It mainly involves using a single key, called a secret key, used for encrypting and decrypting the data. It’s also referred to as private-key cryptography, as well as secret-key, shared-key, one-key, and private-key encryption.

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. The keys, in practice, represent a shared … See more Symmetric-key encryption can use either stream ciphers or block ciphers. • Stream ciphers encrypt the digits (typically bytes), or letters (in substitution ciphers) of a message one at a time. An example is See more Examples of popular symmetric-key algorithms include Twofish, Serpent, AES (Rijndael), Camellia, Salsa20, ChaCha20, Blowfish See more Many modern block ciphers are based on a construction proposed by Horst Feistel.
