If either .Fa nid_key or .Fa nid_cert is set to -1, no encryption will be used. .Pp .Fa iter is the encryption algorithm iteration count to use and .Fa mac_iter is the MAC iteration count to use. If .Fa mac_iter is set to -1, the MAC will be omitted entirely. .Pp .Fa keytype is the type of key. .Pp The parameters .Fa nid_key , .Fa nid_cert , .Fa iter , .Fa mac_iter , and .Fa keytype can all be set to zero and sensible defaults will be used. .Pp 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. .Pp 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 .Fa mac_iter should be set to PKCS12_DEFAULT_ITER. .Pp .Fa 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 .Dv KEY_SIG the key can be used for signing only; and if set to .Dv 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. .Pp If a certificate contains an .Sy alias or .Sy keyid then this will be used for the corresponding .Sy friendlyName or .Sy localKeyID in the PKCS12 structure. .Sh SEE ALSO .Xr d2i_PKCS12 3 .Sh HISTORY PKCS12_create was added in OpenSSL 0.9.3. .Pp Before OpenSSL 0.9.8, neither .Fa pkey nor .Fa cert were allowed to be .Dv NULL , and a value of -1 was not allowed for .Fa nid_key , .Fa nid_cert , and .Fa mac_iter .
