Before the advent of asymmetric encryption in the 1970s, symmetric … 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. Feistel's construction makes it possible to build invertible … See more Symmetric-key algorithms require both the sender and the recipient of a message to have the same secret key. All early cryptographic … See more Symmetric ciphers are commonly used to achieve other cryptographic primitives than just encryption. Encrypting a message does not guarantee that it will remain … See more Symmetric ciphers have historically been susceptible to known-plaintext attacks, chosen-plaintext attacks, differential cryptanalysis See more When used with asymmetric ciphers for key transfer, pseudorandom key generators are nearly always used to generate the symmetric cipher session keys.
