Which encryption algorithm is the least secured?

Show Suggested Answer Hide Answer
Suggested Answer: C

This answer is correct because DES (Data Encryption Standard) is the least secured encryption algorithm among the options given.DES uses a 56-bit key, which is too short and can be easily cracked by brute force attacks1.DES also suffers from other weaknesses, such as weak keys, complementation property, and linear cryptanalysis2.

The other answers are not correct because they are more secured encryption algorithms than DES.3DES (Triple DES) is an improvement over DES that applies DES three times with different keys, resulting in a 168-bit key3. AES-128 and AES-256 are variants of AES (Advanced Encryption Standard) that use 128-bit and 256-bit keys respectively. AES is considered to be the most secure symmetric encryption algorithm and is widely used for data protection.

Hmm, I'm feeling a bit 'DES-perate' about this one. Guess I'll just 'AES' my way through it.

That's true, AES-256 is the most secure option among these.

I'm going with C. DES is like a bulletproof vest made of tissue paper. Gotta love those '70s algorithms!

But AES-128 is stronger than DES, so it can't be the least secured.

AES-256 is the way to go, yo! Don't even try that outdated 3DES nonsense.

DES is the least secure, everyone knows that. The hackers just love to crack that old algorithm.

I agree, DES is definitely the least secure option.

I think 3DES is also not very secure compared to AES-128 and AES-256.

I disagree, I believe 3DES is less secure than DES.
