WebbBlock cipher and stream cipher are members of the family of symmetric key ciphers, essentially encryption techniques used for directly transforming the plaintext into ciphertext. ... Salsa20. Salsa20 is a powerful, up-to-date encryption cipher that creates the encryption keystream using an expansion function. WebbIn 2005, Bernstein proposed the stream cipher Salsa20 [4] as a contender to the eSTREAM [19], the ECRYPT Stream Cipher Project. As outlined by the author, Salsa20 is an ARX type family of algorithms which can be ran with several number of rounds, including the well known Salsa20/12 and Salsa20/8 versions.
