# Web Mastery Course : Assignment Work

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

This is the course work submission for R.P. Clark (part time student).

## Course Assignment

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.

This tool allows simulations of small RSA implementations. Even with some algorithmic optimisation to the de-cryption routines (see maths of large exponents). If simulations larger than 128 bits are simulated, the de-cryption private key parts may take several minutes to calculate.
