Symmetric Encryption. Symmetric encryption (or pre-shared key encryption) uses a single key to both encrypt and decrypt data. Both the sender and the receiver need the same key to communicate. Symmetric key sizes are typically 128 or 256 bitsâthe larger the key size, the harder the key is to crack.
Symmetric vs Asymmetric Encryption. Encryption is a key concept in cryptography. It is the process in which one can encode a message to a format that canât be read by an eavesdropper.It is an age old technique, and one popular ancient use case was found in Caesarâs messages, which were encrypted using Caesar cipher.symmetric Encryption. Asymmetric encryption is also known as public key cryptography which is a relatively new area compared to symmetric encryption. Asymmetric encryption uses two keys to encrypt your plain text. This came to the arena to address an inherent problem with the symmetric cipher.
