PKCS12_create - create a PKCS#12 structure
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);
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 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
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
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.
PKCS12_create was added in OpenSSL 0.9.3
