symmetric and asymmetric encryption

what is Encryption

encryption is the process of converting readable data into unreadable data(ciphertext) to protect from unauthorised access

what is a key in encryption

a key is a rule or value used to control how data is encrypted and decrypted

what is symmetric encryption

a method where the same key is used for both encrypt and decrypt data

why is symmetric encryption insecure over networks

because the key must be shared, and if it is intercepted, the data can be decrypted

what is Asymmetric encryption

a method that uses a public key to encrypt and a private key to decrypt

why is asymmetric encryption more secure than symmetric encryption

because the private key is never shared, so only the intended receiver can decrypt the data

why are both types used together

asymmetric encryption is used to securely exchange a key, and symmetric encryptiom is used for fast data encryption+

Explain what is meant by symmetric encryption

Symmetric encryption is a method where the same key is used to encrypt and decrypt data. The sender uses the key to convert plaintext into ciphertext, and the receiver uses the same key to convert it back into plaintext.
