Python Key Examples

Example #1

File: sequencer.py Project: named-data/ndn-lighting

	def getApplicationKey(self):
		print("getting application key for "+self.appCfg.appName)
		key = Key()
		keyFile = self.appCfg.keyFile
		key.fromPEM(filename=keyFile)
		self.appKey = key
		self.key = key

Example #2

File: repo_upload.py Project: named-data/PyCCN

    def publish(key, name, last_segment, content):
        print("Generating: %s" % name)

        # Name
        co_name = Name.Name(name)

        # SignedInfo
        si = ContentObject.SignedInfo()
        si.type = ContentObject.ContentType.CCN_CONTENT_DATA
        si.finalBlockID = last_segment
        si.publisherPublicKeyDigest = key.publicKeyID
        si.keyLocator = Key.KeyLocator(key)

        # ContentObject
        co = ContentObject.ContentObject()
        co.content = content
        co.name = co_name
        co.signedInfo = si

        co.sign(key)
        return co
