  Here are some
        !            91: sample lines to insert into AUTOEXEC.BAT, depending on your time
        !            92: zone:
        !            93: 
        !            94: For Los Angeles:  SET TZ=PST8PDT
        !            95: For Denver:       SET TZ=MST7MDT
        !            96: For Arizona:      SET TZ=MST7
        !            97:    (Arizona never uses daylight savings time)
        !            98: For Chicago:      SET TZ=CST6CDT
        !            99: For New York:     SET TZ=EST5EDT
        !           100: For London:       SET TZ=GMT0BST
        !           101: For Amsterdam:    SET TZ=MET-1DST
        !           102: For Moscow:       SET TZ=MSK-3MSD
        !           103: For Aukland:      SET TZ=NZT-13
        !           104: 
        !           105: Now reboot your system to run AUTOEXEC.BAT, which will set up 
        !           106: PGPPATH and TZ for you.
        !           107: 
        !           108: 
        !           109: 
        !           110: Generating Your First Key
        !           111: -------------------------
        !           112: 
        !           113: One of the first things you will want to do to really use PGP (other
        !           114: than to test itself) is to generate your own key.  This is described
        !           115: in more detail in the "RSA Key Generation" section of PGP User's
        !           116: Guide.  Remember that your key becomes something like your written
        !           117: signature or your bank card code number or even a house key - keep it
        !           118: secret and keep it secure!  Use a good, unguessable pass phrase and
        !           119: remember it.  Right after you generate a key, put it on your key
        !           120: rings and copy your secret keyring (SECRING.PGP) to a blank floppy
        !           121: and write protect the floppy.  
        !           122: 
        !           123: After you generate your own key pair, you can add a few more public
        !           124: keys to your key ring.  A collection of sample public keys is
        !           125: provided with the release in the file KEYS.ASC.  To add them to your
        !           126: public key ring, see the PGP User's Guide, in the section on adding
        !           127: keys to your key ring.
        !           128: 
        !           129: 
        !           130: ######################################################################
        !           131: For UNIX:
        !           132: 
        !           133: You likely will have to compile PGP for your system; to do this, first
        !           134: make sure the unpacked files are in the correct unix textfile format
        !           135: (the files in pgp21src.zip are in MSDOS CRLF format, so for unix you
        !           136: must unpack with "unzip -a").  Then copy the file "makefile.unx" in the
        !           137: distribution to "Makefile".
        !           138: 
        !           139: If you don't have an ANSI C compiler you will need the unproto package
        !           140: written by Wietse Venema.  unproto was posted on comp.sources.misc and
        !           141: can be obtained from the various sites that archive this newsgroup
        !           142: (volume 23: v23i012 and v23i013) or ftp.win.tue.nl file:
        !           143: /pub/programming/unproto4.shar.Z  Read the file README in the unproto
        !           144: distribution for instructions on how to use unproto.  The unix makefile
        !           145: for pgp (makefile.unx) contains a few targets for compliling with
        !           146: unproto, these assume you have unpacked unproto in a subdirectory
        !           147: "unproto" in the pgp "src" directory.
        !           148: 
        !           149: 
        !           150: Then...
        !           151: 
        !           152: type:
        !           153:   "make sungcc"   for Sun with GNU gcc
        !           154:   "make suncc"    for Sun with cc and unproto
        !           155:   "make sysv_386" for SVR4 386 with asm primitives
        !           156:   "make x286"     for XENIX/286 with asm primitives and unproto
        !           157:   "make ultrix"   for DEC 4.2BSD Ultrix with gcc
        !           158:   "make rs6000"   for RS6000 AIX
        !           159: 
        !           160: There are more targets in makefile.unx.  If your system doesn't have
        !           161: a target in makefile.unx you will have to edit the makefile, make
        !           162: sure you compile for the correct byte order for your system: define
        !           163: HIGHFIRST if your system is big-endian (eg. Motorola 68030).
        !           164: There are also some platform-specific parameters in the include file
        !           165: "platform.h".  Some platforms may have to modify this file.
        !           166: 
        !           167: If all goes well, you will end up with an executable file called "pgp".
        !           168: 
        !           169: Before you install pgp, run these tests:
        !           170: (do not create your real public key yet, this is just for testing pgp)
        !           171: 
        !           172: - create a public/secret key pair (enter "test" as userid/password):
        !           173:        pgp -kg
        !           174: 
        !           175: - add the sample keys from the file "keys.asc" to the public keyring:
        !           176:        pgp -ka keys.asc
        !           177:   pgp will ask if you want to sign the keys you are adding, answer yes
        !           178:   for at least one key.
        !           179: 
        !           180: - do a keyring check:
        !           181:        pgp -kc
        !           182: 
        !           183: - encrypt pgpdoc1.txt:

        !           185: 
        !           186: - decrypt this file:
        !           187:        pgp testfile.pgp
        !           188: 
        !           189: this should produce the file "testfile" compare this file with pgpdoc1.txt
        !           190: 
        !           191: If everything went well, install pgp in a bin directory.
        !           192: 
        !           193: Place the documentation, pgpdoc1.txt and pgpdoc2.txt somewhere where
        !           194: you can reasonably read it; since it's for you, not the software, the
        !           195: location doesn't really matter.
        !           196: 
        !           197: Place the man page (pgp.1) in an appropriate spot.  If you don't know
        !           198: anything about how man pages work, you can make the man page look
        !           199: human readable yourself by typing "nroff -man pgp.1 >pgp.man" and
        !           200: reading "pgp.man".
        !           201: 
        !           202: Create a subdirectory somewhere in your home directory hierarchy to
        !           203: hold your public and private key rings and anything else pgp might
        !           204: need (like the language.txt file).  You must set the environment
        !           205: variable "PGPPATH" to point to this place before you use the system.
        !           206: Copy the files "language.txt", "config.txt", and the ".hlp" files from
        !           207: the distribution into this subdirectory.
        !           208: 
        !           209: IMPORTANT: THIS DIRECTORY CANNOT BE SHARED!  IT WILL CONTAIN YOUR
