fletcher_32
fletcher_32(
data):number
Defined in: checksum/fletcher_32.ts:18
Computes the Fletcher-32 checksum of data (John Fletcher, 1982).
Two running sums mod 65535 of 16-bit little-endian words — the data bytes
are assembled into words two at a time, padding an odd-length input with an
implicit trailing zero byte. Stronger error detection than
fletcher_16 at comparable cost, and comparable to adler_32
with a slightly cheaper modulus (65535 rather than the prime 65521).
Complexity: O(n) in the byte length of data.
Parameters
Section titled “Parameters”Uint8Array
The bytes to check.
Returns
Section titled “Returns”number
An unsigned 32-bit checksum, the high 16 bits holding the sum of sums and the low 16 bits holding the sum of words.
