This web site is a submission for the <b> Web Mastery </b>
|
|
|
|
|
course held at Brighton University from the 15th of March to
|
|
|
|
|
the 19th of March 2003.

<h2> Course Assignment </h2>

|
|
A web based tool, to run through RSA encryption. This tool uses PHP
|
|
|
|
|
as a web server scripting language, which calls bash and bc scripts to
|
|
|
|
|
perform the mathematics of RSA. The intention is to produce an interactive
|
|
|
|
|
tutorial for RSA. Each stage in key generation and encryption is shown, with
|
|
|
|
|
(where practical) intermediate results.
|
|
|
|
|
<p>
|
|
|
|
|
This tool allows simulations of small RSA implementations. Even
|
|
|
|
|
with some algorithmic optimisation to the de-cryption routines
|
|
|
|
|
(see <a href=maths.html> maths of large exponents)</a>. If
|
|
|
|
|
simulations larger than 128 bits are simulated, the de-cryption
|
|
|
|
|
private key parts may take several minutes to calculate.
