- Encryption Software
-
- Ssshhh... John Kennedy will say this only once...
-
-
- Heard of the clipper chip? It's the US government backed
- cryptography system which they want every one to use. It's
- extremely secure, but not to the US government who designed
- a back door into it, and are therefore able to crack it.
-
- Not everyone is happy with this arrangement, and there are
- several programs which use the so-called 'public key'
- methods for encoding messages. In fact, government agencies
- don't like this (they like to know what's going on - but only
- for our own good, of course) and tend to get shirty when
- someone writes a program that they can't crack.
-
- The most famous of these programs is PGP (Pretty Good
- Privacy), which is available on a wide variety of computer
- platforms. There are commercial programs which will achieve
- the same aim (with better and worse results), and now there
- is one for the Amiga.
-
- The program doesn't actually have a name (it's known as
- RSRSA20 to its friends), and it requires an Amiga with a
- 68020 or better and a printer in order to operate.
-
- As far as the documentation goes... oh dear. The spiral
- bound tome bears an uncanny resemblance to a university
- thesis, even going so far as to have some photocopied
- performance graphs included at the back.
-
- The text is a shambles of cryptic anecdotes, general notes
- of security, sometimes contradictory ramblings and an
- extremely poor tutorial section. There is no denying that
- sections makes a very interesting read, but as an
- instruction book for a software package it sucks. For a
- product which is designed to make encryption a tool for
- business and personal use, it falls flat on it's face.
- Students of cryptology will find it both fascinating and
- frustrating - there are no reference or bibliography
- sections.
-
- The software is tediously written to ignore all the niceties
- of the Amiga operating system, and instead of a Windows,
- menus and requestors based system opens a single un-movable
- window, driven solely by function key presses. In use it is
- un-necessarily complicated.
-
- However, this isn't an arcade game which requires flashy
- graphics - it's a tool for taking a text file and ensuring
- no-one else can read it. It is (apparently) an
- implementation of the Rivest-Shamir-Adleman algorithm, which
- means it offers a Class B security system; "uncrackable by
- any large multi-national company, but might be broken by a
- national intelligence agency prepared to commit several
- months and £50,000+ to the task". The author can provide a
- Class A system if required for additional cost. The software
- costs £200 for the Class B system, and £500 for a Class A
- system.
-
- Now, here I have a problem. There is simply no way that I
- can test if the claims of this program are correct. Like the
- author, I have a masters degree (I wonder if he got his in
- cryptology with this as his thesis?), but unfortunately mine
- is not in mathematics. To sit down and work through the
- appendix on number theory would take me a while, and at the
- end of it I still have no guarantee that the program is actually
- based on the maths.
-
- On the other hand, to the best of my knowledge at least, the
- author seems to know what he is talking about. He claims
- that the program is one of the most powerful software based
- systems available to the public, and also hints that dark
- forces (that is, Scotland Yard) may be interested in his
- plans - so obviously you should buy now before you need to
- arrange visiting rights.
-
- The public domain program PGP is probably adequate for
- anything that I will need to send, but if you do need to
- move sensitive material around, contact the author.

-
- Whether due to paranoia, or a genuine desire to maintain
