Note: the last bullet means I am fully aware of, and prepared for, collisions. WebCRC checksums cannot be used to verify the authenticity of files, as CRC32 is not a collision resistant hash function -- even if the hash sum file is not tampered with, it is computationally trivial for an attacker to replace a file with the same CRC digest as the original file, meaning that a malicious change in the file is not detected by a CRC …

WebFeb 1, 2024 · CRC64 vs. 8-byte hash Data blocks are to be transferred over network and stored on disk, repeatedly. Blocks can be 1KB to 1GB in size.
