312-50V9 Question #425: Real Exam Question with Answer & Explanation
The correct answer is B: PGP. PGP uses asymmetric (public/private key) cryptography for key exchange, making it the only asymmetric encryption implementation among the choices.
Question
Which of the following is an example of an asymmetric encryption implementation?
Options
- ASHA1
- BPGP
- C3DES
- DMD5
Explanation
PGP uses asymmetric (public/private key) cryptography for key exchange, making it the only asymmetric encryption implementation among the choices.
Common mistakes.
- A. SHA1 is a one-way cryptographic hash function that produces a fixed-length digest and cannot encrypt or decrypt data.
- C. 3DES (Triple DES) is a symmetric encryption algorithm that uses the same shared key for both encryption and decryption.
- D. MD5 is a cryptographic hash function used for data integrity verification, not an encryption algorithm.
