While some cryptographically secure hash functions can make it hard to find these collisions, they still exist. In the same way, the strength of perceptual hash functions is also a major weakness.

Notice that I use the new function ORA_HASH to create a numeric hash value for the credit card. Now, you can simply query the data for a single credit card, and it automatically comes back in ...

I know, yeah yeah, big deal But I was wondering if I could get some help creating/printing a histogram of the hash table, w/ values on the y-axis and key on the x-axis. Thanks!

The 2025 paper claims that even without reordering elements over time, it is possible to construct a hash table using Krapivin's method that achieves far better probe complexity – the average ...

Rainbow table definition A rainbow table is a large, precomputed table designed to cache the output of cryptographic hash functions to decrypt hashed passwords into plaintext.
