[1]
Which of the following concepts are described above? (Choose two.)

Answer options

• A. Salting
• B. Collision
• C. Steganography
• D. Hashing
• E. Key stretching

Correct answer: B, D

Explanation

The MD5 hash shown indicates the use of hashing, which is a process of converting data into a fixed-size string of characters, which is represented here. Collision refers to a scenario where two different inputs produce the same hash output, which is relevant to MD5's known vulnerabilities, while options A, C, and E do not directly relate to the information provided.
