Base 64 encoding/decoding

b2a_base64 converts a bytes object to a Base64 representation.

a2b_base64 does the opposite.

>>> import binascii
>>> print(binascii.b2a_base64(b'hello world', newline=False).decode('ascii'))
aGVsbG8gd29ybGQ=
>>> print(binascii.a2b_base64(b'aGVsbG8gd29ybGQ=').decode('ascii'))
hello world

Convert bytes to hexadecimal representation and vice versa

>>> binascii.hexlify(b'Rene\x17')
b'52656e6517'
>>> binascii.unhexlify(b'52656e6517')
b'Rene\x17'

Note that hexlify() returns a bytes object.

A string object can be obtained by directly calling .hex() on the bytes object:

>>> b'ABC'.hex()
'414243'
