Git commit hash collision

WebA Hash Collision Attack is an attempt to find two input strings of a hash function that produce the same hash result. Because hash functions have infinite input length and a predefined output length, there is inevitably going to be the possibility of two different inputs that produce the same output hash. If two separate inputs produce the same hash … WebBut an interpolation of the entries for 32 and 48 characters lands us in the range of 5*10 22 git commits for a 0.1% probability of a collision.

WebMost DVCS tools, including Git, Mercurial, and Veracity, use cryptographic hashes. A cryptographic hash is an algorithm which constructs a short digest from a sequence of bytes of any length.

Some hash algorithms, including SHA-2 [] and Skein … WebNeuralHash is a perceptual hash function that uses a neural network. Images are resized to 360x360 and passed through a neural network to produce a 128-dimensional feature vector. Then, the vector is projected onto R^96 using a 128x96 "seed" matrix.

Do you ever have discussions with your colleagues about how many Git hash digits should be used to reference Git commits within your Git repository? The probability of a commit hash collision, of course, depends on the number of digits you track and the number of commits you expect.
