9 #include <openssl/pkcs12.h>
10
11 int PKCS12_parse(PKCS12 *p12, const char *pass, EVP_PKEY **pkey, X509 **cert,
12                  STACK_OF(X509) **ca);
13
14=head1 DESCRIPTION
15
16PKCS12_parse() parses a PKCS12 structure.
17
18B<p12> is the B<PKCS12> structure to parse. B<pass> is the passphrase to use.
19If successful the private key will be written to B<*pkey>, the corresponding
20certificate to B<*cert> and any additional certificates to B<*ca>.
21
22=head1 NOTES
23
24The parameters B<pkey> and B<cert> cannot be B<NULL>. B<ca> can be <NULL> in
25which case additional certificates will be discarded. B<*ca> can also be a
26valid STACK in which case additional certificates are appended to B<*ca>. If
27B<*ca> is B<NULL> a new STACK will be allocated.
28
29The B<friendlyName> and B<localKeyID> attributes (if present) on each
30certificate will be stored in the B<alias> and B<keyid> attributes of the
31B<X509> structure.
32
33The parameter B<pass> is interpreted as a string in the UTF-8 encoding. If it
34is not valid UTF-8, then it is assumed to be ISO8859-1 instead.
35
36In particular, this means that passwords in the locale character set
37(or code page on Windows) must potentially be converted to UTF-8 before
38use. This may include passwords from local text files, or input from
39the terminal or command line. Refer to the documentation of
40L<UI_OpenSSL(3)>, for example.
41
42=head1 RETURN VALUES
43
44PKCS12_parse() returns 1 for success and zero if an error occurred.
45
46The error can be obtained from L<ERR_get_error(3)>
47
48=head1 BUGS
49
50Only a single private key and corresponding certificate is returned by this
51function. More complex PKCS#12 files with multiple private keys will only
52return the first match.
53
54Only B<friendlyName> and B<localKeyID> attributes are currently stored in
55certificates. Other attributes are discarded.
56
57Attributes currently cannot be stored in the private key B<EVP_PKEY> structure.
