How to use 3des-file-encrypt.c
|
|
|
|
1) Start by typing make
|
|
2) Make a file to encode. Can be any file (ex. .txt .in .out .file etc.)
|
|
3) run the excecutable, for help run with -h flag. Basic command is as follows:
|
|
|
|
./3des-file-encrypt <-option> <KeySize> <input.file> <output.file>
|
|
|
|
KeySize examples: 56, 112, or 168
|
|
|
|
typing -e for option will encrypt the input.file onto the output.file.
|
|
typing -d for option will decrypt the input.file onto the output.file.
|
|
NOTE: When decrypting make sure the key is the same used for the
|
|
encryption, otherwise it won't decode correctly. Which is the idea.
|
|
Only those with the key will be able to decode the message. If no
|
|
key is entered into the command line, it will use "0123456789abcdef"
|
|
by default.
|
|
|
|
4) Running 'make clean' will delete the excecutable as well as any created
|
|
files. Making sure that the only files left are '3des-file-encrypt.c',
|
|
'Makefile', and 'README'.
