RSA Encryption using C

This program encrypts/decrypts given text file using RSA asymmectric algorithm.

About Project

• RSA algorithm uses two big (100 digit) prime numbers to generate Public and Private key
• For computation GMP Library (GNU Multiple Precision Arithmetic Library) is used
• For genrating prime Miller-Rabin algorithm is used
• This Program takes input as text file from user and encrypts data and also saves Private Key in another file
• Using Private Key User can decrypt data again

Usage

$ make
• For Help
$ ./program -h

• For Encryption
$ ./program -e filename1 filename2 filename3

• For Decryption
$ ./program -d filename1 filename2 filename3
