What technique creates different hashes for the same password?Select one:SHA-256HMACCRCsalting

Break Down the Problem

1. Identify the key question: What technique is used to create different hashes for the same password?
2. Review the options provided: SHA-256, HMAC, CRC, salting.

Relevant Concepts

3. SHA-256: A hashing algorithm that produces the same hash for the same input.
4. HMAC: A mechanism that combines a hashing function with a secret key but does not change the hash for the same input unless the key changes.
5. CRC: A checksum algorithm primarily used for error-checking, not for hashing passwords.
6. Salting: A technique that involves adding a random value (salt) to the password before hashing, producing a unique hash for the same password.

Analysis and Detail

7. The correct answer focuses on techniques that introduce variability into the hashing process. While SHA-256, HMAC, and CRC do not inherently create different hashes for the same input, salting changes the input by combining it with a random salt each time, leading to different hashes from the same password.

Verify and Summarize

8. After analyzing the options, salting is the only method listed that guarantees different hashes for identical passwords each time the hashing is applied.

Final Answer

The correct technique that creates different hashes for the same password is salting.
