+<samp class="highlight">Q: Is CBC mode going to be replaced in SILC?</samp><br />
+A: Even if new encryption mode like CTR is introduced to SILC protocol the
+CBC mode will not likely go away. Recently new attacks has been
+introduced to the traditional CBC (IV is the previous ciphertext block),
+so looking additional modes for the future is wise. Another possiblity
+is to change the CBC to be so called randomized CBC (all IVs are random),
+however most likely this will not be done in SILC. Rather, new modes will
+be introduced instead.
