     <p>The use of the <code>-b</code> option is discouraged, since when it is
     used the unencrypted password appears on the command line.</p>

+    <p>When using the <code>crypt()</code> algorithm, note that only the first
+    8 characters of the password are used  to form the password. If the supplied
+    password is longer, the extra characters will be silently discarded.</p>

+    <p>The SHA encryption format does not use salting: for a given password,
+    there is only one encrypted representation. The <code>crypt()</code> and
+    MD5 formats permute the representation by prepending a random salt string,
+    to make dictionary attacks against the passwords more difficult.</p>
