👉 In cryptography, a "card-sharper" is a type of cryptographic algorithm that uses a finite field to perform operations on large integers. This makes it particularly useful for performing computations with large numbers due to the difficulty in factorizing large integers into smaller prime factors. Card-sharings are typically used in elliptic curve cryptography (ECC) and other cryptographic protocols, where the key is generated from a finite set of points on an elliptic curve over a finite field.
