a single key is used

algorithms are DES, IDEA and !
TwoFish, etc. These systems have encrypt data with key in such
a way that recovering the data without the key is very, very hard

These algorthims are
used in many
PublicKeyEncryption systems too

These algorithms generally also
used in most
PublicKeyEncryption systems as workhorses once a trusted channel has been established by other means
, since they
're much less comutationally intensive and better suited for bulk data transfers
