NAME
PKCS12_create - create a PKCS#12 structure
SYNOPSIS
#include <openssl/pkcs12.h>
PKCS12 *PKCS12_create(char *pass, char *name, EVP_PKEY *pkey, X509 *cert, STACK_OF(X509) *ca,
int nid_key, int nid_cert, int iter, int mac_iter, int keytype);
DESCRIPTION
PKCS12_create() creates a PKCS#12 structure.
pass is the passphrase to use. name is the friendlyName to use for the
supplied certifictate and key. pkey is the private key to include in
the structure and cert its corresponding certificates. ca, if not NULL
is an optional set of certificates to also include in the structure.
nid_key and nid_cert are the encryption algorithms that should be used
for the key and certificate respectively. iter is the encryption
algorithm iteration count to use and mac_iter is the MAC iteration
count to use. keytype is the type of key.

NOTES
The parameters nid_key, nid_cert, iter, mac_iter and keytype can all be
set to zero and sensible defaults will be used.
These defaults are: triple DES encryption for certificates and private
keys, a key iteration count of PKCS12_DEFAULT_ITER (currently 2048) and
a MAC iteration count of 1.
The default MAC iteration count is 1 in order to retain compatibility
with old software which did not interpret MAC iteration counts. If such
compatibility is not required then mac_iter should be set to
PKCS12_DEFAULT_ITER.
keytype adds a flag to the store private key. This is a non standard
extension that is only currently interpreted by MSIE. If set to zero
the flag is omitted, if set to KEY_SIG the key can be used for signing
only, if set to KEY_EX it can be used for signing and encryption. This
option was useful for old export grade software which could use signing
only keys of arbitrary size but had restrictions on the permissible
sizes of keys which could be used for encryption.

NEW FUNCTIONALITY IN OPENSSL 0.9.8
Some additional functionality was added to PKCS12_create() in OpenSSL
0.9.8. These extensions are detailed below.
If a certificate contains an alias or keyid then this will be used for
the corresponding friendlyName or localKeyID in the PKCS12 structure.
Either pkey, cert or both can be NULL to indicate that no key or
certficate is required. In previous versions both had to be present or
a fatal error is returned.
nid_key or nid_cert can be set to -1 indicating that no encryption
should be used.
mac_iter can be set to -1 and the MAC will then be omitted entirely.
