RC-Crypt is a program to keep your data safe.
(See www.distributed.net for details of how long it took thousands of computers worldwide to crack a 64 bit key when the initial content of the data was known.)
It has a multitude of options making it very suitable for inclusion into complex scripts.
How to use this program.
1. Compile it.
The program uses glibc, so make sure that is installed on your system. A Makefile has been created, that will allow you to build it using
If you wish to add options, feel free to do so
2.Copy both the rccrypt and the rcc program to somewhere you can run it.
Find the places you could copy it to using
(It is likely you will need root access for most of these.)
3. Use it.
rccrypt will encrypt or decrypt the input given to it according to the rc5 Algorithm as described by RSA Laboratories.
This is the syntax of the program:
rccrypt [-d] [-p] [ -r rounds] [-k key | -f file | -e env_var] [-i infile] [-o outfile] [-w]
