base64

Convert binary data to and from the standard Base64 alphabet.

Function	Input and output
b64encode(data)	bytes to encoded bytes.
b64decode(data)	Encoded str or bytes to decoded bytes.

import base64

encoded = base64.b64encode(b'hello')
assert encoded == b'aGVsbG8='
assert base64.b64decode(encoded) == b'hello'
assert base64.b64decode('aGVsbG8=') == b'hello'

Only these two functions are provided. There are no URL-safe alphabet, alternate-alphabet, or validate= options. Malformed input can return empty bytes instead of raising an error, so do not use the decoder as an input validator.

Implementation: base64.c.
