Encryption is the process
of transforming plaintext into a less readable form (called ciphertext)
by using a mathematical process. The ciphertext is translated back
to plaintext for anyone who can supply the appropriate key, which
is necessary for decrypting (or unlocking) the ciphertext.
For details about setting up and using
encryption, see
Encryption in SAS. After an encryption service is set up in your environment, set a SAS encryption
option that is appropriate to the encryption service and requirements of the client
or the server session.
