Which of the following is a symmetric encryption algorithm?

3DES (Triple Data Encryption Standard) is a symmetric encryption algorithm. It uses the same key for both encryption and decryption, distinguishing it from asymmetric algorithms.

Symmetric Encryption Overview:

Symmetric encryption uses a single key shared between the sender and receiver for encrypting and decrypting data.

3DES Mechanism:

3DES encrypts data three times using the DES algorithm with three different keys, enhancing security over the original DES.

Comparison with Other Options:

MD5: Not an encryption algorithm; it’s a cryptographic hash function.

ECC (Elliptic Curve Cryptography) and RSA: Both are asymmetric algorithms, using separate public and private keys.

Applications:

Widely used in financial services, although increasingly replaced by more secure algorithms like AES.

Encryption Fundamentals: EC-Council identifies 3DES as a legacy symmetric encryption method, suitable for understanding encryption evolution.

Security Practices: Guidance on transitioning from 3DES to modern algorithms aligns with EC-Council’s focus on advanced security.
