Remove the new line “\n” from base64 encoded strings in Python3?

Question

I\'m trying to make a HTTPS connection in Python3 and when I try to encode my username and password the base64 encodebytes method returns the encoded v

Answer 1

Instead of encodestring consider using b64encode. Later does not add \n characters. e.g.

In [11]: auth = b'username@domain.com:passWORD'

In [12]: base64.encodestring(auth)
Out[12]: b'dXNlcm5hbWVAZG9tYWluLmNvbTpwYXNzV09SRA==\n'

In [13]: base64.b64encode(auth)
Out[13]: b'dXNlcm5hbWVAZG9tYWluLmNvbTpwYXNzV09SRA=='

It produces identical encoded string except the \n

Answer 2

Following code would work

auth_base64 = auth_base64.decode('utf-8').replace('\n', '')

Answer 3

for python3 use:-

binascii.b2a_base64(cipher_text, newline=False)

for python2 use:

binascii.b2a_base64(cipher_text)[:-1]

Answer 4

I concur with Mandar's observation that base64.xxxx_encode() would produce output without line wrap \n.

For those who want a more confident understanding than merely an observation, these are the official promise (sort of), that I can find on this topic. The Python 3 documentation does mention base64.encode(...) would add newlines after every 76 bytes of output. Comparing to that, all other *_encode(...) functions do not mention their linewrap behavior at all, which can argurably be considered as "no line wrap behavior". For what it's worth, the Python 2 documentation does not mention anything about line wrap at all.
