Certified Network Defender (CND) — Question 183

Which of the following encryption techniques do digital signatures use?

Answer options

• A. MD5
• B. RSA
• C. Blowfish
• D. IDEA

Correct answer: A

Explanation

MD5 is a widely used hashing algorithm that, while not a strong encryption method, is commonly associated with digital signatures for integrity verification. RSA is an asymmetric encryption algorithm, but it is not used for signing directly. Blowfish and IDEA are symmetric encryption algorithms and do not pertain to the digital signature process.
