| 3 | =head1 NAME | ||
| 4 | |||
| 5 | PKCS12_create - create a PKCS#12 structure | ||
| 6 | |||
| 7 | =head1 SYNOPSIS | ||
| 8 | |||
| 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 | |||
| 14 | =head1 DESCRIPTION | ||
| 15 | |||
| 16 | PKCS12_create() creates a PKCS#12 structure. | ||
| 17 | |||
| 18 | B<pass> is the passphrase to use. B<name> is the B<friendlyName> to use for | ||
| 19 | the supplied certifictate and key. B<pkey> is the private key to include in | ||
| 20 | the structure and B<cert> its corresponding certificates. B<ca>, if not B<NULL> | ||
| 21 | is an optional set of certificates to also include in the structure. | ||
| 22 | |||
| 23 | B<nid_key> and B<nid_cert> are the encryption algorithms that should be used | ||
| 24 | for the key and certificate respectively. B<iter> is the encryption algorithm | ||
| 25 | iteration count to use and B<mac_iter> is the MAC iteration count to use. | ||
| 26 | B<keytype> is the type of key. | ||
| 27 | |||
| 28 | =head1 NOTES | ||
| 29 | |||
| 30 | The parameters B<nid_key>, B<nid_cert>, B<iter>, B<mac_iter> and B<keytype> | ||
| 31 | can all be set to zero and sensible defaults will be used. | ||
| 32 | |||
| 33 | These defaults are: 40 bit RC2 encryption for certificates, triple DES | ||
| 34 | encryption for private keys, a key iteration count of PKCS12_DEFAULT_ITER | ||
| 35 | (currently 2048) and a MAC iteration count of 1. | ||
| 36 | |||
| 37 | The default MAC iteration count is 1 in order to retain compatibility with | ||
| 38 | old software which did not interpret MAC iteration counts. If such compatibility | ||
| 39 | is not required then B<mac_iter> should be set to PKCS12_DEFAULT_ITER. | ||
| 40 | |||
| 41 | B<keytype> adds a flag to the store private key. This is a non standard extension | ||
| 42 | that is only currently interpreted by MSIE. If set to zero the flag is omitted, | ||
| 43 | if set to B<KEY_SIG> the key can be used for signing only, if set to B<KEY_EX> | ||
| 44 | it can be used for signing and encryption. This option was useful for old | ||
| 45 | export grade software which could use signing only keys of arbitrary size but | ||
| 46 | had restrictions on the permissible sizes of keys which could be used for | ||
| 47 | encryption. | ||
| 48 | |||
| 49 | =head1 NEW FUNCTIONALITY IN OPENSSL 0.9.8 | ||
| 50 | |||
| 51 | Some additional functionality was added to PKCS12_create() in OpenSSL | ||
| 52 | 0.9.8. These extensions are detailed below. | ||
| 53 | |||
| 54 | If a certificate contains an B<alias> or B<keyid> then this will be | ||
| 55 | used for the corresponding B<friendlyName> or B<localKeyID> in the | ||
| 56 | PKCS12 structure. | ||
| 57 | |||
| 58 | Either B<pkey>, B<cert> or both can be B<NULL> to indicate that no key or | ||
| 59 | certficate is required. In previous versions both had to be present or | ||
| 60 | a fatal error is returned. | ||
| 61 | |||
| 62 | B<nid_key> or B<nid_cert> can be set to -1 indicating that no encryption | ||
| 63 | should be used. | ||
| 64 | |||
| 65 | B<mac_iter> can be set to -1 and the MAC will then be omitted entirely. | ||
