Question
MD5 is a ___________ algorithm
Options
- AOne way hash
- B3DES
- C192 bit
- DPKI
Explanation
MD5 is a cryptographic hash function that produces a fixed-size output, making it a one-way hash algorithm used for data integrity checks.
Common mistakes.
- B. 3DES (Triple Data Encryption Standard) is a symmetric-key block cipher, not a hash algorithm.
- C. While MD5 produces a 128-bit hash, "192 bit" refers to a specific key size often associated with symmetric encryption, not a type of algorithm itself.
- D. PKI (Public Key Infrastructure) is a system for creating, managing, distributing, and revoking digital certificates, not a specific hashing algorithm.
