Question
Which of the following is considered the strongest type
of encryption method in modern cyber security practices?Solution
AES (Advanced Encryption Standard) is considered the most secure encryption standard used globally. It supports key lengths of 128, 192, or 256 bits, making it resistant to brute-force attacks. AES is widely used in various applications like VPNs, wireless security (WPA2), and government data protection due to its strength and efficiency. Caesar Cipher : An ancient, very weak encryption method based on shifting characters. DES : Once widely used but now considered insecure due to its short key length (56 bits). MD5 Hashing : This is a hashing algorithm, not an encryption method. It is vulnerable to collisions. RSA Encryption : While secure, RSA is mainly used for encrypting small pieces of data, such as encryption keys, rather than bulk data encryption like AES.
