The Caesar Cipher is a wonderful encryption algorithm if you have got nothing to hide. Its strong points are that the cipher is very easy to break, and that everybody knows about it. No more worrying about lost keys!
- fix
shift
- print usage when used without arguments
- WONTFIX accept input without flags or command line flags
- remove ">" in front of output
- WONTFIX add subcommands: 'e' for 'encrypt', 'd' for 'decrypt'
- add config file
Julius 1.1.0

Imperial encryption
USAGE:
julius [OPTIONS]
FLAGS:
-h, --help Prints help information
-V, --version Prints version information
OPTIONS:
-c, --caesar <caesar> Encrypt with caesar shift
-k, --key <key> key phrase or file
-o, --output <output> file to write output to
-s, --shift <shift> shift to caesar your text with
-x, --xor <xor> Encrypt with xor
By default, julius
can be used to decipher classified text using ROT13:
$ julius -e ETTUBRUTE
> RGGHOEHGR
$ julius -e RGGHOEHGR
> ETTUBRUTE
If you give it a file path, julius
will read its input from the file. You can
specify your own secret shift using the -s/--shift
option. The encrypted contents of the file
will be written to stdout or to a file if one is specified using the -o/--output
option.
$ julius -s 5 -e ITSJUSTARABBIT
> NGGNPXNGQNJA
$ julius -s 5 -d NGGNPXNGQNJA -o message.txt
$ cat message.txt

Clone the repo:
$ git clone https://github.com/proprefenetre/rust-julius.git && cd rust-julius
Build and install julius
using cargo:
$ cargo build --release
$ cargo install
You might want to add ~/.cargo/bin
to you path, if it isn't already.
