Returns a basic +n+-bit checksum of the characters in +self+;
|
|
the checksum is the sum of the binary value of each byte in +self+,
|
|
modulo <tt>2**n - 1</tt>:
|
|
|
|
'hello'.sum # => 532
|
|
'hello'.sum(4) # => 4
|
|
'hello'.sum(64) # => 532
|
|
'тест'.sum # => 1405
|
|
'こんにちは'.sum # => 2582
|

This is not a particularly strong checksum.
