-The current B<EVP> cipher interface is not as flexible as it should be. Only
-certain "spot" encryption algorithms can be used for ciphers which have various
-parameters associated with them (RC2, RC5 for example) this is inadequate.
+For RC5 the number of rounds can currently only be set to 8, 12 or 16. This is
+a limitation of the current RC5 code rather than the EVP interface.
+
+EVP_MAX_KEY_LENGTH and EVP_MAX_IV_LENGTH only refer to the internal ciphers with
+default key lengths. If custom ciphers exceed these values the results are
+unpredictable. This is because it has become standard practice to define a 
+generic key as a fixed unsigned char array containing EVP_MAX_KEY_LENGTH bytes.
+
+The ASN1 code is incomplete (and sometimes inaccurate) it has only been tested
+for certain common S/MIME ciphers (RC2, DES, triple DES) in CBC mode.

 RAND_seed() is equivalent to RAND_add() when B<num == entropy>.
 
+RAND_event() collects the entropy from Windows events such as mouse
+movements and other user interaction. It should be called with the
+B<iMsg>, B<wParam> and B<lParam> arguments of I<all> messages sent to
+the window procedure. It will estimate the entropy contained in the
+event message (if any), and add it to the PRNG. The program can then
+process the messages as usual.
+
 The RAND_screen() function is available for the convenience of Windows
 programmers. It adds the current contents of the screen to the PRNG.
-For applications that can catch Windows events, seeding the PRNG with
-the parameters of B<WM_MOUSEMOVE> events is a significantly better
-source of randomness. It should be noted that both methods cannot be
-used on servers that run without user interaction.
