# mesg1.jpg, mesg2.jpg, mesg3.jpg are files used as messages. They are 
# approxamitely 500b, 1.1k and 7k long respectively. The program creates 3
# set of outputs corresponding to each message. The files outX.key maps 
# the time taken to generate keys against key size. The files outX.en
# maps the encryption time versus key size and outX.de maps the decryption
# time taken against the key sizes. X=1,2,3 stands for the different messages
# The outX.en,outX.de,outX.key files can be given as an input for graph plotting 
# programs. All values(time) are in milli seconds and key sizes are in bits.
