Verified usage

Verified import paths — ran on the pinned version, not inferred.

decode

✓ from endec import decode

✗ from endec import Base64

encode

✓ from endec import encode

✗ from endec import Base64

Basic usage: encode and decode bytes using the Base64 codec.

from endec import encode, decode, Base64 # Encode bytes to base64 string data = b"hello world" encoded = encode(data, Base64) print(encoded) # aGVsbG8gd29ybGQ= # Decode back decoded = decode(encoded, Base64) print(decoded) # b'hello world'

Debug

Known issues

breakingIn v0.4.0, dropped support for PyPy 3.9 and 3.10. If you use PyPy, ensure you are on PyPy 3.11+.

fix

Upgrade to PyPy 3.11+ or pin endec to <0.4.0.

affects: >=0.4.0

gotchaThe encode function expects bytes input. Passing a string will raise a TypeError.

fix

Ensure input is bytes: encode(b'text') not encode('text').

affects: *

gotchaThe decode function returns bytes, not a string. Many users expect a string for base64.

fix

Use .decode() on the result to get a string: decode(encoded, Base64).decode('utf-8').

affects: *
