COMPUTER FUNDAMENTALS

Detailed explanation-1: -Symmetric cryptography is faster to run (in terms of both encryption and decryption) because the keys used are much shorter than they are in asymmetric cryptography. Additionally, the fact that only one key gets used (versus two for asymmetric cryptography) also makes the entire process faster.

Detailed explanation-2: -Advantages of Symmetric Cryptography Symmetric cryptosystems are faster. Encrypted data can be transmitted over a network in Symmetric Cryptosystems even if it is certain that the data will be intercepted. Because no key is sent with the files, data decryption is impossible.

Detailed explanation-3: -As symmetric encryption employs a single key for encryption and decryption, it is quicker. Asymmetric encryption is slower than symmetric encryption because it employs two separate keys that are linked through a difficult mathematical procedure. Symmetric encryption is mostly used to transfer large amounts of data.

Detailed explanation-4: -Increased data security is the primary benefit of asymmetric cryptography. It is the most secure encryption process because users are never required to reveal or share their private keys, thus decreasing the chances of a cybercriminal discovering a user’s private key during transmission.

Detailed explanation-5: -Due to the better performance and faster speed of symmetric encryption (compared to asymmetric), symmetric cryptography is typically used for bulk encryption / encrypting large amounts of data, e.g. for database encryption.
