If such compatibility is not required then \fBmac_iter\fR should be set to \s-1PKCS12_DEFAULT_ITER.\s0 .PP \&\fBkeytype\fR adds a flag to the store private key. This is a non standard extension that is only currently interpreted by \s-1MSIE.\s0 If set to zero the flag is omitted, if set to \fB\s-1KEY_SIG\s0\fR the key can be used for signing only, if set to \fB\s-1KEY_EX\s0\fR 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. .SH "NEW FUNCTIONALITY IN OPENSSL 0.9.8" .IX Header "NEW FUNCTIONALITY IN OPENSSL 0.9.8" Some additional functionality was added to \fBPKCS12_create()\fR in OpenSSL 0.9.8. These extensions are detailed below. .PP If a certificate contains an \fBalias\fR or \fBkeyid\fR then this will be used for the corresponding \fBfriendlyName\fR or \fBlocalKeyID\fR in the \&\s-1PKCS12\s0 structure. .PP Either \fBpkey\fR, \fBcert\fR or both can be \fB\s-1NULL\s0\fR to indicate that no key or certficate is required. In previous versions both had to be present or a fatal error is returned. .PP \&\fBnid_key\fR or \fBnid_cert\fR can be set to \-1 indicating that no encryption should be used. .PP \&\fBmac_iter\fR can be set to \-1 and the \s-1MAC\s0 will then be omitted entirely. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBd2i_PKCS12\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" PKCS12_create was added in OpenSSL 0.9.3
