Standard library

nox.base64

Base64 encoding and decoding of text, in the standard and the URL-safe alphabets.

Text

import nox.base64
from nox.base64 import Base64Error

Capability: none registered; the module is pure Nox and works wherever the compiler's hosted profile does (it is not on the freestanding allow-list).

Functions#

Function	Description
`encode(data)`	standard Base64 (`+`, `/`) with `=` padding
`encode_url(data)`	URL-safe Base64 (`-`, `_`) without padding, as used in JWTs
`decode(s)`	decodes either alphabet, with or without padding; raises `Base64Error` for invalid input

Input and output are str. The data is processed as the UTF-8 bytes of the string.

Nox

import nox.base64

print(nox.base64.encode("hello"), nox.base64.decode("aGVsbG8="))
print(nox.base64.encode_url("??>>"), nox.base64.decode("Pz8-Pg"))

Output

aGVsbG8= hello
Pz8-Pg ??>>

For binary data, convert bytes to a string with nox.strings.char_from_byte first, or use nox.gzip's list[int] byte API for compression.
