-If none of the

-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
-.Fl clcerts
-option will solve this problem by only outputting the certificate
-corresponding to the private key.
-If the CA certificates are required, they can be output to a separate
-file using the
-.Fl nokeys
-and
-.Fl cacerts
-options to just output CA certificates.

-Normally, the defaults are fine but occasionally software can't handle
-triple DES encrypted private keys;
-then the option

-.Sh PKCS12 BUGS
-Some would argue that the PKCS#12 standard is one big bug :\-)
-.Pp
-Versions of
-.Nm 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
-.Pq MSIE or Netscape
-could not be decrypted by
-.Nm OpenSSL
-and similarly
-.Nm 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.
-.Pp
-A side effect of fixing this bug is that any old invalidly encrypted PKCS#12
-files can no longer be parsed by the fixed version.
-Under such circumstances the
-.Nm pkcs12
-utility will report that the MAC is OK but fail with a decryption
-error when extracting private keys.
-.Pp
-This problem can be resolved by extracting the private keys and certificates
-from the PKCS#12 file using an older version of
-.Nm OpenSSL
-and recreating
-the PKCS#12 file from the keys and certificates using a newer version of
-.Nm OpenSSL .
-For example:
-.Bd -literal -offset indent
-$ old-openssl -in bad.p12 -out keycerts.pem
-$ openssl -in keycerts.pem -export -name "My PKCS#12 file" \e
-	-out fixed.p12
