12 int nid_key, int nid_cert, int iter, int mac_iter, int keytype);

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
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
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.
