Question
Which of the following is a hashing algorithm?
Options
- AMD5
- BPGP
- CDES
- DROT13
Explanation
MD5 is a one-way cryptographic hashing algorithm, whereas the other options are encryption ciphers or encoding schemes. Recognizing the distinction between hashing, encryption, and encoding is a core security concept.
Common mistakes.
- B. PGP (Pretty Good Privacy) is a data encryption and digital signing tool that combines symmetric and asymmetric encryption - it is not a hashing algorithm.
- C. DES (Data Encryption Standard) is a symmetric-key block cipher used for encryption and decryption of data, not a hashing algorithm.
- D. ROT13 is a simple reversible letter-substitution cipher that shifts characters by 13 positions - it is a reversible encoding scheme, not a one-way hash function.
