PKCS12_create(3)             OpenSSL             PKCS12_create(3)

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: 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
     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.
