Determines whether the given key is in the format of PEM key, and extracts the relevant part of the key if it is. Args: raw_key_input: The contents of a private key file (either PEM or PKCS12). Returns: string, The actual key if the contents are from a PEM file, or else None. s -----BEGIN N)find) raw_key_inputoffsets (lib/third_party/oauth2client/_helpers.py_parse_pem_keyr s+   /F |W%%c,[R"USS9$)N),:) separators)jsondumps)datas r _json_encoder)s ::dz 22r c[U[R5(aURU5OUn[U[R5(aU$[ SR U55e)aConverts a string value to bytes, if necessary. Unfortunately, ``six.b`` is insufficient for this task since in Python2 it does not modify ``unicode`` objects. Args: value: The string/bytes value to be converted. encoding: The encoding to use to convert unicode to bytes. Defaults to "ascii", which will not allow any characters from ordinals larger than 127. Other useful values are "latin-1", which which will only allows byte ordinals (up to 255) and "utf-8", which will encode any unicode that needs to be.
