# rot
__*rot*__ is a command-line utility to cipher and decipher text using the [Caesar Cipher](https://en.wikipedia.org/wiki/Caesar_cipher).
## Note
Using equals with options is required, otherwise `rot` may crash.
This is due to the lack of support of the YAML configuration ([this is fixed in `clap` 3.0.0](https://github.com/clap-rs/clap/issues/1426))
## Usage
### Encrypt a simple phrase
```bash
$ rot -c=13 "The troops are dead"
Gur gebbcf ner qrnq
```
### Decrypt a simple phrase
```bash
$ rot -d=13 "Gur gebbcf ner qrnq"
The troops are dead
```
### Try multiple combinations
#### Encrypt
```bash
$ rot -c=3,5,7,13 "The troops are dead"
Wkh wurrsv duh ghdg
Ymj ywttux fwj ijfi
Aol ayvvwz hyl klhk
Gur gebbcf ner qrnq
```
#### Decrypt
```bash
$ rot -d=3,5,7,13 "Gur gebbcf ner qrnq"
Dro dbyyzc kbo nokn
Bpm bzwwxa izm lmil
Znk zxuuvy gxk jkgj
The troops are dead
```
### Output to a file
```bash
$ rot -c=13 -o=output.txt "The troops are dead"
$ cat output.txt
Gur gebbcf ner qrnq
```
### Read from a file
```bash
$ rot -d=13 -f output.txt
The troops are dead
```
### Read from `stdin`
```bash
$ echo "The troops are dead" | rot -c=13 # implicit
Gur gebbcf ner qrnq
$ echo "The troops are dead" | rot -c=13 --stdin
Gur gebbcf ner qrnq
```
### Execute a blind brute force attack
```bash
$ rot -b "Gur gebbcf ner qrnq"
