Since public-key algorithms tend to be much slower than symmetric-key algorithms , modern systems such as TLS and SSH use a combination of the two : one party receives the other 's public key , and encrypts a small piece of data -LRB- either a symmetric key or some data used to generate it -RRB- .
Modern cryptographic systems include symmetric-key algorithms -LRB- such as DES and AES -RRB- and public-key algorithms -LRB- such as RSA -RRB- . Symmetric-key algorithms use a single shared key ; keeping data secret requires keeping this key secret .
