WebbThere are three primary types of modern encryption: symmetric, asymmetric, and hashing. Symmetric cryptography uses a single key to encrypt and decrypt. Asymmetric cryptography uses two keys, one to encrypt and the other to decrypt. Hashing is a one-way cryptographic transformation using an algorithm, but no key.

"Symmetric ciphers have historically been susceptible to known-plaintext attacks, chosen-plaintext attacks, differential cryptanalysis and linear cryptanalysis. Careful construction of the functions for each round can greatly reduce the chances of a successful attack. It is also possible to increase the key length or the rounds in the encryption process to better protect against attack. This, however, tends to increase the processing power and decrease the speed at which the process … " - History of symmetric encryption

WebbThe first recorded use of cryptography for correspondence was by the Spartans, who as early as 400 bc employed a cipher device called the scytale for secret communication between military commanders. The scytale consisted of a tapered baton, around which was spirally wrapped a strip of parchment or leather on which the message was then written. http://geekdaxue.co/read/tendermint-docs-zh/architecture-adr-013-symmetric-crypto.md
