NAME

6       PKCS12_create - create a PKCS#12 structure
7

SYNOPSIS

9        #include <openssl/pkcs12.h>
10
11        PKCS12 *PKCS12_create(char *pass, char *name, EVP_PKEY *pkey, X509 *cert, STACK_OF(X509) *ca,
12                                       int nid_key, int nid_cert, int iter, int mac_iter, int keytype);
13

DESCRIPTION

15       PKCS12_create() creates a PKCS#12 structure.
16
17       pass is the passphrase to use. name is the friendlyName to use for the
18       supplied certifictate and key. pkey is the private key to include in
19       the structure and cert its corresponding certificates. ca, if not NULL
20       is an optional set of certificates to also include in the structure.
21
22       nid_key and nid_cert are the encryption algorithms that should be used
23       for the key and certificate respectively. iter is the encryption algo‐
24       rithm iteration count to use and mac_iter is the MAC iteration count to
25       use.  keytype is the type of key.
26

NOTES

28       The parameters nid_key, nid_cert, iter, mac_iter and keytype can all be
29       set to zero and sensible defaults will be used.
30
31       These defaults are: 40 bit RC2 encryption for certificates, triple DES
32       encryption for private keys, a key iteration count of
33       PKCS12_DEFAULT_ITER (currently 2048) and a MAC iteration count of 1.
34
35       The default MAC iteration count is 1 in order to retain compatibility
36       with old software which did not interpret MAC iteration counts. If such
37       compatibility is not required then mac_iter should be set to
38       PKCS12_DEFAULT_ITER.
39
40       keytype adds a flag to the store private key. This is a non standard
41       extension that is only currently interpreted by MSIE. If set to zero
42       the flag is omitted, if set to KEY_SIG the key can be used for signing
43       only, if set to KEY_EX it can be used for signing and encryption. This
44       option was useful for old export grade software which could use signing
45       only keys of arbitrary size but had restrictions on the permissible
46       sizes of keys which could be used for encryption.
47

NEW FUNCTIONALITY IN OPENSSL 0.9.8

49       Some additional functionality was added to PKCS12_create() in OpenSSL
50       0.9.8. These extensions are detailed below.
51
52       If a certificate contains an alias or keyid then this will be used for
53       the corresponding friendlyName or localKeyID in the PKCS12 structure.
54
55       Either pkey, cert or both can be NULL to indicate that no key or
56       certficate is required. In previous versions both had to be present or
57       a fatal error is returned.
58
59       nid_key or nid_cert can be set to -1 indicating that no encryption
60       should be used.
61
62       mac_iter can be set to -1 and the MAC will then be omitted entirely.
