go get toolman.org/encoding/base56Package base56 provides functions for encoding/decoding uint64 values as
short, easily digestible, base56 strings. For example, the Std encoding
transforms the uint64 value 1540840132 into the string "2nfvKM".
For compatibility with other implementions, this package supports three
separate and distinct base56 character sets through the package level,
Encoding variables Std, Alt and Py3. Each of these Encodings leverage
only 7-bit clean (ASCII) characters.
The Std Encoding employs the original character set used by this package and
is composed of the numerals 0-9 followed by all upper case characters except
for 'D' (0x44), 'I' (0x49), 'O' (0x4f), and 'Q' (0x51) and then all
lower case characters except for 'i' (0x69) and 'o' (0x6f).
The Alt Encoding is compatible with PHP and Java implementations and is
defined as the numerals 2-9 followed by all lower case characters except for
'l' (0x6c) and 'o' (0x6f) and then all upper case characters except for 'I'
(0x49) and 'O' (0x4f).
The Py3 Encoding is compatible with the Python-3 implementation and is
defined as the numerals 2-9 followed by all upper case characters except for
'I' (0x49) and 'O' (0x4f) and then all lower case characters except for 'l'
(0x6c) and 'o' (0x6f).
Note, the Alt and Py3 Encodings are identical except for the order of
character classes. Alt is numerals->lowercase->uppercase while Py3 is
numerals->uppercase->lowercase.
