|  | 28 | +## Description | 
|  | 29 | + | 
|  | 30 | +This is a small library to make use of some functions of the kernel keyring in Python. You can read, add and delete keys. | 
|  | 31 | + | 
|  | 32 | +It simply uses the keyctl command (invoking it via subprocess), so this util must be installed. | 
|  | 33 | + | 
|  | 34 | +Available functions: | 
|  | 35 | + | 
|  | 36 | + * **list** *(list all keys in keyring)* | 
|  | 37 | + * **describe** *(retrieve key name/description)* | 
|  | 38 | + * **read/pipe/print** *(retrieve key content)* | 
|  | 39 | + * **update** *(modify key content)* | 
|  | 40 | + * **add** *(add key)* | 
|  | 41 | + * **revoke/unlink** *(delete key)* | 
|  | 42 | + * **search/request** *(search for a key by name)* | 
|  | 43 | + * **clear** *(remove all keys from keyring)* | 
|  | 44 | + | 
|  | 45 | +There are many more functions with keys in the kernel keyring (e.g. permissions) that is needed for proper keymanagement. But for my usecase I just needed the given simple functionality.  | 
|  | 46 | + | 
|  | 47 | + | 
|  | 48 | +## Requirements | 
|  | 49 | + | 
|  | 50 | +Python 2.7 | 
|  | 51 | +``` | 
|  | 52 | +$ sudo apt-get install python2.7 | 
|  | 53 | +$ python --version | 
|  | 54 | +Python 2.7.3 | 
|  | 55 | +``` | 
|  | 56 | + | 
|  | 57 | +pip | 
|  | 58 | +``` | 
|  | 59 | +$ sudo apt-get install python-pip | 
|  | 60 | +$ pip --version | 
|  | 61 | +pip 9.0.1 from .... (python 2.7) | 
|  | 62 | +``` | 
|  | 63 | + | 
|  | 64 | +The 'keyctl' command | 
|  | 65 | +``` | 
|  | 66 | +$ sudo apt-get install keyutils | 
|  | 67 | +$ dpkg -s keyutils | grep Version | 
|  | 68 | +Version: 1.5.2-2 | 
|  | 69 | +``` | 
|  | 70 | + | 
|  | 71 | +For the GUI you also need: | 
|  | 72 | + | 
|  | 73 | +Qt4 | 
|  | 74 | +``` | 
|  | 75 | +google it for your distribution | 
|  | 76 | +``` | 
|  | 77 | + | 
|  | 78 | +PySide | 
|  | 79 | +``` | 
|  | 80 | +$ pip install pyside | 
|  | 81 | +$ pip show pyside | grep Version | 
|  | 82 | +Version: 1.2.4 | 
|  | 83 | +``` | 
|  | 84 | + | 
|  | 85 | + | 
|  | 86 | +## Installation | 
|  | 87 | + | 
|  | 88 | +``` | 
|  | 89 | +$ pip install keyctl | 
|  | 90 | +``` | 
|  | 91 | + | 
|  | 92 | +Ready to use. | 
|  | 93 | + | 
|  | 94 | + | 
|  | 95 | +## Usage | 
|  | 96 | + | 
|  | 97 | +### Module | 
|  | 98 | +Get all keys: | 
|  | 99 | +```python | 
|  | 100 | +from keyctl import Key | 
|  | 101 | +keylist = Key.list() | 
|  | 102 | +for mykey in keylist: | 
|  | 103 | +    print mykey.id | 
|  | 104 | +``` | 
|  | 105 | + | 
|  | 106 | +Read existing key: | 
|  | 107 | +```python | 
|  | 108 | +from keyctl import Key | 
|  | 109 | +mykey = Key(123) | 
|  | 110 | +print mykey.name | 
|  | 111 | +print mykey.data | 
|  | 112 | +print mykey.data_hex | 
|  | 113 | +``` | 
|  | 114 | + | 
|  | 115 | +Find key by name: | 
|  | 116 | +```python | 
|  | 117 | +from keyctl import Key | 
|  | 118 | +mykey = Key.search('test key') | 
|  | 119 | +print mykey.id | 
|  | 120 | +``` | 
|  | 121 | + | 
|  | 122 | +Add key: | 
|  | 123 | +```python | 
|  | 124 | +from keyctl import Key | 
|  | 125 | +mykey = Key.add('test key', 'test content') | 
|  | 126 | +print mykey.id | 
|  | 127 | +``` | 
|  | 128 | + | 
|  | 129 | +Delete key: | 
|  | 130 | +```python | 
|  | 131 | +from keyctl import Key | 
|  | 132 | +mykey = Key(123) | 
|  | 133 | +mykey.delete() | 
|  | 134 | +``` | 
|  | 135 | + | 
|  | 136 | +Update key: | 
|  | 137 | +```python | 
|  | 138 | +from keyctl import Key | 
|  | 139 | +mykey = Key(123) | 
|  | 140 | +mykey.update('new content') | 
|  | 141 | +``` | 
|  | 142 | + | 
|  | 143 | + | 
|  | 144 | +### GUI | 
|  | 145 | +To open the GUI, run the installed command. | 
|  | 146 | +``` | 
|  | 147 | +$ keyctlgui | 
|  | 148 | +``` | 
|  | 149 | + | 
|  | 150 | + | 
|  | 151 | +## Development | 
|  | 152 | + | 
|  | 153 | +### Warning | 
|  | 154 | + | 
|  | 155 | +If you run the integrated tests, your user keyring will be cleared. Don't do this when you have active keys e.g. for encryption. | 
|  | 156 | + |
