These are Python functions that are not directly related to the high-level APIs but are necessary to get them to work. They include a whole bunch of low-level CoreFoundation messing about and memory management. The concerns in this module are almost entirely about trying to avoid memory leaks and providing appropriate and useful assistance to the higher-level code. ) annotationsN) CFArrayCFConstCFData CFDictionaryCFMutableArrayCFString CFTypeRefCoreFoundationSecKeychainRefSecuritys;-----BEGIN CERTIFICATE----- (.*?) -----END CERTIFICATE-----c^tjtj|t|S)zv Given a bytestring, create a CFData object from it.
