PKI Key Python API - dogtagpki/pki GitHub Wiki
The key resource provides clients(agents only) to perform operations to fetch information related to keys.
The two operations available are to list all the keys and to retrieve a single key.
The KeyResource object requires a - PKIConnection object with the subsystem value set to "kra".
connection = PKIConnection(subsystem='kra') key_resource = KeyResource(connection)
See also:
list_keys(self, client_id=None, status=None, max_results=None, max_time=None, start=None, size=None)
List/Search archived secrets in the DRM. Performs a GET http request to https://<hostname>:<port>/kra/rest/agent/keys with the arguments passed as query parameters.
Parameters:
-
client_id — Client identifier (Any random unique secret identifier for client)
-
status — Status of the Key (ex: active)
-
max_results — Length of the list.
-
start, size — Parameters for pagination purposes.
Returns:
A KeyInfoCollection object which consists of an "entries" list of KeyInfo objects.
Exceptions:
-
PKIException — Raised if any error is thrown while retrieving data from the database.
Example Usage:
To list all the keys with specific clientUID and status:
key_resource.list_keys(client_uid='UUID: 123-45-6789 VEK Tue Feb 11 13:19:56 EST 2014',status='active')
which sends a http request like:
https://localhost:8443/kra/rest/agent/keys?status=active&client_id=UUID%3A+123-45-6789+VEK+Tue+Feb+11+13%3A19%3A56+EST+2014
for which the json response looks like:
{
"total": 1,
"entries": [
{
"keyURL": "https://localhost:8443/kra/rest/agent/keys/1",
"clientID": "UUID: 123-45-6789 VEK Tue Feb 11 13:19:56 EST 2014",
"status": "active",
"algorithm": "DES3",
"size": 0,
"ownerName": "IPA Agent"
}
],
"Link": []
}
where:
-
total: total number of records returned.
-
entries: list of KeyInfo objects with values of the KeyURL, clientUID, status, algorithm, size and the owner name.
-
Link: Any links related to the objects in the entries list.
Calling the method without any parameters i.e. key_resource.list_keys() lists all the keys stored.
retrieve_key(self, key_recovery_request)
Retrieve a secret from the DRM. A POST request is sent to the server to the URL /kra/rest/agent/keys/retrieve, with a KeyRecoveryRequest object as payload.
Parameters:
-
key_recovery_request — An object of the class KeyRecoveryRequest.
All the parameters required for searching and retrieving a specific key have to be added to the attribute list of a KeyRecoveryRequest. The parameters to be passed are:
-
keyId of the key to retrieve,
-
requestId of the key request used,
-
transWrappedSessionKey, a newly generated session key (used for wrapping the secret in the response) wrapped by the KRA transport cert (so the session key can only be read by the KRA),
-
nonceData.
Returns:
A KeyData object containing the wrapped secret.
Exceptions:
-
410 - Http Gone Exception — If there is no record satisfying the request.
-
PKIException — For internal failure.
Example Usage:
The json representation for a valid recovery request looks like:
{
"Attributes": {
"Attribute": [
{
"name": "keyId",
"value": "1"
},
{
"name": "requestId",
"value": "2"
},
{
"name": "transWrappedSessionKey",
"value": "69d4mU4P8W/hFmrP5q0Sh50zTMGToCzPcTRBZVfmR3rLEiQA1rs8ovZ93e4l/uUQ\r\n

},
{
"name": "nonceData",
"value": "8lVOywa9Scg=\r\n"
}
]
},
"ClassName":"com.netscape.certsrv.key.KeyRecoveryRequest"
}
The response consists of a KeyData object with information about the key such as the wrappedPrivateData (secret wrapped with the session key), nonce data, p12data, algorithm used, size.
For the above example request, the json representation of the response looks like:
{
"wrappedPrivateData":"LtjYfjWrrxCeQcPvr0aI8eRcmmF6h1tJf7X4gWj7gxY=\r\n",
"nonceData":"BGTbH7i77F4=\r\n",
"algorithm":"DES3",
"size":0
}
