A cryptographic primitive is a fundamental building block of cryptographic systems, such as encryption algorithms or hash functions. These primitives are designed to perform specific security-related tasks and are typically characterized by their mathematical properties and resistance to known attacks. They form the basis for constructing more complex cryptographic protocols and applications.
