CRC64ISO
Package for calculating checksums using 64-bit cyclic redundancy checks (CRC) according to the ISO 3309 standard.
Generator polynomial: x64 + x4 + x3 + x + 1
Reference: W. H. Press, S. A. Teukolsky, W. T. Vetterling, and B. P. Flannery, "Numerical recipes in C", 2nd ed., Cambridge University Press. Pages 896ff.
Requirements
- python 3.x
Examples
- Calculate 64-bit checksum from a string:
from crc64iso.crc64iso import crc64
checksum = crc64iso.crc64("ILOVEMATH")
- Calculate 64-bit checksum from incremental (bytes) data:
from crc64iso.crc64iso import crc64_pair, format_crc64_pair
crc_pair_1 = crc64_pair("ILOVE".encode())
crc_pair_2 = crc64_pair("MATH".encode(), crc_pair_1)
checksum = format_crc64_pair(crc_pair_2)
