WebSecret key cryptography, also known as symmetric encryption, uses a single key to encrypt and decrypt a message. The sender encrypts the plaintext message using the key and sends it to the recipient who then uses the same key to decrypt it and unlock the original plaintext message. Stream Ciphers WebSymmetric encryption is the process of converting plaintext into ciphertext and vice versa using the same key. An encryption key is a random string of bits used to encrypt or decrypt data. It is, therefore, important that key is transferred between the sender and recipient using secure methods.
