I am working on a project which needs to add/update around 1 开发者_JAVA百科million urls daily. Some days are mostly updates and some days are mostly add and some days are mix.
if we take 32-bit CRC then the data word size will be 2 to th开发者_C百科e power of 32(2**32) plus 32 bit for CRC.... or not? Am I missing something?
I have to calculate cr开发者_开发知识库c32 on a lot of files, and also huge files (several GB). I tried several algo found on the web like Damieng or this one, and it works, but it is slow (more than
I\'ve been looking for the equivalent python method for the unix cksum comma开发者_如何学Gond: http://pubs.opengroup.org/onlinepubs/7990989775/xcu/cksum.html
I\'m using Python-2.6. I have very little knowledge of hash functions. I want to use a CRC hash function to hash an IP address like \'128.0.0.5\' into the range [0, H). Currently I\'m thinking of doi
I download a file and his checksum (generated by cksum Unix command). So, I want, in my C# app test if the Checksum is in adequation with the app I downloaded.
I\'ve been stuck on this for a few days now and can\'t seem to get it. I\'m hoping that by posting here, I\'ll have an epiphany and fix this issue 30 seconds after posting! :D
I use this trivial f开发者_开发百科unction to calculate the CRC checksum of a given file: long i, j = 0;
Is there an equivalent to md5sum/sha1sum in Linux for calculating SFV-style CRC32s?I checked out cksum, but it seems to be calculating a different sum (perhaps a different polynomial? or I\'m interpre
Is there any difference between the Java CRC32 implementations on 32Bit and 64Bit JVMs? My problem is, that my client application (on a 32Bit platform) calculates a hash and compares it against a hash
