-   
-   AUTHOR:
-      cornfeedhobo
-   
-   OPTIONS:
-      -t type      Specifies the type of key to create. The possible values are "dsa", "ecdsa", "rsa", or "ed25519". (default: "ed25519")
-      -b bits      Specifies the number of bits in the key to create. Possible values are restricted by key type. (default: 2048)
-      -c curve     Specifies the elliptic curve to use. The possible values are 256, 384, or 521. (default: 256)
-      -n factor    Specifies the work factor, or "difficulty", applied to the key generation function. (default: 16384)
-      -f filename  Specifies the filename of the key file.
-      -a           Add the generated key to the running ssh-agent.

 ## Usage
 
- 1) Generate your keys
-    ```bash
-    keydgen -f deterministic_key
-    ls -lh deterministic_key*
-    ```
-    
- 2) Allow time to pass, hoping an emergency does not arise when you have no access to your keys ...
-    
-    _If_ the time comes where you need access but can't get to your keys, you can then obtain this
-    utility and re-generate, or even directly add your key to a running `ssh-agent`.
-    ```bash
-    keydgen -a
-    ```
-    
- 3) Profit!
