Answer: A

Explanation:

Hashing is a cryptographic technique where an input (data/message) is processed through an algorithm to produce a fixed-size output, known as a hash value. The key characteristic of hashing is that it is a one-way function, meaning that it is computationally infeasible to reverse the process and derive the original input from the hash value. Hashing is commonly used to verify data integrity, as even a small change in the input will result in a significantly different hash value.
