New submission from Maciej Piechorka: In documentation it is specified that cadata parameter in load_verify_locations is 'an ASCII string of one or more PEM-encoded certificates'. However the code is actually determining it based on PyUnicode_Check function so the 'ASCII string' actually needs to be unicode object. In Python 3 it seems to be fixed by checking by PyObject_GetBuffer. ---------- assignee: docs@python components: Documentation, SSL messages: 285176 nosy: docs@python, uzytkownik priority: normal severity: normal status: open title: 'an ASCII string of one or more PEM-encoded certificates' needs to be unicode versions: Python 2.7 _______________________________________ Python tracker http://bugs.python.org/issue29236 _______________________________________
