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 ...

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.

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 ...

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

Security researchers announced the first practical collision attack against the Secure Hash Algorithm-1 cryptographic function.
