Jun 15, 2009 · Only use CRC if computation resources are very tight (i.e. some embed environments) or you need to store/transport many output values and space/bandwidth is tight …

Feb 2, 2017 · SHA-256 takes 100 times as long as a CRC-32 or 50 times as long as a CityHash. And for no reason, since this is not an application that requires a cryptographic hash. – Mark …

May 13, 2013 · CRC was designed to prevent transmission errors, not malicious action. Therefore, it isn't collision resistant. In particular, the linear properties of CRC codes even …

Feb 16, 2022 · I found 19.00 generates the old CRCs correctly). (I'm running Windows 10.) The issue is with the CRC SHA context menu. For some reason it does not update correctly …

Mar 6, 2023 · Cyclic Redundancy Checks like CRC-32 are fast but collision-prone. They are not robust to collision attacks; somebody could take a given CRC and easily create a second input …

Aug 18, 2016 · The CRC SHA file context menu is missing an extremely simple feature: Once the hashes are displayed in a simple pop-up panel, it would be nice to be able to copy the hashes, …

Nov 30, 2024 · It's a cross platform utility designed for performing various checksumming activities. It supports verity of standards including ADLER-32, CRC-32, MD2, MD5, MURMUR …

Nov 19, 2009 · One approach might be to use a simple CRC-32 algorithm, and only if the CRC values compare equal, rerun the hash with a SHA1 or something more robust. A fast CRC-32 …

Mar 28, 2013 · The main difference between the three functions you've shown here is that sha1 and md5 are actually meant to be cryptographically secure. crc32 (crc stands for cyclic …

Apr 6, 2011 · A hash function is designed to avoid collisions. With MD5 or SHA-1, you will not get random collisions. If your setup is security-related (i.e. there is someone, somewhere, who …
