Question

Which of the following best describes cryptographic hashing?
A uniform length, one-way value calculated from an input
A method of sending data securely
Full Disk Encryption
A method of sending decryptable messages only decryptable with the sender's private key

Answer 1

The option that best describes cryptographic hashing is:

**A uniform length, one-way value calculated from an input.**

Cryptographic hashing takes an input (or "message") and produces a fixed-size string of characters, which is typically a sequence of numbers and/or letters, regardless of the input's size. This process is one-way, meaning it is computationally infeasible to reverse the hash back to the original input.
