Detailed explanation-1: -Symmetric encryption is used to conceal the contents of blocks or streams of data of any size, including messages, files, encryption keys, and passwords.
Detailed explanation-2: -Symmetric encryption is a way to encrypt or hide the contents of material where the sender and receiver both use the same secret key.
Detailed explanation-3: -Symmetric encryption: used to conceal the contents of blocks or streams of data of any size, including messages, files, encryption keys, and passwords. Asymmetric encryption: used to conceal small blocks of data, such as encryption keys and hash function values, which are used in digital signatures.
Detailed explanation-4: -Symmetric-Key Algorithms for Encryption and Decryption Encryption provides confidentiality of data by transforming the “plaintext” into “ciphertext.” Decryption transforms ciphertext back to plaintext.
Detailed explanation-5: -AES is the symmetric algorithm of choice for most applications today, and it is widely used, typically with 128 or 256-bit keys, the latter of which is considered strong enough to protect military TOP SECRET data.
