Changes between 0.9.3a and 0.9.4
+ *) Add to configuration table a new entry that can specify an alternative
+ name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
+ according to Mark Crispin <MRC@Panda.COM>.
+ [Bodo Moeller]
+
+#if 0
+ *) DES CBC did not update the IV. Weird.
+ [Ben Laurie]
+#else
+ Look at des.c, cbc3_enc.c etc.: Those rely on that bevaviour of
+ des_cbc_encrypt and copy IVs themselves when they have to.
+ Either all those have to be changed too, or things must stay as they
+ are.
+#endif
+
+ *) When bntest is run from "make test" it drives bc to check its
+ calculations, as well as internally checking them. If an internal check
+ fails, it needs to cause bc to give a non-zero result or make test carries
+ on without noticing the failure. Fixed.
+ [Ben Laurie]
+
+ *) DES library cleanups.
+ [Ulf Möller]
+
*) 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
*) Instead of "mkdir -p", which is not fully portable, use new
Perl script "util/mkdir-p.pl".
+ [Bodo Moeller]
*) Rewrite the way password based encryption (PBE) is handled. It used to
assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
