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.
