Cryptster

=========

A simple library to implement basic ciphers

It currently supports the ROT13 cipher (similar). Well actually it just adds 13 to the input.

Repo: https://github.com/Triztian/cryptster

## Usage

### Ciphering a string

```

$ cryptster -c "ROT13" -t "Hello"

```

### Ciphering the file content

```

$ cryptster -c "ROT13" -f "file-with-content.txt"

```

### Ciphering a string and writing the ciphertext into a file

```

$ cryptster -c "ROT13" -t "Hello" -o "my-secret-file.rot13"

```

### Unciphering a string

```

$ cryptster -d -c "ROT13" -t "Uryy|"

```

### Unciphering a file

```

$ cryptster -d -c "ROT13" -f "my-secret-file.rot13" 

```

## Symmetric Key Ciphering

### AES (Rijndael)

To use the AES encryption you should provide a 16 char length key string.

```

$ cryptster -k "1234567890abcdef" -c AESCBC128 -t "My secret message" 

```
