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 ...

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 ...

Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature.

For more than six years, the SHA1 cryptographic hash function underpinning Internet security has been at death's door.
