This option is included for compatibility with previous versions, it used
to be needed to use MAC iterations counts but they are now used by default.

+a file or files containing random data used to seed the random number
+generator, or an EGD socket (see L<RAND_egd(3)|RAND_egd(3)>).
+Multiple files can be specified separated by a OS-dependent character.
+The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for
+all others.

for PKCS#12 file creation B<-export> and B<-name> are also used.
+If none of the B<-clcerts>, B<-cacerts> or B<-nocerts> options are present
+then all certificates will be output in the order they appear in the input
+PKCS#12 files. There is no guarantee that the first certificate present is
+the one corresponding to the private key. Certain software which requires
+a private key and certificate and assumes the first certificate in the
+file is the one corresponding to the private key: this may not always
+be the case. Using the B<-clcerts> option will solve this problem by only
+outputting the certificate corresponding to the private key. If the CA
+certificates are required then they can be output to a separate file using
+the B<-nokeys -cacerts> options to just output CA certificates.
+
The B<-keypbe> and B<-certpbe> algorithms allow the precise encryption
algorithms for private keys and certificates to be specified. Normally
the defaults are fine but occasionally software can't handle triple DES
Some would argue that the PKCS#12 standard is one big bug :-)
-Need password options for the PEM files: this will probably be fixed before
-release.
+Versions of OpenSSL before 0.9.6a had a bug in the PKCS#12 key generation
+routines. Under rare circumstances this could produce a PKCS#12 file encrypted
+with an invalid key. As a result some PKCS#12 files which triggered this bug
+from other implementations (MSIE or Netscape) could not be decrypted
+by OpenSSL and similarly OpenSSL could produce PKCS#12 files which could
+not be decrypted by other implementations. The chances of producing such
+a file are relatively small: less than 1 in 256.
+
+A side effect of fixing this bug is that any old invalidly encrypted PKCS#12
+files cannot no longer be parsed by the fixed version. Under such circumstances
+the B<pkcs12> utility will report that the MAC is OK but fail with a decryption
+error when extracting private keys.
+
+This problem can be resolved by extracting the private keys and certificates
+from the PKCS#12 file using an older version of OpenSSL and recreating the PKCS#12
+file from the keys and certificates using a newer version of OpenSSL. For example:
+
+ old-openssl -in bad.p12 -out keycerts.pem
+ openssl -in keycerts.pem -export -name "My PKCS#12 file" -out fixed.p12
