Changes between 0.9.3a and 0.9.4
+ *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
+ used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
+ ciphers. NOTE: although the key derivation function has been verified
+ against some published test vectors it has not been extensively tested
+ yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
+ of v2.0.
+ [Steve Henson]
+
*) Instead of "mkdir -p", which is not fully portable, use new
Perl script "util/mkdir-p.pl".
