serp-base64

Drop-in replacement for CPython's base64 module: bytes-in / bytes-out, written in the Serpentine subset.

API

• b64encode(s, altchars=None) / b64decode(s, altchars=None, validate=False)
• standard_b64encode/decode, urlsafe_b64encode/decode
• b32encode(s) / b32decode(s, casefold=False) — RFC 4648.
• b16encode(s) / b16decode(s, casefold=False) — uppercase hex.
• utf8_bytes(s) -> list[int] / utf8_text(list[int]) -> str — Serpentine extras kept for other libraries.

Divergences: decode errors raise ValueError (CPython raises binascii.Error, a ValueError subclass); inputs must be bytes (CPython also accepts ASCII str); a85/b85/b32hex variants are not provided.
