Question
Which cryptographic process involves applying a
mathematical function to generate a fixed-size output from variable-size input?Solution
Hashing is the process of applying a hash function to generate a fixed-size output (hash value) from variable-size input (data). Hashing is used for data integrity checks, password storage, and various other security applications.
