a4 Encode a piece of binary data into PEM format.
Args:
data (byte string):
The piece of binary data to encode.
marker (string):
The marker for the PEM block (e.g. "PUBLIC KEY").
Note that there is no official master list for all allowed markers.
Still, you can refer to the OpenSSL_ source code.
passphrase (byte string):
If given, the PEM block will be encrypted. The key is derived from
the passphrase.
randfunc (callable):
Random number generation function; it accepts an integer N and returns
a byte string of random data, N bytes long. If not given, a new one is
instantiated.
Returns:
The PEM block, as a string.

fS ) a Decode a PEM block into binary.
Args:
pem_data (string):
The PEM block.
passphrase (byte string):
If given and the PEM block is encrypted,
the key will be derived from the passphrase.
Returns:
A tuple with the binary data, the marker string, and a boolean to
indicate if decryption was performed.
Raises:
ValueError: if decoding fails, if the PEM file is encrypted and no passphrase has
been provided or if the passphrase is incorrect.
