## Key Generation
|
||||
|
||||
### Phonetic
|
||||
|
||||
Attempts to generate phonetic keys, similar to `pwgen`
|
||||
|
||||
``` json
|
||||
{
|
||||
"type": "phonetic"
|
||||
}
|
||||
```
|
||||
|
||||
### Random
|
||||
|
||||
Generates a random key
|
||||
|
||||
``` json
|
||||
{
|
||||
"type": "random",
|
||||
"keyspace": "abcdef"
|
||||
}
|
||||
```
|
||||
|
||||
The _optional_ keySpace argument is a string of acceptable characters for the key.

||||
