bases: A Python library for Base-N encodings
Bases provides a customisable, parametric implementation of several common styles of Base-N encoding, covering all cases appearing in the multibase specification (except for proquints).
Install
You can install the latest release from PyPI as follows:
$ pip install --upgrade basesUsage
We suggest you import bases as follows:
>>> import bases
Below are some basic usage examples, to get you started: for detailed documentation, see https://bases.readthedocs.io/
Base encoding objects
>>> from bases import base32
>>> base32
FixcharBaseEncoding(
StringAlphabet('ABCDEFGHIJKLMNOPQRSTUVWXYZ234567',
case_sensitive=False),
pad_char='=', padding='include')
Encoding
>>> b = bytes([70, 98, 190, 187, 66, 224, 178]) >>> base32.encode(b) 'IZRL5O2C4CZA===='
Decoding
>>> s = 'IZRL5O2C4CZA====' >>> base32.decode(s) b'Fb\xbe\xbbB\xe0\xb2' >>> list(base32.decode(s)) [70, 98, 190, 187, 66, 224, 178]
Case/padding variations
>>> b = bytes([70, 98, 190, 187, 66, 224, 178])
>>> base32.encode(b)
'IZRL5O2C4CZA===='
>>> base32lower = base32.lower()
>>> base32lower
FixcharBaseEncoding(
StringAlphabet('abcdefghijklmnopqrstuvwxyz234567',
case_sensitive=False),
pad_char='=', padding='include')
>>> base32lower.encode(b)
'izrl5o2c4cza===='
>>> base32nopad = base32.nopad()
>>> base32nopad.encode(b)
'IZRL5O2C4CZA'
Case sensitivity variations
>>> s = 'IZRL5O2C4CZA===='
>>> base32lower.decode(s)
b'Fb\xbe\xbbB\xe0\xb2'
>>> base32lower_casesensitive = base32lower.with_case_sensitivity(True)
>>> base32lower_casesensitive.decode(s)
bases.encoding.errors.NonAlphabeticCharError: Invalid character 'I'
encountered for alphabet StringAlphabet('abcdefghijklmnopqrstuvwxyz234567').
Custom base encodings
>>> base4 = bases.make("0123", kind="zeropad-enc", block_nchars=4)
>>> base4
ZeropadBaseEncoding(StringAlphabet('0123'), block_nchars=4)
