Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys for both the encryption of plaintext and the decryption of ciphertext. The keys may be identical, or there may be a simple transformation to go between the two keys.
How does symmetric key algorithm work?
Symmetric Encryption algorithm relies on a single key for encryption and decryption of information. Both the sender and receiver of the message need to have a pre-shared secret key that they will use to convert the plaintext into ciphertext and vice versa.
What is symmetric key example?
In cryptography, a symmetric key is one that is used both to encrypt and decrypt information. This means that to decrypt information, one must have the same key that was used to encrypt it.
