5PKCS12_parse - parse a PKCS#12 structure

7=head1 SYNOPSIS
8
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
24Each of the parameters B<pkey>, B<cert>, and B<ca> can be NULL in which case
25the private key, the corresponding certificate, or the additional certificates,
26respectively, will be discarded.
27If any of B<pkey> and B<cert> is non-NULL the variable it points to is
28initialized.
29If B<ca> is non-NULL and B<*ca> is NULL a new STACK will be allocated.
30If B<ca> is non-NULL and B<*ca> is a valid STACK
31then additional certificates are appended in the given order to B<*ca>.
32
33The B<friendlyName> and B<localKeyID> attributes (if present) on each
34certificate will be stored in the B<alias> and B<keyid> attributes of the
35B<X509> structure.
36
37The parameter B<pass> is interpreted as a string in the UTF-8 encoding. If it
38is not valid UTF-8, then it is assumed to be ISO8859-1 instead.
39
40In particular, this means that passwords in the locale character set
41(or code page on Windows) must potentially be converted to UTF-8 before
42use. This may include passwords from local text files, or input from
43the terminal or command line. Refer to the documentation of
44L<UI_OpenSSL(3)>, for example.
45
46=head1 RETURN VALUES
47
48PKCS12_parse() returns 1 for success and zero if an error occurred.
49
50The error can be obtained from L<ERR_get_error(3)>
51
52=head1 BUGS
53
54Only a single private key and corresponding certificate is returned by this
55function. More complex PKCS#12 files with multiple private keys will only
56return the first match.
57
58Only B<friendlyName> and B<localKeyID> attributes are currently stored in
59certificates. Other attributes are discarded.
60
61Attributes currently cannot be stored in the private key B<EVP_PKEY> structure.
