tally-token is a Python library for split data into tokens with same length.
Tally is a historical object for prove something by splitting wood into tokens and matching tokens.
Medieval English split tally stick (front and reverse view). The stick is notched and inscribed to record a debt owed to the rural dean of Preston Candover, Hampshire, of a tithe of 20d each on 32 sheep, amounting to a total sum of £2 13s. 4d.

options:
-h, --help show this help message and exitYou can use split to split a file into multiple files.
$ tally-token split something.bin split-1.bin split-2.bin split-3.binYou can use merge to merge multiple files into a file.
$ tally-token merge merged.bin split-1.bin split-2.bin split-3.binNothing special. You can split and merge large file.
$ dd if=/dev/urandom of=original.1g.bin bs=1G count=1

'こんにちは'You can use split_bytes_into and merge_bytes_into to split and merge bytes.
This is useful for split binary data.
