## Usage
Reads a tox profile and prints out information on what's in there to stderr.
Call it with one argument, the filename of the profile for the decrypt or info
commands, or the filename of the nodes file for the nodes command.
Call it with one argument, the filename of the profile for the decrypt, edit
or info commands, or the filename of the nodes file for the nodes command.
3 commands are supported:
1. ```--command decrypt``` decrypts the profile and writes to the result
@ -52,13 +52,24 @@ Optional arguments:
```info``` will output the profile on stdout, or to a file with ```--output```
Choose one of ```{info,repr,yaml,json,pprint}```
Choose one of ```{info,repr,yaml,json,pprint,save}```
for the format for info command.
Choose one of ```{nmap_udp,nmap_tcp}```
to run tests using ```nmap``` for the ```DHT``` and ```TCP_RELAY```
sections of the profile. Reguires ```nmap``` and uses ```sudo```.
#### Saving a copy
The code now can generate a saved copy of the profile as it parses the profile.
Use the command ```--command info --info save``` with ```--output```
and a filename, to process the file with info to stderr, and it will
save an copy of the file to the ```--output``` (unencrypted).
It may be shorter than the original profile by up to 512 bytes, as the
original toxic profile is padded at the end with nulls (or maybe in the
decryption).
### --command nodes

Decrypt a profile.
### --command edit
The code now can generate an edited copy of the profile.
Use the command ```--command edit --edit section,key,val``` with
```--output``` and a filename, to process the file with info to stderr,
and it will save an copy of the edited file to the
```--output``` file (unencrypted). There's not much editing yet; give
```--command edit --edit help``` to get a list of what Available Sections,
and Supported Quads (section,num,key,type) that can be edited.
Currently it is:
```
NAME,0,Nick_name,str

## Requirements

If you have coloredlogs installed it will make use of it:
<https://pypi.org/project/coloredlogs/>
For the ```select``` and ```nmap``` commands, the ```jq``` utility is
required. It's available in most distros, or <https://stedolan.github.io/jq/>
For the ```nmap``` commands, the ```nmap``` utility is
required. It's available in most distros, or <https://nmap.org/>
## Future Directions
This has not been tested on Windwoes, but is should be simple to fix.
Because it's written in Python it is easy to extend to, for example,
rekeying a profile when copying a profile to a new device:
<https://git.plastiras.org/emdee/tox_profile/wiki/MultiDevice-Announcements-POC>
### Editing - save
The code now can generate a saved copy of the profile as it parses the profile.
Use the command ```--command save``` with ```--output``` and a filename,
to process the file with info to stderr, and it will save an copy of the file
to the ```--output``` (unencrypted).
It may be shorter than the original profile by up to 512 bytes, as the
original toxic profile is padded at the end with nulls. So this code
can be extended to edit the profile before saving it.
