Syskey is discussed in this class to illustrate a critical point about cryptographic controls: There are sometimes bugs in implementations that are exploited in spite of the encryption itself being strong. There are times when the data must be held in a decrypted state outside of the protection of the encryption system. Also, in order to protect against offline brute forcing, some algorithms introduce a variable at the time of decryption that, it is could be predicted, would leave the data still vulnerable to attack.
