Re: Calculate sha1 hash of a binary file

I did some testing, and calculating the hash value of a 1Gb file does take some time using this method. Would it be wise to calculate the hash value based on say for instance the first Mb? Is there a much larger chance of collusion this way (I suppose not). If it's helpful, the files would primaril

Calculate sha1 hash of a binary file

Hi - I'm trying to calculate unique hash values for binary files, independent of their location and filename, and I was wondering whether I'm going in the right direction. Basically, the hash values are calculated thusly: f = open('binaryfile.bin') import hashlib h = hashlib.sha1() h.update(f.re
