.Sh SYNOPSIS

.Fa "const char *name"
.Fa "EVP_PKEY *pkey"

.Fc
.Sh DESCRIPTION
.Fn PKCS12_create
creates a PKCS#12 structure.
.Pp
.Fa pass
is the passphrase to use.
.Fa name
is the
.Sy friendlyName
to use for the supplied certificate and key.
.Fa pkey
is the private key to include in the structure and
.Fa cert
its corresponding certificates.
.Fa ca
is an optional set of certificates to also include in the structure.
.Fa pkey ,
.Fa cert ,
or both can be
.Dv NULL
to indicate that no key or certificate is required.
.Pp
.Fa nid_key
and
.Fa nid_cert
are the encryption algorithms that should be used for the key and
certificate, respectively.
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 RETURN VALUES
.Fn PKCS12_create
returns a valid
.Vt PKCS12
structure or
.Dv NULL
if an error occurred.
.Sh SEE ALSO
.Xr crypto 3 ,
.Xr d2i_PKCS12 3 ,
.Xr PKCS12_new 3 ,
.Xr PKCS12_newpass 3 ,
.Xr PKCS12_parse 3 ,
.Xr PKCS12_SAFEBAG_new 3
.Sh HISTORY
.Fn PKCS12_create
first appeared in OpenSSL 0.9.3 and has been available since
.Ox 2.6 .
.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 .
