url64
is the common name for the base64url
described in the
RFC4648 §5.
Since the original base64 alphabet contains invalid characters for URLs a safe
base64 for url is suggested, replacing the 62nd (plus sign +) and 63rd
(slash /) with new chars respectively the minus -
and underscore _
and
removing also the padding that is represented with the equal sign =
.
This a handy small utility to encode/decode strings in url64 with python3 very useful for JWT

import url64
encoded = url64.encode('Hello world!')
print(encoded) # SGVsbG8gd29ybGQh
dict_exncode = url64.encode(dict(alg="HS256", typ="JWT"))
print(dict_exncode) # eyJhbGciOiAiSFMyNTYiLCAidHlwIjogIkpXVCJ9
import url64
decoded = url64.decode('SGVsbG8gd29ybGQh')
print(decoded) # Hello world!
dict_decoded = url64.decode('eyJhbGciOiAiSFMyNTYiLCAidHlwIjogIkpXVCJ9')
print(dict_decoded) # {"alg": "HS256", "typ": "JWT"}
