PKCS12_create — create a PKCS#12 structure
*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,
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.
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: 40 bit RC2 encryption for certificates,
triple DES encryption for private keys, a key iteration count of
PKCS12_DEFAULT_ITER (currently 2048) and a MAC iteration count of
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.
PKCS12_create was added in OpenSSL 0.9.3
