PKCS12_parse \- parse a PKCS#12 structure
.SH "SYNOPSIS"

.Vb 1
\& #include <openssl/pkcs12.h>
\&
\& int PKCS12_parse(PKCS12 *p12, const char *pass, EVP_PKEY **pkey, X509 **cert,
\&                  STACK_OF(X509) **ca);
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBPKCS12_parse()\fR parses a \s-1PKCS12\s0 structure.
.PP
\&\fBp12\fR is the \fB\s-1PKCS12\s0\fR structure to parse. \fBpass\fR is the passphrase to use.
If successful the private key will be written to \fB*pkey\fR, the corresponding
certificate to \fB*cert\fR and any additional certificates to \fB*ca\fR.
.SH "NOTES"
.IX Header "NOTES"
The parameters \fBpkey\fR and \fBcert\fR cannot be \fB\s-1NULL\s0\fR. \fBca\fR can be <\s-1NULL\s0> in
which case additional certificates will be discarded. \fB*ca\fR can also be a
valid \s-1STACK\s0 in which case additional certificates are appended to \fB*ca\fR. If
\&\fB*ca\fR is \fB\s-1NULL\s0\fR a new \s-1STACK\s0 will be allocated.
.PP
The \fBfriendlyName\fR and \fBlocalKeyID\fR attributes (if present) on each
certificate will be stored in the \fBalias\fR and \fBkeyid\fR attributes of the
\&\fBX509\fR structure.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBPKCS12_parse()\fR returns 1 for success and zero if an error occurred.
.PP
The error can be obtained from \fBERR_get_error\fR\|(3)
.SH "BUGS"
.IX Header "BUGS"
Only a single private key and corresponding certificate is returned by this
function. More complex PKCS#12 files with multiple private keys will only
return the first match.
.PP
Only \fBfriendlyName\fR and \fBlocalKeyID\fR attributes are currently stored in
certificates. Other attributes are discarded.
.PP
Attributes currently cannot be stored in the private key \fB\s-1EVP_PKEY\s0\fR structure.
